Moisture-curing adhesives Engineered mineral solutions
Imerys engineered minerals are solutions of choice for one-component (1C) "outside-to-inside" moisture-cured adhesives and sealants used for difficult-to-bond substrates such as metals, plastics, etc.
We offer specific product solutions to suit each type of one-component moisture-cure chemistry: silicone, polyurethane, polysulfide and hybrid polymer systems.
High-performance silicone sealants
Imerys supplies calcium carbonate and kaolin products for silicone sealants depending on targeted properties in terms of extrusion rate and mechanical properties.
- ImerSeal™ – engineered, high-end, surface-treated ground calcium carbonates combining the right rheology with low moisture content in a highly dispersible product
- Socal® – ultrafine coated precipitated calcium carbonate (PCC) conferring the right balance of extrusion rate and mechanical properties at high incorporation throughput
Customized solutions for polyurethane
Imerys ground calcium carbonates (GCC), calcined kaolins and wollastonites are effective solutions for polyurethane based moisture-curing adhesives.
We recommend the following ranges:
- ImerSeal™ –GCCs with optimized level of coating, including low-moisture content grades to decrease moisture scavenger content
- ImerCarb™ and PolCarb™ cost-effective (un)coated GCC
- Polestar® – calcined kaolin provides the correct ratio between viscosity and reinforcement
- Nyglos® - acicular shaped wollastonite improve cohesion properties
Polysulfide adhesives
Imerys engineered coated ground calcium carbonate solutions for polysulfide adhesives include:
- ImerSeal™ – coated GCC with optimized level of coating including low particle size grades to boost mechanical properties
- ImerCarb™ and PolCarb™ cost-effective (un)coated GCC
Hybrid polymer adhesives
We supply a wide portfolio of calcium carbonate products for improving the properties of silane-terminated polymer adhesives and sealant formulations.
Adhesives
Our PolCarb™ and ImerCarb™ cost-effective GCC products are specifically recommended for providing correct viscosity and mechanical properties in parquet flooring hybrid polymer adhesives.
Our premium ImerSeal™ surface-coated GCC grades provide low moisture content, viscosity and adhesion in roofing adhesives used for EPDM and concrete bonding.
Our Socal® and Winnofil® coated PCC grades provide the right rheology and reinforcement in hybrid elastic load-bearing adhesives.
Sealants
Low modulus:
- ImerSeal™ coated grades provide ease of use and improved storage stability
- ImerSeal™ 50S grade provide the best storage stability on the market
Medium modulus:
- Socal® PCC grades provide low moisture content and excellent storage stability
- Winnofil® PCC grades boost tensile strength
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.
