Reswax [Borden], TM for a series of wax-resin blends used as coatings and hot-melt adhesives in paper conversion. The polymers used include butyl rubber, polyisobutylene, chlorinated rubber, polyethylene, and styrene copolymers. 

Since a great deal of butyl and polyisobutylene is used to modify wax, and since the technique to make wax blends is quite sensitive, it deserves special mention. If PIB is used, it is placed in a kneader and allowed to work until it attains a maximum surface area. This is often termed vicing, since PIB at this stage looks like cooked rice. The wax is slowly added to this deed rubber. It is especially important that the quantitites of wax added, especially initially, be quite small and that the mix be allowed to become homogeneous before more wax is added. Butyl rubber will tend to band rather than rice in a kneader, but the same slow initial wax addition procedure must be followed.
