Tris(2-butoxyethyl) Phosphate (CAS 78-51-3) is an alkyl phosphate plasticizer and flame retardant that appears as a clear, colorless to very slightly yellow liquid, improves low-temperature flexibility in PVC and NBR, reduces plastisol viscosity, and acts as a defoaming and coalescing aid in water-based coatings and polishes. It appears as a clear, low-viscosity liquid with excellent compatibility in various polymers.
This Technical Grade additive is specifically designed to improve the low-temperature flexibility of resins. It also functions as a powerful defoaming agent in aqueous systems like floor polishes and paints.
TBEP is valued for its ability to reduce the viscosity of plastisols while providing fire-retardant properties. It is a versatile solvent and coalescing aid in the production of high-gloss coatings.
