Antitack NP-97/TY-40 is a highly concentrated dispersion of zinc stearates. By means of new technologies and high quality raw materials the zinc stearate content could be increased to more than 40%.

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, calendared sheets, extruded profiles and molding blanks.

For many years zinc stearate dispersions made by Kettlitz-Chemie have been approved. Also Antitack MP-97/TY-40 has no negative influence on the curing properties. During vulcanization, above approx. 120 °C, the stearate particles melt and penetrate into the rubber compound. This avoids the rubber being burnt onto foams, molds and vulcanizate surfaces; welding and bonding with other materials is possible without any problems.

By using a very fine grained zinc stearate, optimizing the sedimentation and foaming behavior, this antitack agent is recommended for application in dipping and spraying equipment.

Antitack NP-97/TY-40 can easily be diluted, even in cold water. For first trials a dilution ratio of 1:20 should be selected.
