2. Purpose
Used in intumescent paint
(1) Due to its extremely low water solubility, this product is especially suitable for use as an acid source for intumescent coatings. Intumescent coatings on steel structures can meet the fire protection rating of DIN4102; it can also be used as intumescent coatings on wood or plastic.
(2) When used in adhesives and sealants, 15-20% of APP can show good flame retardancy.
(3) It is a very suitable halogen-free flame retardant for polyurethane foam.
(4) Apply to fiber substrate (such as: paper, wood products), epoxy resin or unsaturated resin and other thermosetting resins.
3. Packaging, transportation and storage
Packing: plastic inner woven bag, net weight 25kg.
Transportation: This product is non-hazardous. Prevent moisture, rain and packaging damage during transportation.
Storage: Store in a dry and ventilated warehouse.
