Proposed dosage
CX-235
CX-235 is a polymer-based defoamer, free of silicone, and is used in unsaturated polyester resins. It is applicable to various unsaturated polyester resins and processing methods. It is also particularly suitable for pultrusion processes of acrylic, unsaturated polyester and vinyl ester resins.
Product advantages
CX-235 demonstrates the highest defoaming efficiency in almost all processing methods of unsaturated polyester resins. In some resins, defoaming agents may cause fogging in the finished components. Prevent the mixture of air during the production and application of plastic systems (pultrusion process).
