ISO-LITH Paste 3A
Drying agent
ISO-LITH Paste 3A is highly effective drying agent (adsorbents) for plastics, coatings and paint systems. ISO-LITH Paste 3A contain a zeolite mineral with a defined cavity structure (3 Å). Water molecules from the organic bin-ders to be dried, selectively diffuse into the cavities of the synthetically produced material and are bound by adsorption. A typical application is the preparation of polyurethane formulations with ISO-LITH Paste. This reliably prevents the formation of carbon dioxide bubbles when the isocyanate hardener component is added. The paste is stabilised by a mineral anti-settling agent. The product is RoHS compliant according to EU Directives 2011/65/EU (“RoHS”) and 2015/863/EU (“RoHS III”).
Area of application
For non-foaming polyurethane formulations, for casting resins, adhesives and coating materials.
