Product information

Product Name
Synpro® Aluminum Stearate R
Description

Synpro® ALUMINUM STEARATE R is a low-level ash, free flowing, fine powder product primarily for paint / coatings (lacquer and varnish), ink, pigment suspensions, hot melt adhesives, and drilling well mud applications.

Due to its unique distearate formulation, it is a flatting agent in hot melt adhesives, ink, lacquer, and varnish applications. It provides a surface which diffuses incident light creating a flat effect, but is both transparent and waterproof. It can be used as a thickener for paints / coatings, pigment suspensions, greases, and drilling well muds. Additonally, it is an excellent waterproofing agent for masonry (cement) applications and paper coatings.

Synpro® ALUMINUM STEARATE R is suitable for use in food packaging applications in accordance with many FDA Code of Regulations; an updated complete list is available upon request.
