Resin P Dimerized rosin Resinas Sintéticas Tackifier >> Rosin ADHESIVE Partially dimerized gum rosin. Used for adhesives, tapes, SBR emulsifying, labels. Obtained through chemical changes in the rosin's molecular structure, the "Resin" group offers the most stability and best properties for your application. This chemical modification can be: hydrogenation, disproportionation and polymerization. Resins obtained from modified rosins exhibit excellent properties due to their high resistance to oxidation. Partially dimerized gum rosin. Used as tackifier for adhesives. Offers stability. Exhibits good properties due to its high resistance to oxidation.
