Applicable Base Polymer Properties

SEBS rubber is an elastomeric block copolymer that can be used in a wide variety of construction adhesives and sealants. The final adhesive / sealant product can be applied in several different forms. It is used widely as a hot melt, solvent solution, and as a gun-dispensable sealant. Kraton MD6392 is a high vinyl content triblock SEBS copolymer. It is also suitable as an ingredient in formulating compounds for footwear applications and may be used in formulating adhesives, sealants, and coatings.

Resulting Properties

A typical solvent borne SEBS compound has the composition as shown above. SEBS adhesives and sealants are known for excellent adhesion to most substrates and good water resistance. The polymeric compositions along with the other additives will affect both the application and the ultimate performance properties of the joint.

This formulation has the following characteristics:

Lower cost
Low temperature flexibility
Excellent durability and water resistance
Good package stability and adhesion
Will withstand cyclic joint movement
