Rosin DP 70 is a rubber resin with a very low tendency towards crystallization, obtained from Elliottii pine.
Due to its excellent No Crystallization and low color conditions,
ROSIN NON CRYSTAL is used in depilatory waxes, and as taquifier in some hot melt and water based adhesives. It also finds application in paper sizing, rubber compounds, and road marking paints. We suggest performing tests to determine the proper 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.
18 months from manufacture date, in original unopened packaging.
