Mechanical Performance 

High filler levels of up to 60% can be realized (for example in sealants), thus allowing savings on polymers, usually the performance but also cost driver. To maintain the mechanical requirements a careful choice of fillers is necessary. Particle size and distribution has a major influence on bond strength and modulus.

Effect of Surface Treatment
Natural Calcium Carbonates are hydrophilic. For use in polymeric systems we can modify the surface to become hydrophobic. These grades we call ‘treated’ (T) grades.

Whether you are looking for anti-sagging properties and/ or good workability, the particle size distribution of the filler is a key property to influence these requirements. Generally the finer the particles the higher is the influence on the rheological performance.

Strong Bonds - Performance Calcium Carbonates for Adhesives & Sealants

Besides Natural Ground Calcium Carbonates Omya offers also precipitated and modified versions of this versatile mineral. From coarse to fine, treated and untreated, the desired functionality is key for the choice of the most suitable grade.

Most Omya products are manufactured and supplied locally in order to minimize your logistic cost. Our specialties are produced at selected sites and shipped regionally or even globally.

Sustainability at Omya

In 2015, the world leaders adopted the 2030 agenda for sustainable development with 17 sustainable development goals and 169 associated targets. For Omya, the SDG’s are a drive to direct our sustainability efforts.

Low Carbon Footprint

Ground Calcium Carbonate is a natural mineral that has a lower carbon footprint than for example the polymers in use. Using filler improves your environmental footprint.

Take for example parquet adhesives. With the combination of ultrafine and coarser fillers you can achieve the rheological and mechanical performance needed at low polymer contents which is typically the cost driver in a formulation.

Our Calcium Carbonates are alternatives to mineral fillers & pigments with high oil absorption.

Typically, the finer the particle size the higher the oil absorption.

Our Calcium Carbonates with their low abrasiveness improve the workability of adhesives & sealants, leading to an increased work life of application tools and less energy consumption in automatized application processes.

Our low moisture Calcium Carbonates are ready to use: no filler pre-drying, low temperature mixing, reduced cooling times bring along high production capacity and lower energy cost: produce at low temperature to shorten mixing and cooling times (for example from 160 to 15 min).
