REYDER EG 115 is a high-boiling point ester resin from gum rosin, disproportionated and deodorized, with excellent thermal stability.


Due to its high thermal stability and softening point, REYDER EG 115 is indicated as taquifier for hot-melt adhesives (Non-woven, Tapes, Labels, Construction). It is suggested to perform tests to determine the most appropriate quantity to be used for each specific case.


Excellent compatibility with solvents (Alcohols, aliphatic, naphthenic & aromatics), elastomers (SBS, SIS), copolymers EVA, waxes (paraffinic, Fisher Tropsh; synthetic), and other typical components of hot melt and water based adhesives.
