Pentaerythritol Rosin Ester using gum rosin from pine tree as its raw material， by added Pentaerythritol and other auxiliary materials ，its acid value is well be decreased ，it also shows a better water resistance ，and not metal corroding compare to the gum rosin。It has the characteristics of low acid value, high hardness and high melting point. It is widely used in hot melt adhesive, pressure melt adhesive, shoe glue, film glue, sealant, coating, paint, ink, etc Soluble in aromatic and aliphatic hydrocarbon solvents(petroleum benzine, mineral spirit, benzene, ethyl acetate, acetone),esters, ketones and chlorinated solvents. Insoluble in alcohol and water. Compatible with Ethylene Vinyl Acetate (EVA) polymers, Ethylene Ethyl Acrylate, Styrene-Isoprene-Styrene (SIS), Styrene- Butadiene-Styrene (SBS), SBR, natural rubber, butyl rubber, neoprene, acrylic, LMW polyethylene, amorphous polypropylene and other polymers and with phthalate and polyester plasticizers, alkyds, hydrocarbon resins and terpene resins.
SUGGESTED APPLICATIONS 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.
