Cray Valley Poly bd® 700S Epoxidized Hydroxyl Terminated Polybutadiene Resin
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Description: Polybd® 700S is a multifunctional, hydroxyl terminated, epoxidized resin offering the compounder a variety of functionalities for formulating finished products. The 700S resin brings hydrophobicity, flexibility, and water resistance to urethane applications. In addition, oxirane oxygen groups on the polymer backbone allow it to be used as the sole resin in epoxy formulations or in combination with bisphenol A or cycloaliphatic epoxy resin formulations. Polybd® 700S resin may be used as a reactive oligomeric additive in cationically cured coatings to impart high flexibility and impact resistance. The epoxy groups will cure with Lewis acids or anhydrides; however, primary and secondary amines are not recommended as curing agents. Product Highlights / Performance Properties: UV cationic curable Epoxy flexibilizer Water resistance Adhesion to a variety of substrates Suggested Applications: Adhesives and sealants Electrical potting and encapsulation Polymer modification Coatings Information provided by Cray Valley
