Acrynax 11891


ACRYNAX 11891 is a permanently tacky, 100% solid acrylic polymer designed for use as a hot melt pressure sensitive adhesive. It can also be used as a specialty additive to improve the performance of other commercially available hot melt adhesives by enhancing tack and flexibility. This product exhibits good adhesion to a variety of materials including polyester, glass, steel, aluminum, vinyl, fabric, non-wovens and paper. ACRYNAX 11891 provides the lowest peel and tack adhesion but the highest cohesive shear strength in the product line. ACRYNAX 11891 is a thermoplastic polymer which can be applied using a variety of hot melt coating equipment. This polymer may be used as is, or modified with compatible plasticizers, such as rosin based, hydrocarbon, or terpene-phenolic resins.
