Laurex
Zinc salts of lauric and related fatty acids
Chemturaï

Sp.gr. 1.18; tan flaked solid; mp about 107-118°C, but not definitely specified; good storage stability.

For CR, NBR, NR, SBR and their latices; recommended for tire carcass and tread compounds, extruded stocks, proof goods; activates thiazole accelerators and their derivatives; evens out and advances curing rates of off-grade rubbers deficient in natural fatty acids. Low blooming from cured and uncured compounds; much less blooming than many other fatty acid softeners; non-discoloring; melts, disperses readily.
