    Application Instructions

    Surface Preparation

    To insure proper primer adhesion to the substrate, all substrate to be prepared, different methods should be used. There are a variety of processes to prepare these substrates for primer and painting.

    Sherwin-Williams primers are designed to go over various treatments (i.e., alclad or anodized aluminum, composite, fiberglass, magnesium, and stainless steel). Please refer to recommendations for cleaning, application, and preparation before painting to the manufacturer of the treatment.

    If a wash primer is needed, please refer to the Product Data Sheet for CM0484684 Wash Primer.

    Mixing Instructions

    Shake primer component for 15 minutes before admixing.

    Admix by Volume:
    4 Parts Epoxy Primer CM0481968
    1 Part Epoxy Adduct CM0120828

    Add the Adduct into the Primer Component, stir thoroughly.

    Thinning Instructions

    Corrosion Primer Application (Non-Sand System)
    The product can be reduced using up to 1 part of the following Reducers:

    • CM0110944 - Fast
    • CM0110099 - Medium
    • CM0110933 - Slow

    Surfacer Application (High Build System)
    The product can also be reduced by 10% with:

    • CM0110944 US Exempt Reducer – For small parts or cool conditions
    • CM0110099 Medium Reducer
    • CM0110933 – For full repaints or hot conditions

    Ready to Spray product should be allowed a 30-minute induction time for optimum application performance.

    It is recommended to filter strain admixed and reduced primer before placing material in containers for spraying.

    Guidecoat Colorant to Assist in Sanding (Optional)

    To create color contrast when sanding, add up to 0.5 fl. oz. of CM0140968 Surfacer Colorant per gallon of CM0481968 Primer base. Add the colorant to the base prior to admixing. Post adding the colorant to existing mixed material is also acceptable.

    Equipment

    This product can be applied using conventional air spray HVLP, Graco electrostatic air-spray or air-assisted airless. Please consult your Sherwin-Williams representative for specific equipment settings.

    Electrostatic users: Ensure that the aircraft is properly grounded for potential static buildup.

    Primer Application

    Best spray application results are obtained by applying one light continuous closed film cross coat. The recommended dry film thickness is 0.6 – 1.2 mils (15-30 microns).

    1. Make sure pots, guns, and lines are purged and cleaned.
    2. Mix thoroughly and filter strain before spray applying.
    3. Equipment Settings (i.e. Conventional settings):
      Spray atomizing pressure: 50-60 psi (3.45-4.15 bar)
      Pot pressure: 10-12 psi (0.69 – 0.83 bar) using a 60’ fluid hose (3/8” diameter)
      Delivery Rate: 8-10 fluid oz (236-295 mL) per minute

    Always air-blow and tack-wipe the surfaces to be painted. Electrostatic users: Ensure that the aircraft is properly grounded for potential static buildup.

    Primer Drying Schedule

    Dry times are based on the dry film thickness of 0.6-1.2 mils (15-30 microns).

    Note: Solvent selection does not effect dry times below.

    Air Dry Times (75°F /25°C and 50% RH)
    To Recoat: 2 hours minimum, 16 hours maxiumum*
    To Lightly Sand: 6 hours minimum
    o DA (Orbital) Sand: 8 hours minimum

    Force Dry (120ºF (50ºC) to sand or apply topcoat
    1 Hour @ temperature

    Note: Force drying the primer longer than 1 hour will require scuff sanding using Red Scotchbrite to obtain good mechanical adhesion

    * If an intermediate primer or topcoat is not applied within 16 hours of primer application, light scuff sanding using P240, P320 paper &/or red abrasive pads will be required for good intercoat adhesion.

    Surfacer Application

    Apply up to 3 wet single pass coats allowing one hour between coats. Total recommended dry film thickness up to 5.0 mils dry (125 microns). It is preferred to allow overnight cure at 77°F/25°C for maximum cure properties. Constant airflow is recommended. Apply the 2nd and 3rd coat that contains CM0140968 Surfacer Colorant.

    NOTE: Application of these product systems requires recommended temperature / humidity conditions and film thickness ranges. The material, hangar, and aircraft skin temperature should be no lower than 55ºF / 13ºC before, during, and after application.

    Surfacer Drying Schedule

    Dry times are based on the dry film thickness of 5.0 mils (125 microns).

    Air Dry Times (75°F / 25°C and 50% RH)
    To Lightly Sand: 8 hours minimum
    To DA (Orbital) Sand: 12 hours minimum

    Force Dry (120ºF (50ºC)
    Two Sand: 4 hours minimum

    Note: Allow a 2 hour flash prior to bake

    Sanding Recommendations

    Mechanical DA (orbital) sanding or hand sanding of this product works well with 240 or 320 grit sandpaper. Proper sanding is the key to good intercoat adhesion and a smooth appearing surface.

    Note: Once sanded, topcoat within 72 hours. If the cured epoxy primer is inadvertently sanded through, a light coat of corrosion primer as a spot repair 0.5mil (12 microns) will be required prior to spraying topcoat. Allow primer to dry a minimum of 1 hour before overcoating.

    Equipment Cleanup

    Use clean Ketone–type solvents such as CM0110308 MEK. Do not allow material to cure inside equipment.

    Shelf Life

    Shelf Life is applicable only for materials stored in unopened and undamaged original factory filled containers.

    Minimum Storage Temp: 40ºF / 4ºC

    Note: Once sanded, topcoat within 72 hours. If the cured epoxy primer is inadvertently sanded through, a light coat of corrosion primer as a spot repair 0.5mil (12 microns) will be required prior to spraying topcoat. Allow primer to dry a minimum of 1 hour before overcoating.

    Equipment Cleanup

    Use clean Ketone–type solvents such as CM0110308 MEK. Do not allow material to cure inside equipment.

    Shelf Life

    Shelf Life is applicable only for materials stored in unopened and undamaged original factory filled containers.

    Equipment

    This product can be applied using conventional air spray HVLP, Graco electrostatic air-spray or air-assisted airless. Please consult your Sherwin-Williams representative for specific equipment settings.

    Electrostatic users: Ensure that the aircraft is properly grounded for potential static buildup.

    Primer Application

    Best spray application results are obtained by applying one light continuous closed film cross coat. The recommended dry film thickness is 0.6 – 1.2 mils (15-30 microns).

    1. Make sure pots, guns, and lines are purged and cleaned.
    2. Mix thoroughly and filter strain before spray applying.
    3. Equipment Settings (i.e. Conventional settings):
      Spray atomizing pressure: 50-60 psi (3.45-4.15 bar)
      Pot pressure: 10-12 psi (0.69 – 0.83 bar) using a 60’ fluid hose (3/8” diameter)
      Delivery Rate: 8-10 fluid oz (236-295 mL) per minute

    Always air-blow and tack-wipe the surfaces to be painted. Electrostatic users: Ensure that the aircraft is properly grounded for potential static buildup.

    Sanding Recommendations

    Mechanical DA (orbital) sanding or hand sanding of this product works well with 240 or 320 grit sandpaper. Proper sanding is the key to good intercoat adhesion and a smooth appearing surface.

    Note: Once sanded, topcoat within 72 hours. If the cured epoxy primer is inadvertently sanded through, a light coat of corrosion primer as a spot repair 0.5mil (12 microns) will be required prior to spraying topcoat. Allow primer to dry a minimum of 1 hour before overcoating.

    Equipment Cleanup

    Use clean Ketone–type solvents such as CM0110308 MEK. Do not allow material to cure inside equipment.

    Shelf Life

    Shelf Life is applicable only for materials stored in unopened and undamaged original factory filled containers.

    Application Instructions

    Surface Preparation

    To insure proper primer adhesion to the substrate, all substrate to be prepared, different methods should be used. There are a variety of processes to prepare these substrates for primer and painting.

    Sherwin-Williams primers are designed to go over various treatments (i.e., alclad or anodized aluminum, composite, fiberglass, magnesium, and stainless steel). Please refer to recommendations for cleaning, application, and preparation before painting to the manufacturer of the treatment.

    If a wash primer is needed, please refer to the Product Data Sheet for CM0484684 Wash Primer.

    Mixing Instructions

    Shake primer component for 15 minutes before admixing.

    Admix by Volume:
    4 Parts Epoxy Primer CM0481968
    1 Part Epoxy Adduct CM0120828

    Add the Adduct into the Primer Component, stir thoroughly.

    Thinning Instructions

    It is recommended to filter strain admixed and reduced primer before placing material in containers for spraying.

    Guidecoat Colorant to Assist in Sanding (Optional)

    To create color contrast when sanding, add up to 0.5 fl. oz. of CM0140968 Surfacer Colorant per gallon of CM0481968 Primer base. Add the colorant to the base prior to admixing. Post adding the colorant to existing mixed material is also acceptable.

    Equipment

    This product can be applied using conventional air spray HVLP, Graco electrostatic air-spray or air-assisted airless. Please consult your Sherwin-Williams representative for specific equipment settings.

    Electrostatic users: Ensure that the aircraft is properly grounded for potential static buildup.

    Primer Application

    Best spray application results are obtained by applying one light continuous closed film cross coat. The recommended dry film thickness is 0.6 – 1.2 mils (15-30 microns).

    1. Make sure pots, guns, and lines are purged and cleaned.
    2. Mix thoroughly and filter strain before spray applying.
    3. Equipment Settings (i.e. Conventional settings):
      Spray atomizing pressure: 50-60 psi (3.45-4.15 bar)
      Pot pressure: 10-12 psi (0.69 – 0.83 bar) using a 60’ fluid hose (3/8” diameter)
      Delivery Rate: 8-10 fluid oz (236-295 mL) per minute

    Always air-blow and tack-wipe the surfaces to be painted. Electrostatic users: Ensure that the aircraft is properly grounded for potential static buildup.

    Primer Drying Schedule

    Dry times are based on the dry film thickness of 0.6-1.2 mils (15-30 microns).

    Note: Solvent selection does not effect dry times below.

    Air Dry Times (75°F /25°C and 50% RH)
    To Recoat: 2 hours minimum, 16 hours maxiumum*
    To Lightly Sand: 6 hours minimum
    o DA (Orbital) Sand: 8 hours minimum

    Force Dry (120ºF (50ºC) to sand or apply topcoat
    1 Hour @ temperature

    Note: Force drying the primer longer than 1 hour will require scuff sanding using Red Scotchbrite to obtain good mechanical adhesion

    * If an intermediate primer or topcoat is not applied within 16 hours of primer application, light scuff sanding using P240, P320 paper &/or red abrasive pads will be required for good intercoat adhesion.

    Surfacer Application

    Apply up to 3 wet single pass coats allowing one hour between coats. Total recommended dry film thickness up to 5.0 mils dry (125 microns). It is preferred to allow overnight cure at 77°F/25°C for maximum cure properties. Constant airflow is recommended. Apply the 2nd and 3rd coat that contains CM0140968 Surfacer Colorant.

    NOTE: Application of these product systems requires recommended temperature / humidity conditions and film thickness ranges. The material, hangar, and aircraft skin temperature should be no lower than 55ºF / 13ºC before, during, and after application.
