SIOResin® has introduced WRS-1002, a next-generation water-based intumescent fireproof resin
with an outstanding 100x expansion rate, exceptional transparency, and environmentally friendly
composition, this innovative formulation is tailored for manufacturers developing transparent fire-
retardant coatings for wood materials, notes a press communiqué.
SIOResin® WRS-1002 is engineered to provide exceptional flame resistance and thermal insulation.
When exposed to heat, the resin rapidly carbonizes and expands, forming a thick insulating layer
that effectively blocks oxygen and heat from reaching the substrate. This intumescent reaction is the
key to its superior fireproof performance, allowing coated surfaces to withstand extreme
temperatures and delay combustion.
With an expansion rate exceeding 100 times, WRS-1002 ensures comprehensive fire protection
while maintaining a clear and smooth surface finish. Unlike traditional fireproof coatings, which
often compromise aesthetics, this advanced resin allows for decorative transparency, making it ideal
for wood coatings where natural grain visibility is desired.
A major advantage of WRS-1002 is its simple and adaptable formulation, making it highly accessible
for coating manufacturers looking to develop fire-retardant paints with minimal adjustments. The
resin features include room temperature curing for convenient application; low viscosity with high
solid content, ensuring smooth blending and application; and excellent compatibility with common
coating additives and binders.
