Phenolic Resin 551 is a heat reactive,alkyl phenolic resin formulated for use in Polychlo- roprene based contact adhesives.It imparts low initial viscosity and excellent viscosi- ty-stability to adhesives of this type.Phenolic Resin 551 can also beused with the adhe- sive grades of chloroprene where good bond strength,both at room and elevated temperatures.

SOLUBILITY
Phenolic Resin 551 is soluble in aromatic and aliphatic hydrocarbons,esters,ketones, and partially soluble in higher alcohols.
APPLICATION:
The primaryfunction of Phenolic Resin 551in polychloroprene contact adhesives is to impart low initial viscosity and maintain viscosity stability.Adhesives of this type depend on an interaction oftheelastomer and metal oxides for the developmentof their high co- hesive strength at room and elevated temperatures.In adhesives based on polychloro-prene,551 gives good bond strength,both at room and elevated temperatures.
STORAGE:
For best results, Phenolic Resin 551 should be stored wheretemperatures do not exceed 869F for extended periods of time.Aswith all phenolic resins,Phenolic Resin 551 will
become darker with age.
