Zinc Stearate E-25 is 25% dispersion of zinc stearates. It is used in 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 moulding blanks.

Zinc Stearate E-25 has no negative influence on the curing properties.Durding vulcanization above or approximately 120 ˚C , the zinc stearate particles melt and penetrate into rubber compound. This avoids the rubber being burnt into forms, moulds and vulcanization surfaces,  welding and bonding with other material is possible without any problems.

Zinc Stearate E-25 should be diluted to 2-3% by cold water.
