Aromatic Resins
Picco Resins
These products are manufactured using a mixture of petroleum- derived feed streams. Softening points range from 103° to 141°C (217° to 286°F). In general, these products are light amber to dark brown in color. With varying degrees of aromatic content, these resins will find utility in adhesives, rubber compounding, printing inks, coatings, paints, concrete curing, waterproofing, and sealant compounds. They are compatible in useful proportions with styrene-butadiene rubber (SBR), polar elastomers, chlorinated rubber, and chlorinated paraffins. The resins contain an antioxidant.3
General Product Characteristics
These are neutral resins with <1 acid number and <2 saponification number. The relative degree of unsaturation can vary, with bromine numbers ranging from 5 to 20 for Picco 5000 and 6000 series resins. In general, the specific gravity as measured at 25°C (77°F) will be 1.08 to 1.10. Flash points as measured by COC are >232°C (>450°F).
