Q1: What is the primary function of SILIKATE TES 28 in coating formulations?
A: SILIKATE TES 28 functions as a hydrophobic, heat-resistant silicone resin modifier that enhances weather resistance, water repellency, and surface durability—particularly in mineral-based coatings such as silicate paints and plasters.
Q2: Is SILIKATE TES 28 compatible with alkaline systems like potassium silicate binders?
A: Yes, it is specifically designed for compatibility with high-pH silicate systems and remains stable under alkaline conditions typical of mineral paint formulations.
Q3: How is SILIKATE TES 28 typically incorporated into a formulation?
A: It is generally added during the late-stage mixing phase, either as a pre-diluted dispersion or directly under moderate shear, and does not require catalysts or high-temperature curing to achieve functional performance.
Q4: Does SILIKATE TES 28 contribute to film formation or act solely as an additive?
A: It participates in co-film formation with inorganic binders, improving cohesion and reducing micro-cracking—rather than forming an independent organic film—and supports long-term integrity without compromising vapor permeability.
