A-C 400

A-C performance additives for hot melt pressure-sensitive adhesives

Ethylene vinyl acetate (EVA) copolymer in prill form, with a VA content of 13%, used extensively in hot melt adhesives (HMAs) to control rheology and boost adhesion. It can be added as a diluent but provides the dual function of reducing application viscosity at melt, while providing an adhesion boost versus homopolymer, non functional diluents (FT, byproduct, thermally degraded (TD) and PE homopolymer waxes). It is completely miscible in EVA adhesive resins, as would be expected by the similar chemistry. It is also used in candles to provide paraffin crystal nucleation, which increases thermal and breakage resistance, adhesion to glass, and fragrance retention.

BENEFITS:

• Reduced oil migration
• 7% increased peel and shear strength
