Description
TACKWHITE SB4 is a water-based pressure sensitive adhesive, based on anionic dispersion of carboxylated-modified SBR latex and water tackifiers (rosin esters), properly stabilized.
TACKWHITE SB4 has very good stability when stored at temperature between + 10°C and + 40°. It allows to obtain very good p.s.a. articles, being stabilized with very good antioxidants.
However, containing rubber based latices, it produces opaque and slightly yellowish films.
Application
Permanent paper labels, self adhesive fabrics, synthetic and natural leathers, paper boards, polyurethane and polyethylene foams, double sided adhesives etc.
