Polyurethane Defoamer YRXP-02 is a high-efficiency multi-purpose non-silicon defoamer, which is suitable for anti-foaming both on production process and static, demonstrating high performance in most of systems with small dosage. It is recommended to non-aqueous systems, especially for the systems which the silicon is limited using.
Product Model: YRXP-02
Typical Properties:
Appearance: Colorless transparent liquid
Chroma (APHA): ≤200
Density (g/cm3, 25℃): 0.892
Viscosity (mPa.s, 25℃): 28±10
Solubility: Soluble in normal polyurethane raw materials (polyether polyol, plasticizer)
Applications: YRXP-02 can be widely used in diverse PU CASE applications
Features & Advantage
◆ General-purpose defoamer, to be used in the systems with solvent/non-solvent, filler/non-filler.
◆ Excellent performance of inhibiting and breaking foam, to be suitable for anti-foaming both on production process and static.
◆ Non-silicon content, to be applicable to the systems which the silicon is limited using in particular.
◆ Environmental protection and safety, to be applied to food contact materials.
◆ To be compatible with various systems, be soluble in benzene, toluene, mineral oil and ester solvents.
User's Guide:
? Levels of 0.2-0.5% as supplied by weight on total volume. For high surface tension, systems, the dosage could be up to 1% or even more. Please test to make sure the best dosage.
? Please shake well before using. It can be diluted before using with right solvent/diluent.
? YRXP-02 may result in slight fogging and reducing transparency in some systems. Please test before using in case of high transparency requirement.
