▶ Product Description
Piccotex LC hydrocarbon resin a the medium softening point member of in a series of highly stable, thermoplastic materials based on purified aromatic monomers with a slightly broader color specification than other Piccotex products. These resins have outstanding hot tack; heat sealability; resistance to discoloration; acid, alkali, and moisture resistance; and stability to elevated temperatures encountered in compounding. High initial and retained gloss, and improved application speeds on curtain coating and roll coating equipment. Piccotex LC complies with some FDA regulations for applications involving direct contact with food. Compliance with a given regulation in a specific situation should be verified prior to use in a food contacting application.

▶ Compatibility and Solubility
Compatible in useful proportions with paraffin, chlorinated paraffin, microcrystalline waxes, low molecular weight polyethylenes, high styrene resins, vinyl toluene polymers, ethylene-vinyl acetate (EVA) copolymers, and many common plasticizers. Soluble in aliphatic, aromatic, and chlorinated hydrocarbons; ethers; esters; nitroparaffins; and benzyl alcohol. Insoluble in lower alcohols, glycols, and water. For low or zero VOC systems Piccotex LC is soluble in the VOC exempt solvents t-butyl acetate and perchlorobenzenetetrafluoride (PCBTF) and will tolerate some acetone and/or methyl acetate as a diluent in solvent systems based on TBA and/or PCBTF. VOC exemptions and environmental regulations vary regionally and compliance with local standards should be verified before any claims about VOC content are made.
▶ Packaging
Pastilles, in multi-wall paper bags (50 lbs, 22.7 kgnet wt).
