Winlex 4220 Rosin ester Finjetchemical Industries Tackifier >> Rosin ester Acrylics/ Acrylates Rubber - Elastomer (Chloroprene, Butyl …) Ethylene co-terpolymers - solid (EVA, EMA...) SEALANT ADHESIVE >> Hot-melt A modified rosin ester which offers excellent heat and aging stability for use in adhesives. Winlex4220 is a disproportionated rosin ester for adhesives which provides flexibility and impact-resistance, compared to adhesives tackified by C(5) based hydrocarbon resins. Broad Compatibility, Good Specific Adhesion, Super thermal Stability. Soluble in petroleum benzine, mineral spirit, benzene, ethyl acetate,acetone. Insoluble in ethyl alcohol. Compatible with NR,SBR,EVA210 and EVA420. Virtually no skinning/gelling for consistent machine operation, Improved adhesion to a wide variety of substrates, Expanded formulary choices. Use in EVA, SBS, SIS, and other hot melt adhesives; Solvent-born SBR adhesives, Solvent-born natural rubber/SBR adhesives, Solvent-born natural rubber adhesives, Solvent-born Acrylic adhesives; construction adhesives, rubber compounding, sealants, coatings and other applications. Modified rosin ester. Possesses good specific adhesion, thermal stability and broad compatibility (NR, SBR, EVA). Used as a tackifier in adhesives. Provides flexibility, impact-resistance, very good heat and aging stability and improved adhesion to a wide variety of substrates. Application : hot melt adhesives, pressure-sensitive adhesives, solvent-borne natural rubber and/or SBR adhesives, solvent-borne acrylic adhesives, sealants.
