Aqueous dispersion of copolymer of butyl acrylate and methacrylic acid.

Application area:

Glutinous dispersion for obtaining a sticky layer on polypropylene and polyethylene films, PET and other substrates (production of adhesive tapes, self-adhesive labels, noise-, sound-, vibration-proof materials, etc.)

Product properties:

- high peeling and shearing adhesion;

- Long-term stickiness, which allows you to repeatedly duplicate the materials to be glued.
