Veradel® 3600RP hydroxyl-functionalized polyethersulfone (r-PESU) is an amorphous, high-temperature sulfone polymer featuring reactive end groups to enhance solubility for dissolving or dispersing into solutions and to improve adhesion to substrates when used as a coating.
Veradel® 3600RP r-PESU offers excellent toughness and outstanding hydrolytic resistance. It resists attack from steam, boiling water and mineral acids. Cast films or coatings or r-PESU are transparent and have additional desirable properties, including long term thermal stability, excellent metal adhesion and formability and inherent flame resistance.
Veradel® r-PESU polymers are available in two molecular weight regimes. Veradel® 3000RP is a high molecular weight sulfone polymer with a relatively low level of functionality while Veradel® 3600RP has a lower molecular weight sulfone polymer (approximately half the molecular weight of the Veradel® 3000RP) with roughly 3-5 times higher level of functionality. The differences in molecular weights results in highly varied levels of viscosity, when measured under similar conditions.
Typical applications includes high-temperature coating formulations and specialty adhesives.
All Veradel® r-PESU polymers are produced at Solvay's state-of-the-art , world-scale facility in Panoli, India under ISO 9001:2000 and ISO 14001:2004 certified quality management systems.
