	INTUMESCENT FIREPROOFING
	** NOTE TO SPECIFIER ** A/D Fire Protection Systems; thin-film Intumescent fire resistive coating for interior structural steel. . This section is based on the products of A/D Fire Protection Systems, which is located at: 420 Tapscott Rd. Scarborough, Ontario M1B 1Y4 Te1: (800) 263-4087 Tel: (416) 292-2361 Fax: (416) 298-5887 E-mail: mail@adfire.com Web: www.adfire.com . A/D FIREFILM(r) II is a water based thin-film fire-resistive coating for structural steel at interior locations in buildings. During a fire, it expands to form a meringue-like insulating ash which protects steel from fire. For a decorative, colored surface a top coat of a low volatile organic compound (VOC) silicone alkyd coating is used; available in most colors in gloss and semi gloss finishes. When spray applied (recommended), the overall finish is smooth to slight orange peel. Texture will vary with application technique.
