Polytone AP 112 is a
heat reactive alkyl phenolic resin formulated for use in Neoprene rubber
adhesives. It imparts low initial viscosity and viscosity stability to
adhesives
of this type. AP 112 can also be used with the adhesive grades of
chloroprene where good bond strength at room and elevated temperatures are
required.
