Baypren 321 Polychloroprene Bayer Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE >> Solvent based ADHESIVE >> Solvent based >> Contact adhesive Poly-2-chlorobutadiene-1,3 Baypren 321 is a thiuram-modified chloroprene rubber with a high rate of crystallisation which gives solutions of medium viscosity. Modification with thiuram yields very good processing properties and compatibility with other adhesive components. Adhesives formulated with Baypren 321 set rapidly and form bonds of very high strength. Flat chips, powdered with talc to maintain the free-flowing properties (powder content max. 1 %). Baypren 321 is suitable for use in the formulation of contact adhesives for many applications including the manufacture and repair of footwear, processing wood and plastics and laying floor coverings. polychloroprene for the production of adhesives with a long open time and high initial strength. Poly-2-chlorobutadiene-1,3. Thiuram-modified polychloroprene rubber with a high rate of crystallisation. Can be used for the production of solventborne contact adhesives. Provides a long open time, high initial strength and good processing properties. Provides a long open time, high initial strength and good processing properties. Gives solutions with medium viscosity. Not modified with sulphur or thiuram.
