Welcome to Imerys Performance Minerals


Adhesion Imerys minerals can demonstrate a positive effect on adhesion

In several adhesive and sealant systems, Imerys minerals demonstrate a positive effect on adhesion by taking advantage of unique shape, size distributions and surface chemistry. It seems that use of such minerals tend to allow extension of the resin dispersions and adhesion promoter for optimal effect.

Hydrous and calcined kaolin

Our fine platy particle hydrous kaolins and calcined kaolins provide higher interaction sites for adhesion.  In starch and synthetic resin systems, kaolins improve flow characteristics, penetration, adhesion, and dry time.

We recommend:

  • Polestar 200R 
  • Glomax® LL
  • Polwhite B / E
  • Argirec B24


Calcium silicate chemistry provides higher adhesion to a hydrophilic surface.

We recommend:

  • Nyad® M200
  • Nyglos® 8 (coated) 
  • Wollastocoat®
  • Aspect® 4222 (coated)


A fine particle size and control surface chemistry of calcium carbonate allows efficient use of adhesive promoters which enhance surface to substrate adhesion.

Our premium ImerSeal 36S surface-treated GCC grade confers superior adhesion in hybrid roofing adhesives used for bonding EPDM membranes to concrete substrates, for example.

Our PolCarb grades provide excellent adhesion in dextrin adhesives for paper substrates.



We offer a full range of custom formulation and technical and process support services to help you match the right mineral grade to your application requirement.
