Maxant® PRO is a highly effective silicone antifoam emulsion. It offers excellent foam control and high stability in various foaming systems. Permanent foam cut off Stable effects during storage period Rapid foam knock-down Foam inhibition in extreme temperatures (up to 95 °C) Long term foam inhibition Compatibility with wetting agents Long durability in acidic and alkaline conditions Outstanding durability at low add on levels Maxant® PRO is mainly designed for preventing foam in process applications. For process applications, we recommend prediluting Maxant® PRO silicone antifoam with cold water in a ratio of 1:1 to 1:10.

SURFECO® PLUS is a super-spreading surfactant based on a trisiloxane ethoxylate, a silicone polyether copolymer with 550 molecular weight. SURFECO® PLUS has super-spreading properties in aqueous solutions while remaining stable in formulations from pH 5 - 8. SURFECO® PLUS can reduce surface tension in aqueous solutions at use levels up to 1.0 % by weight. Typical recommended starting level is 0.1 %. Stable effects during storage period Super-spreading and wetting Lowers surface tension more, compared to conventional surfactants Provides an aqueous surface tension of 21.5 nM/m2 Effective and remaining stable in formulations from pH 5 - 8 Low viscosity Very effective at low concentrations SURFECO® PLUS should be added directly into tank and agitated to ensure proper mixing. For optimum performance, solutions containing SURFECO® PLUS should be applied within 72 hours after mixing.
