HERCULES alpha-Pinene

HERCULES a tha-pilieiie is a clear, water-ndiite product otNaiiied by fractional distiiration of, steam-distilled wood onpentine. It consists predominantiy of the bicydic tetpeoe hydrocarbon, alpha-pinene. Hercules alpha-pinene can be used wherever a higb-purity-gtade alpha-pinene is required. 

water-white, high purity, chemically reactive, excellent solvent, narrow distallation range.

Terpene-based resins are obtained from turpentine sulfate, a byproduct of the paper industry, and from limonene, a product of the citrus industry. Products obtained are alpha-pinene, beta-pinene, and dipentene. The alpha-pinenes are apparently the preferred product for hot melt adhesives as they are the most compatible with EVA copolymers. Adhesives compounded with dipentenes have excellent color and thermal stability, odor, oxidation resistance and hot tack properties. Typical of the products available in this class are the Piccolyte series of resins (Hercules). Limonene-based products are exemplified by Zonatac 105 (Arizona Chemicals).
