Bollom Intulac™ Ultra Varnish Base Coat is a high performance fire protection coating for interior wood surfaces. Use with a protective Intulac™ Satin or Matt Finish Top Coat to complete the protective coating system. The Bollom Intulac™ Ultra Varnish system provides a high performance fire protection coating system for interior wood surfaces. It comprises a clear, transparent, water-based intumescent base coat – designed to form a protective carbon char in the event of fire, delaying the inflammation of the wood – and a clear, transparent, solvent-based protective top coat (available in Matt and Satin finishes). Intulac™ Ultra Base Coat is designed to form a protective carbon char in the event of fire, delaying the inflammation of the wood. It reduces ignitability of soft and hard wood and other wood derivatives I.e. plywood, chipboard, fibre insulation board, hard board and also on veneering (less than or equal to 12mm thick). It also insulates against heat, checks fire, prevents propagation of fire and diminishes flue-gas density and flue-gas temperature.
