Nitro Quick-drying primer for FRP is a single-component volatile self-drying primer for FRP. It uses nitrocellulose as the main film-forming substance and is designed for FRP/FRP. The formula is optimized for the characteristics of the base material of glass fiber reinforced plastics, adding special adhesion promoters, sealing fillers and anti-rust additives, without the need for curing agents and baking. The core value is to quickly prime, enhance the adhesion between FRP and nitrocellulose topcoats, seal surface defects of the substrate, and provide a smooth and solid transition base for the nitrocellulose topcoat on the surface of FRP. Core features: Adaptable to fiberglass, strong adhesion; extremely fast drying, efficient construction; easy to polish, compatible between layers limitations and adaptations It is only suitable for priming indoor or short-term outdoor fiberglass parts. It has insufficient weather resistance under long-term exposure to sunlight or humid environments. It contains highly volatile solvents and requires enhanced ventilation during construction. It is not suitable for direct use with non-nitrocellulose topcoats such as epoxy and polyurethane. Scope of application FRP products: bottom sealing and leveling of FRP furniture, amusement facilities, sanitary ware, sports equipment, etc. FRP repair: Renovate and prime old FRP parts to quickly repair surface scratches, bubbles and other defects. Composite substrate: The transitional primer between fiberglass and metal composite parts, taking into account the adhesion requirements of the two substrates.
