Fire-Retardant Varnish – Woodlac

WOODLAC® is a water-based, transparent, two-component, intumescent fire-resistant varnish. When exposed to heat, it swells to form a carbonized layer. This layer protects the underlying surface from heat and oxygen, thereby delaying the heating and subsequent ignition of the wood substrate.

This product is used on surfaces such as wood, bamboo, and rattan, and in interior decoration, garden structures, and household goods. It’s also utilized for the preservation of historical building surfaces and in wooden architecture with high fire risk.
