Grade:VF710
Product: High Adhesion Middle Temperature Hot Melt Adhesive Resin 110℃
Resins in Hot Melt Adhesives
Resins are responsible for the tack of the hot melt. Tack is defined as the measure of adhesive stickiness, which is generally the period the adhesive stays intact after its application. In addition, resins are in control of the wetting of an adhesive. This means resins control the period it remains a liquid while the hot melt is in contact with the surface substrate.
Descriptions
VF710 is a maleic anhydride and vinyl acetate functionalized polyethylene mixture, easy to form film, with excellent processability and adhesive strength.
