Description
TACKWHITE A 84 is a water-borne pressure sensitive adhesive, based on acrylic polymer emulsions. It ensures excellent stability to UV light and very good ageing properties.
TACKWHITE A 84 is APEO free and doesn't contain plasticizers.
Application
TACKWHITE A 84 has been specifically designed for the production of outdoor masking tapes. The product is also characterized by very good resistance to high temperature and pressure, as per autoclave sterilization cycles. However, it can be used for any application where very good cohesion and excellent peel adhesion are required: insulating polyurethane, polyethylene, polyamidic foams, fabrics, synthetic and natural leather.
