Omyabond 120 by Omya is a low-moisture, ultrafine, natural calcium carbonate filler designed for reactive adhesives and sealants. It is a treated mineral with a high surface area. It can be used as a single component to provide a typical rheological modifier profile combined with true reinforcing properties without compromising on moisture content and moisture pick-up. Shows sag resistance, good extrusion rate, good adhesion, higher strength, elongation, good mechanical performance, elastic recovery, and good workability. Provides low energy intensity and easy-to-disperse, cost-effective grade with low polymer content. Omyabond 120 allows moisture scavenging, process savings to avoid pre-drying and higher machine productivity. It is recommended for use in SMP (Silyl Modified Polymer) systems. It enables formulation of sealants that meet the relevant ISO standards while reducing polymer content and without impacting processing.

Omyabond 420 by Omya is an ultrafine, ground calcium carbonate (GCC) filler. It exhibits excellent bond strength and mechanical properties. It offers improved storage stability, workability and ridge holding along with best cost/performance ratio. Due to its smaller particle size, Omyabond 420 provides shear thinning and excellent adhesion on wood. It is designed for moisture curing parquet adhesives such as silyl modified polymers (SMP), hybrid, silicone and polyurethanes. It does not influence viscosity upon accelerated storage, even without pre-drying the formulation.
