Characteristics and applications:
RPF resin series are products of esterification of rosin
with pentaerythritol. Provide excellent storage stability, heat
oxidation resistance and light color. Dissolve in ester,ketone,
aromatic hydrocarbon. Because of their good mutual-dissolvability
with EVA, SIS, SBS, SBR, NC, they can increase initial adhesive
strength of various kinds of adhesive. RPF resin series are
excellent adhesion resins.
