This product is approved for Class 1A coatings in a wide range of coating weights. Heavy coating weights should be avoided for Class 3.
MIL-DTL-81706A describes a strip-and-weigh coating weight determination method. The following table offers some guidance in obtaining the proper coating weight range and estimates expected coverage area per pen (with a second coat applied over the first dry coat).
Light Coating Weight:
Class 1A and 3. Felt tip damp. Wet film appearance similar to a common felt-tipped type marker. Expected coating weight range is 13 – 18 mg/ft2. Dried appearance is nearly colorless. Expected coverage per pen is approximately 50 ft2.
Moderate Coating Weight:
Class 1A and 3. Felt tip moderately wet. Wet film appearance is heavy, but would not sag if held at a 90 degree angle. Expected coating weight range is 18 – 22 mg/ft2. Expected coverage per pen is approximately 35 ft2.
Heavy Coating Weight:
Class 1A ONLY. Felt tip very wet. Wet film appearance is very heavy and would sag and possibly drip if held at a 90 degree angle. Expected coating weight range is 22 – 35mg/ft2. Expected coverage per pen is approximately 25 ft2. If the coating puddles or tends to run, an excessive coating weight may be obtained. Be especially aware of depressions on the surface where excessive treatment solution could collect.
For economy and quality, the operator should be trained to keep the tip fairly moist- but not saturated with the treatment solution.
Proper Application and Use Procedure of ALODINE 1132 Touch-N-Prep Pen per MIL-DTL-81706, Class 1A and Class 3, Form VI, Method D for Aluminum and Aluminum Alloys Only.
