Kristalex™ 5140 hydrocarbon resin is a high softening point, low molecular weight resin produced by copolymerization of pure aromatic monomers. It is designed primarily for use as a modifier resin in high performance adhesives and coating compositions. In these applications, its water clear color, heat stability, and resistance to oxidation and discoloration are used to advantage. In EVA-based hot melt adhesives, Kristalex™ 5140 is compatible with EVA grades with up to 18% vinyl acetate and is useful in formulating low-color adhesives with improved high temperature resistance. In styrenic block copolymer based adhesives, Kristalex™ 5140 preferentially associates with the styrenic endblocks, producing higher cohesion at temperatures up to 70°C without affecting tack and adhesion properties. Kristalex™ 5140 complies with many FDA regulations for applications involving direct contact with food. Compliance with a given regulation in a specific situation should be verified prior to use in a food contacting application.
