Cray Valley has introduced new Wingtack STS aromatically modified C5 resin. This hydrocarbon resin is designed for improved compatibility and performance with low-cost SBS block co-polymers. According to the company, Wingtack STS, when used in butadiene-based elastomers, offers extremely low odor and excellent compatibility with polar elastomers. Wingtack STS also provides lower melt viscosities than typical SBS systems. Applications for this modified resin include, pressure sensitive and hot-melt adhesives. More info: Cray Valley.
