General
EFKA® PB 2770 is a silicone-free deaerator and defoamer for UV-curable formulations, composites, gel coats, cast resins and adhesives. The product provides an outstanding compatibility. It is recommended for use in clear and pigmented radiation curable formulations (e.g. overprint varnishes, UV inkjet) as well as for solvent-free unsaturated polyester systems and for pultrusion applications with acrylic, unsaturated polyester and vinylester resins. It is silicone-free and therefore provides excellent recoatability.
