Description
TACKWHITE A 205 SL is a water borne P.S.A., based on anionic dispersion of natural and synthetic latices (SBR, acrylics) and rosin esters, properly stabilised and thickened.
TACKWHITE A 205 SL has excellent ageing properties and grants very stable P.S.A.. It contains the best available antioxidants, however, being based on SBR latices, it yelds transparent but slightly yellowish films.
The product does not contain organic solvents.
Application
Permanent paper labels; fabrics; synthetic leathers; polyurethane, PE, PVC, PU foams; paper and paperboards; etc., with very high peel adhesion and a good resistance to high warm (until 70°C).

Notes
Formulations based on synthetic latices, once coated, may be subject to a physiological decline of the adhesive performance.
