Sealant strips and other Chemistries

Imerys supplies a wide range of mineral solutions suitable for improving the properties of hotmelts, butyl / EPDM sealant strips, solvent based adhesives and bitumen membranes.

Imerys minerals: 

  • Improve sandability due to their natural softness
  • Improve adhesion
  • Enhance elasticity and cracking resistance
  • Improve rheology
  • Improve storage stability
  • Make spreading easier
  • Extend pot life
  • Are natural, environmentally friendly solutions

Sealant strips

Our PolCarb, ImerCarb ground calcium carbonates (GCC) are cost-effective extender solutions for butyl / EPDM sealant strips.

Hotmelt adhesives

Our PolCarb ground calcium carbonate (GCC) grades are cost-effective solutions, prized for the low decantation properties they confer to hotmelt adhesives.

Butyl mastics

We recommend our cost-effective PolCarb® GCC range and Luzenac soft talc solutions for butyl mastics.

Luzenac is particularly recommended for its anti-scratch properties in IG glazing primary seals.

Bitumen membranes

Bitumen is an effective glue and unlike most glues is 100% waterproof.  Bituminous membranes are perfect for waterproofing roofs, basements, below ground structures, bridges and other structures.

We recommend our Suzorite® micas which provide superior oil absorption and sound damping in bitumen membranes.

Joint compounds

Our Suzorite®, MU and WG mica ranges provide excellent anti-mudcracking and barrier properties.

WG high aspect ratio micas also confer superior whiteness.

Solvent-based adhesives

Our ImerSeal 96S and ImerSeal 94S grades are effective rheology modifiers in solvent-based adhesives. 

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.
