Two-Component PU System for Dry Laminating Adhesive

VAROSIVE VD-3000R/30H System is a alcohol dilutable two component polyurethane
adhesive with many advantage over conventional urethane/isocyanate adhesive.
It is suitable for food packaging and has good adhesion, high initial tack and good
chemical resistance.

1. Characteristic of VD-3000R/30H

Alcohol Solvent

VD-3000R/30H is supplied in alcohol and is diluted with alcihol or alcohol/water mixture.
No expensive urethane grade solvents are required, nor is there a pollution problem.

Wide substrate choice

VD-3000R/30H is recommended cellulose, PE, PP, Nylon films and paper ; it gives excellent
clarity on PVDC coated films, high initial tack and good chemical resistance.

Easy Storage

VD-3000R/30H contains no free isocyanate. There is no reaction with moisture in the air
neither is there a potential health hazard.
It therefore has good shelf life, and opened drums may be easily stored in the factory.

Easy Mixing

VD-3000R/30H has a non-critical mixing ratio, which allows small errors in mixing on the
factory floor. The adhesive ready for use has an excellent pot life, which reduce waste and saves money.
