Eastman Poly-Pale™ Partially Dimerized Rosin
Categories:	Polymer
Material Notes:	Product Description: Poly-Pale™ resin is a pale, partially polymerized (dimerized) rosin. Compared with pale grades of regular wood, gum, or tall oil rosins, it has a higher softening point, higher viscosity (molten and in solution), much greater resistance to oxidation, and complete freedom from crystallizing when in solid form or in solution. Its many uses include the preparation of varnishes, driers, synthetic resins, ink vehicles, floor tile, rubber compounds, solder fluxes, and various adhesives and protective coatings. Application/Uses: Assembly Bookbinding Caulks and Sealants Contact Adhesives Footwear and Leather Hot Melt Adhesives Laminating Nonwovens Packaging Pressure sensitive adhesives Solventborne Adhesives Tapes and Labels Wax Modification Wire and Cable Key Attributes: Alcohol-soluble High softening point Non-crystalline Resistant to oxidation Thermoplastic rosin acid Information provided by Eastman
