Лако-красочные материалы — производство

The use of polyurethanes in the pressure-sensitive adhesives market has been relatively small. Polyurethanes have been somewhat limited to being used as additives to pressure — sensitive adhesives to improve their cohesive strength. Recent developments in the institu­tional carpet backing or automotive carpet floor mat markets suggest that pressure — sensitive urethanes can succeed commercially [89].

IX. SUMMARY

Polyurethane adhesives as a class can no longer be perceived as new raw materials. From a base of 217 million pounds, double-digit growth can no longer be expected. Even so, significant growth will continue. Formulators are taking advantage of the tremendous flexibility of urethane chemistry in designing new adhesive products. Specialty niches such as waterbornes and reactive hot melts, for example, will continue to emerge and fuel growth. Exciting times lie ahead for innovative formulators of polyurethane adhesives!
