Compatibility and Solubility
Pentalyn™ 670-M resin is compatible with acrylic resins and SS Nitrocellulose. It is incompatible with polyamides. This resin is soluble in alcohols (Ethyl, Isopropyl, etc., partially soluble in aromatic solvents (Toluene, Xylene) and insoluble in aliphatic solvents (Gas naphtha, gas solvent). Pentalyn™ 670-M resin is also soluble in diethylenglycol.

Storage
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.
