Wesocon® L 7634-4
Additive for improving cationic bitumen emulsions

Aqueous dispersion of styrene-butadiene-copolymer dispersions with high solids

Application

Wesocon® L 7634-4 will be used to improve cationic bitumen emulsions for treating surfaces in road construction. Wesocon® L 7634-4 can be used with all common methods of application in cold bitumen processes.

Even when it is cold, the film is characterised by very high flexibility as well as good water resistance. Due to the polymerizate's tendency to crystallise, the polymer film has very good strength while being able to stretch and so displays high elasticity.

Adding Wesocon® L 7634-4 to bitumen emulsions increases their strength, toughness and ductility as well as the softening point, low-temperature flexibility and resistance to aging.

This product can also be used as binder for different other applications.

In case of specific problems and for the preparation of standard recipes, please contact our Sales Division or our Customer Engineering/Applications Divisions.

Safety
Please consult the safety data sheets before use.
