Description
TACKWHITE SB4 E is a water-borne pressure sensitive adhesive, based on an anionic dispersion of carboxy-modified SBR latices and water tackifiers (rosin esters), properly stabilized. It yields excellent p.s.a. articles, being stabilized with high performance antioxidants.
However, containing rubber based latices, the film will be slightly yellowish.
Application
Permanent paper labels, self adhesive fabrics, synthetic and natural leathers, paper boards, polyurethane and polyethylene foams, double sided adhesives etc.
