Characteristics and applications
RGF resin series are produce of esterification of rosin with glycerol. Provide excellent storage stability, heat oxidation resistance and light color. Dissolve in ester , ketone, aromatic hydrocarbon. Mix well with high polymer for NR, CR, SBR, EVA, SIS and SBS. It can increase initial adhesive strength of various kinds of adhesive. RGF resin series are excellent adhesion resins.
