Company Info

Basic Info

This nano silica transparent high-temperature resistant varnish is a professional transparent thermal protection coating developed for glass, ceramic, metal and other transparent or light-colored surface high-temperature protection scenarios. It adds nano silica sol and modified acrylic resin, forming a transparent and dense protective layer after curing, which can effectively resist high-temperature oxidation and corrosion without affecting the original color and transparency of the substrate. It is suitable for high-temperature glass equipment, ceramic crafts and other scenarios that require transparent surface protection, improving the service life of the substrate while maintaining the aesthetic appearance of the product. It meets the environmental protection requirements of low VOC content, and is suitable for professional surface treatment of high-end handicrafts, electronic equipment and industrial transparent components.

Customer reviews

Michael · Aerospace Engineer
The nano-silica transparent high-temperature resistant varnish has been a game-changer for our aerospace components. It maintains excellent clarity even after prolonged exposure to 800°C, which is crucial for our inspection windows. The application process was smooth, and the cured coating shows remarkable resistance to thermal cycling. We've observed no cracking or yellowing after 50+ cycles, outperforming our previous coating solution by at least 30% in durability tests.

Product Description

Product features:

This product has three core advantages. First, it uses nano silica composite modified acrylic resin as the base material, which has excellent high-temperature stability up to 400℃, and will not yellow or lose transparency after long-term high-temperature exposure, maintaining the original aesthetic effect of the substrate. Second, it has a light transmittance of more than 92% at 550nm, which will not affect the light transmittance and visual effect of transparent substrates such as glass and ceramics. Third, it has excellent weather resistance and corrosion resistance, solving the pain points of ordinary transparent coatings that are prone to yellowing, cracking and peeling under high-temperature and ultraviolet radiation. It can also form a scratch-resistant protective layer on the surface of the substrate, improving the wear resistance of the substrate surface.
