SHB-301 is a fire-resistant, rubberized coating that is an effective barrier for heat and sound, and provides long-term weatherability. Originally designed for engine rooms in large marine vessels, it contains noise and heat in intense areas, and prevents such disturbances from travelling throughout.

SHB-301 has high tensile strength providing tenacious adhesion to almost any substrate. And its fire resistant qualities immediately extinguish itself once the source of the fire has been removed. SHB-301 is a waterproofing sealant that's also abrasion-resistant. It's available in dark gray; however, it may be top coated with Flex Thermacoat for added insulation and bright white appearance. SHB-301 is lead-free and contains non-hazardous ingredients which doesn't produce harmful fumes or odors.

SHB-301 Application

SHB-301 may be applied by brush, roller or low pressure airless sprayers. When applying multiple coats allow some drying time between coats. SHB-301 cures via air drying and at 77°F and 50% RH the coating will be dry to the touch in about 30 minutes. The curing process continues over 48 hours to achieve optimal properties. The surface to be coated should be clean and free of grease, oils and other debris. Do not apply at temperatures below 50°F or above 90°F, or if rain or heavy dew is imminent. Avoid heavy buildup, puddling, and overlapping.

SHB 301 Coverage

Coverage per gallon will be dependent on the porosity of the surface the coating is being applied to and the ultimate dry lm thickness desired. In general, SHB-301 should yield on average about 100 square feet per gallon at 6 mil DFT. SHB-301 is formulated to protect against staining from oil, grease, fuels, and other spills and prevents and inhibits the formation and growth of mold, mildew and algae.

SHB 301 Cleanup

Clean spills and spatters immediately with clean water. Clean hands and tools immediately after use to prevent the coating from setting up as the dry coating will be dicult to remove. If the application is via spraying, ush spray equipment with sucient amount of clean water to prevent any residue SHB-301 staying in the system and clogging up the mechanism.
