Introducing our high-quality Fumed Silica, specifically designed for professionals working with FRP (Fiber Reinforced Plastics) and Gelcoats. This versatile product offers exceptional reinforcement and thickening properties, making it an indispensable tool for achieving superior performance and durability in your projects. Our Fumed Silica enhances the mechanical strength, impact resistance, and overall stability of FRP composites and Gelcoats, ensuring a long-lasting and reliable end result. With its fine particle size and excellent dispersion characteristics, it is easy to incorporate into your formulations, providing you with precise control over viscosity and rheology. Trust our Fumed Silica to elevate the quality and performance of your FRP and Gelcoat applications.
Hydrophilic Description:
Fumed silica is a kind of Amorphous Fumed Silica Powder. In the production process of FRP, unsaturated polyester resin is an important part of FRP. Our silica helps control the viscosity of FRP and achieve the desired thixotropy and is also an indispensable and efficient thickener.
Many yacht hull shells, decks and interior components are now composed of molded fiberglass with a gel coat. Using this gel coat layer to spray patterns not only protects the aesthetic appearance of FRP products, but is also essential for regular maintenance. Therefore, the vast majority of yachts now use gel coats, which are mainly convenient and easy to maintain. Our silica helps control the thixotropy required in the gel coat manufacturing process and is an integral and efficient thickener.
The benefits for Fiber Reinforced Polymer(FRP) and Gelcoat
Optimal rheological control for ideal viscosity
Prevents solids from precipitating in the resin
Gel-like resin thins when sheared for easy processing
