Firestop Transparent Wooden Coating V5T
Firestop Transparent Wooden Coating V5T is a dual-component, acid-curable MF resin system enhanced with liquid polyphosphate technology. It combines exceptional transparency with highly effective fire protection for wooden substrates. Upon exposure to fire, the coating rapidly expands to form a stable char layer, providing both aesthetic preservation and enhanced structural safety for the wood substrate.
