Antitack NP-97/TY-40 has no negative influence on the curing properties. During vulcanization, above approx. 120 °C, the zinc stearate particles melt and penetrate into the rubber compound. This avoids the rubber being burnt onto forms, molds and vulcanizate surfaces; welding and bonding with other material is pos-sible without any problems.

- Uses
By using a very fine grained zinc stearate, optimizing the sedimentation and foaming behavior, this anti-tack agent is recommended for application in dipping and spraying equipment. Antitack NP-97/TY-40 mainly is used in the rubber industry to prevent surface sticking of uncured rubber compounds. It is especially suited for the treatment of rubber sheets and strips, granules, calendered sheets, extruded profiles and molding blanks.
