Compatibility and Solubility
Compatible with vegetable oils, tall oil alkyd resins, hydrocarbonaceous resins and other rosin based resins. It has partial solubility in mineral oils, soluble in aromatic solvents (Toluene, Xylene) and partial solubility in aliphatic solvents (Gas-naphtha, gas solvent). This resin is insoluble in alcohols.
The large contact surface the pieces of resin present make them susceptible to gradual oxidation, which can be more advanced in some batches than others. This can cause darkening and/or affect the resin’s solubility in organic solvents. Therefore, we strongly recommend keeping strict control of inventories at all times, and taking special care to ensure that the oldest material is used first. We suggest a shelf life of 1 year for this product.
