Q1: What is the primary function of DOWSIL OFX-0400 Silicone Oil in industrial formulations?
A: DOWSIL OFX-0400 is a low-viscosity, non-reactive silicone fluid designed primarily as a surface modifier and processing aid. It imparts lubricity, improves substrate wetting, reduces surface tension, and helps suppress foam in demanding industrial applications such as coatings, adhesives, and sealants.
Q2: Is DOWSIL OFX-0400 compatible with water-based systems?
A: Yes — DOWSIL OFX-0400 is formulated to be readily dispersible in aqueous systems, especially when used with appropriate emulsifiers or surfactants. It is commonly incorporated into waterborne paints, architectural coatings, and cleaning formulations to enhance leveling and reduce defects.
Q3: How does DOWSIL OFX-0400 differ from reactive silicone fluids like silane- or siloxane-functional types?
A: Unlike reactive silicones, DOWSIL OFX-0400 is non-functional and chemically inert under typical processing conditions. It provides temporary, physical effects—such as slip and surface migration—without participating in crosslinking reactions, making it suitable for applications where long-term stability and predictable performance are required without curing interference.
Q4: What are typical dosage ranges for DOWSIL OFX-0400 in finished products?
A: Dosage depends on formulation requirements and desired performance, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—based on total formulation mass. Optimization is recommended through lab-scale testing to balance efficacy, compatibility, and cost-effectiveness.
