Polyurethane spraying raw materials are mainly composed of isocyanates and polyether polyols. These two raw materials in the foaming agent, catalyst, flame retardant and other additives, through the role of special equipment mixing, by high-pressure spraying site foaming and become a polymer.
Polyurea spraying raw material is a special material used for spraying polyurea elastomer. Polyurea is a class of compounds generated by the reaction of isocyanate components with amino compounds. This material has high solid content, does not contain any volatile organic compounds (VOC), and is friendly to the environment.
