Polyurethane Defoamer YRXP-02S 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-02S

Applications: YRXP-02S 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.
◆ To be compatible with various systems, be soluble in benzene, toluene, mineral oil and ester solvents.
User's Guide:
▶According to the different amounts of foaming substances contained in different application systems, the general addition amount is 0.1% -0.5%, and the optimal amount should be determined through small-scale experiments.
▶The different powder fillers in the formula may affect the defoaming effect of YRXP-02S, and the defoaming effect of the polyurethane system without powder is very efficient.
▶ Please shake well before using. It can be diluted before using with right solvent/diluent.
▶ YRXP-02S may result in slight fogging and reducing transparency in some systems. Please test before using in case of high transparency requirement.
