vip gmbh polyaspartic vs aromatic
DESCRIPTION
1) A polyaspartic is an aliphatic polyurea because it is the reaction of an aliphatic polyisocyanate with a polyaspartic ester - which is an aliphatic diamine. However, polyaspartic coatings are very different in both application and coating performance properties from conventional polyureas.TRANSCRIPT
