Structural Adhesives

Structural Adhesives Imerys wollastonite are excellent solutions for reinforcing the mechanical properties of structural adhesives

Structural adhesives or ‘load-bearing’ adhesives need to stand the test of time. Products may undergo shock, vibration, chemical exposure, temperature excursions and many other destructive influences that may weaken systems. 

With their distinctive acicular morphology, wollastonites are excellent solutions for reinforcing the mechanical properties of structural adhesives including epoxies, methacrylates, UV curing adhesives, polyurethanes, and cyanoacrylate adhesives (CAs).

 

Imerys wollastonite:

  • Impart strength and tensile (peel strength)
  • Improve sag resistance
  • Can be used to replace or extend milled or chopped glass fiber

Our wollastonites are suitable for use in:

  • Insulating glass sealants
  • Structural glazing sealants
  • Wet room sealants
  • Construction sealants
  • Flooring adhesives
  • Woodworking adhesives

Our chemically modified grades provide low moisture content and uptake. They have been specifically designed for reactive adhesives and sealants based on a range of polymer systems. 


We recommend our Nyglos®, Nyad® and high aspect ratio Aspect® wollastonites for structural 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.
