BOSLAI Metal Roof Waterproof Coating is made from silicone-modified pure acrylic emulsion, fumed silica, titanium dioxide filler, and microporous insulation technology. This coating not only provides waterproofing, anti-corrosion, and anti-rust functions but also quickly dissipates heat from the substrate, reducing indoor temperatures. It can be exposed to sunlight for extended periods, with excellent weather resistance and UV resistance.

FAQ
Q: Does BOSLAI metal roof coating prevent rust and corrosion?
Yes. The coating contains anti-corrosion and anti-rust additives that form a dense protective membrane over the metal surface, blocking moisture and oxygen. For best results, wire-brush loose rust particles before application.
Q: Does metal roof coating hold up in extreme weather — coastal, tropical, or freezing climates?
Yes. BOSLAI metal roof coating resists UV, acid rain, salt spray, and extreme temperatures. No cracking at -10°C, stable up to +80°C. Suitable for coastal, tropical, and temperate zones alike.
Q: What colors and packaging options are available?
White and light colors for maximum heat reflection. Custom colors available (reflectivity may vary). Packaging: 18kg or 20kg or 50kg pails. Full OEM — custom brand, label, and packaging — available for distributors.
Q: How to find a reliable metal roof coating supplier worldwide?
Check for: (1) TDS available before ordering, (2) dedicated waterproofing manufacturer, not a general trader, (3) anti-corrosion additives included, (4) heat-reflective technology if energy savings matter, (5) OEM capability for your brand. BOSLAI meets all five — TDS downloadable, sample support available, OEM customized.
