Applications
On account of low water-solubility, SHIAN-APP-II is specially suitable to be used as acid source for intumescent coatings. Intumescent coatings on the steel structure can meet the requirements the DIN4102 fireproofing grade. For polyurethane foams, SHIAN-APP-II is a suitable halogen-free flame retardant. SHIAN-APP-II has an excellent flame retardant effect in the fibre base material such as paper and wood products. Adding 15-20% SHIAN-APP-II to Casting resins based on epoxy resins or unsaturated polyester resins can reach UL 94-V0 grade.
