- Applied Product Data
Hardness - Forms a tough, resilient, abrasion-resistant film.; Water Vapor Permeability - Cures to form a solvent vapor resistant film. Water vapor permeability is approximately 0.03 Perm Inches.; Weatherability - Poor. Do not expose to strong sunlight for more than two weeks.; Chemical Resistance - Good solvent, acid, alkali and salt resistance. Does not have inhibitive properties.
- Packaged Product Data
Flammability - The dry film will support combustion unless applied to a non-flammable substrate. Fire-rated systems (ASTM E-108 or UL 790) are not affected when a specified amount of coatings are applied over GacoFlex U5677.; Toxicity - Contains perchloroethylene which requires ventilation during application. Contains less than 2% polymeric isocyanate which may be irritating to the skin and is toxic if inhaled as particulate matter. Any material contacting the skin should be neutralized by washing with generous quantities of water. Spray application can lead to inhalation of particulate matter and solvents; consequently, a respirator is required for spray application.; Adhesion - Excellent adhesion to metals, wood, concrete, masonry and most coating and plastic materials.; Cleaner - Clean equipment with GacoFlex T5130 thinner and cleaner.
