MICRO-ULTRA 15-3 set fast filler paste is a rigid, light weight (low density) system meeting FAR 25.853a for the stringent requirements of
the aerospace and aircraft industries. New technology and space age materials have made possible a weight reduction in applied product
of 30-35%. It is an ideal material for repair and surface finishing of interior composites that is qualified to several OEM specifications *. The
chemical resistance of MICRO-ULTRA 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. MICRO-ULTRA 15-3 has excellent bonding and filling qualities with fiberglass,
SMC, BMC, RIM, FRP, graphite and Kevlar
composites. It withstands vibrations and impact without loss of bond or surface webbing.
MICRO-ULTRA 15-3 can be applied by splining, squeegee, spatula or any flat type tool. Once set, it can 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 prepreg 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.
