Polyurea elastomer is a compound formed by the reaction of isocyanate component (component a) and amino compound component (component R). 

Spray polyurea elastomer (SPUA) technology is a new solvent-free and pollution-free green construction technology developed to meet the needs of environmental protection after (pollution-free) coating technologies such as high solid coating, water-based coating, radiation curing coating and powder coating in recent 20 years.
