Description
TACKWHITE A 83 is a low Tg pure Acrylic polymer emulsion that forms extremly clear, elastic and tacky films when dried over 0°C . The dried film has a very aggressive initial tack and a good cohesion.
Application
TACKWHITE A 83 is suitable for the production of pressure sensitive packaging and office tapes on BOPP films. By applying approximately 20-21 g/sqm dry weight, it produces a good balance of peel and shear strength. It is supplied as a ready-to-use emulsion and it is suitable for most of today's modern coating machines. With TACKWHITE A 83 it is possible to produce BOPP tapes with low unwinding noise, by corona treating the backside of film.
Other prerogatives:
- Very aggressive initial tack
- Good adhesivity
- Good properties with low amounts/sqm
