K-FLEX® 850S

K-FLEX® 850S by LANXESS (previously Emerald Kalama Chemical) is non-phthalate, low-VOC plasticizer. It is a blend of dipropylene glycol dibenzoate and diethylene glycol dibenzoate. It achieves excellent performance and compatibility in waterborne adhesives, latex caulks, and polysulfide & reactive sealants, including acrylic, VAE, PVAc, STPE, and STPU type chemistries. It is suitable for food contact- and pressure sensitive adhesives. K-FLEX® 850S provides excellent performance properties, such as wet tack, extended open times, chalk point/Tg suppression, reduced set times, and strong viscosity response of the base emulsion to the plasticizer (demonstrating compatibility and allowing flexibility). It is optimized for performance, compatibility and economy in waterborne latex applications. It is very effective for hot melt adhesives and putty. It is a viable option for food packaging adhesives. It is label-free grade. It is listed in FDA 21 CFR 175.105- adhesives (part 175- indirect food additives and Subpart B-Substance for use only as components of adhesives).
