Q1: What is the primary function of DOWSIL 2-1912 Silicone Fluid in formulations?
A: DOWSIL 2-1912 is a low-viscosity, reactive silicone fluid designed primarily as a surface modifier and release agent. It imparts lubricity, improves substrate wetting, reduces surface tension, and enhances slip and mar resistance in coatings, inks, adhesives, and sealants.
Q2: Is DOWSIL 2-1912 compatible with common organic solvent-based and waterborne systems?
A: Yes — DOWSIL 2-1912 exhibits broad compatibility with both solvent-borne and waterborne systems, including acrylics, polyurethanes, alkyds, and epoxy resins. In waterborne formulations, it may require mild agitation or pre-dilution to ensure uniform dispersion.
Q3: How is DOWSIL 2-1912 typically incorporated into a formulation?
A: It is generally added during the let-down or post-additive stage under moderate agitation. Due to its reactivity, incorporation at temperatures below 60 °C is recommended to avoid premature interaction with other functional components. Dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight of the total formulation.
Q4: Does DOWSIL 2-1912 provide long-term stability in cured films?
A: Yes — once covalently bonded via its reactive silanol groups during cure or ambient crosslinking, DOWSIL 2-1912 becomes an integral part of the polymer matrix, offering excellent migration resistance and sustained surface performance without bloom or leaching.
