Eastman Kristalex™ 3085 Hydrocarbon Resin
Categories:	Other Engineering Material
Material Notes:	Product Description: Kristalex™ 3085 hydrocarbon resin is a water clear, highly color stable, nonpolar, low molecular weight thermoplastic polymer. This resin is compatible with a wide variety of oils, waxes, alkyds, plastics, and elastomers, and is soluble in many common organic solvents. It is indicated for use in plastics modification, adhesives, coatings, sealants, and caulks. In EVA-based hot melt adhesives, Kristalex™ 3085 is compatible with EVA grades with up to 30% vinyl acetate and is useful in formulating low-color adhesives with good low temperature properties. In styrenic block copolymer based adhesives, Kristalex™ 3085 preferentially associates with the styrenic endblocks, producing lower melt viscosity while maintaining room-temperature cohesion without affecting tack and adhesion properties. Application/Uses: Alluminum-pigment preparations Assembly Automotive Building and Construction Caulks and Sealants Hot Melt Adhesives Laminating Nonwovens Pressure sensitive adhesives Rubber and Plastic Modification Solventborne Adhesives Tapes and Labels Key Attributes: Excellent thermal stability Intermediate softening point Made from purified aromatic monomers Water-white initial color Information provided by Eastman
