Foster® Sealfas® 30-36 HF™ Coating is a halogen-free, white, fire-resistive, tough, washable, abrasion-resistant, indoor coating for thermal insulation. It is also used as a lagging and lap adhesive for canvas and glass lagging cloth. It has excellent brushing characteristics, which will result in better coverage and more uniformly coated surfaces. It presents a neat white finish and will not yellow or become discolored with age. The surface can be washed free of grease, oil, soot and other dirt accumulation.
