Flame-Retardant Polyester Filler/Flaring Paste from SkyGeek offers protection against the types of damage caused by high-heat exposure. Whether you’re worried about fire or an overworked engine, micro-ultra composite filler can help deliver the protection you need at an affordable price. The rigid, lightweight (low density) system acts as a fire retardant. It is classified as "NO BURN" for the stringent requirements of the aerospace and aircraft industries. It is made using the latest technologies and space age materials, resulting in a weight reduction in applied material of 30-35 percent. Adtech Micro-Ultra 15-3 is an ideal material for repair and surface finishing of interior composites when OEM regulations must be complied with. The chemical resistance of P-15-3 is excellent; the system will withstand the cleaning solutions used in routine maintenance. Micro-Ultra 15-3 offers the user a smooth, creamy system with high physical properties and less added weight. Micro-Ultra 15-3 is non-conductive and has excellent finishing properties. It also has excellent bonding and filling qualities with fiberglass, SMC, BMC, RIM, FRP, graphite and Kevlar™ composites. Once applied, the filler/flaring paste will easily withstand vibrations and impact without a loss of bond or surface webbing. Micro-Ultra 15-3 can be applied by splining, squeegee, spatula or any flat type tool. Once applied, it should be smoothed and allowed to set. After the material is cured, it may be finished by mechanical or hand sanding or grinding. Decorative coverings are also workable; Micro-Ultra 15-3 does not bleed out. Typical applications include: Filling porosity and cloth impression in composites, filling porosity and surface blemishes on exterior composites, surface filling on interior composites, renewing and repairing broken or cracked areas, overhaul and refinishing on interior parts, many more areas of final fabrication and finish.
