API-BI795

API-BI795 is a blocked urethane pre-polymer that can be defined as an isocyanate reaction product. Is stable at room temperature but dissociates to regenerate isocyanate functionality under the influence of heat. Exhibits excellent wash durability for fluoropolymer treated fabric, long term pot-life in aqueous systems, excellent compatibility due to its non-ionic nature and excellent adhesion to substrates. Shows water and oil repellency performance. Is added directly to waterborne formulations with mild agitation. Temperatures between 120°C and 180°C is used to release the blocking agent to volatilize from the coating and react with other active hydrogen-containing compounds to form more thermally stable urethane or urea linkages. Used in coatings for wood, leather, inks, adhesives, textiles and waterborne coatings for metal.
