Applications
Calcium Stearate can be used as a waterproofing agent for fabrics; it can also be used as a lubricant in pencils and crayons and in the dry drawing method of wire production. The concrete industry uses calcium stearate for efflorescense control of cementitious products used in the production of concrete masonry units i.e. paver and block, as well as waterproofing In paper production, calcium stearate is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard making. In plastics, it can act as an acid scavenger or neutralizer at concentrations up to 1000ppm, a lubricant and a release agent. It may be used in plastic colarant concentrates to improve pigment wetting. In rigid PVC, it can accelerate fusion, improve flow, and reduce die swell. Calcium stearate is a component in some types of defoamers.
