Abstract:
A process for achieving a fire and flame retardant and inhibiting effect on natural, synthetic and metallic substrates comprising the steps of:a) preparing a colloid solvent by dispersing hydroxyethylcellulose water; b) adding to said colloid solvent chemical means to produce a fire and flame retarding and inhibiting colloidal intumescent base; and, c) further adding to said intumescent base chemicals selected from the group consisting of flame spread reduction materials, thermal resistance enhancement materials, thermal transmission reduction materials, flame refraction materials, water resistance materials, elasticity and thickness adding materials, and combinations thereof to produce an intumescent mixture; and, d) stabilizing the resulting intumescent mixture for 2 to 5 days at room temperature prior to step (e); and, e) coating said intumescent mixture onto the substrate.
