Question 1

What is the correct application method for CR-Cement as a contact adhesive?

Accepted Answer

Apply a thin, even coat to both substrates by brush or spray. Allow to flash off for 3–8 min until the surface is touch-dry but still tacky. Then bring both surfaces into firm contact under hand or roller pressure. Bond forms instantly. For maximum strength, press at 0.2–0.4 MPa for 10–30 seconds.

Question 2

Is CR-Cement the same product as the Contact Adhesive Base (Neoprene Solution)?

Accepted Answer

Both are polychloroprene (CAS 9010-98-4) based, but CR-Cement has lower solid content (15–22% vs 20–25%) and a lower viscosity, making it suited for spray application and thin-film bonding of foam and fabric. The higher-solids neoprene base is formulated for thicker-film structural applications such as leather and rubber-to-metal bonding.
