Q1: What is the primary function of SILRES BS Powder A in coating formulations?
A: SILRES BS Powder A functions as a hydrophobicity-enhancing and surface-modifying additive, improving water repellency, dust resistance, and substrate adhesion—particularly in mineral-based coatings such as plasters, renders, and cementitious systems.
Q2: How is SILRES BS Powder A incorporated into aqueous systems?
A: It is typically dispersed directly into the aqueous phase during the initial mixing stage, often before adding fillers or binders. Efficient dispersion may be achieved using low-shear stirring; high-shear homogenization is generally not required due to its free-flowing powder morphology and optimized wettability.
Q3: Is SILRES BS Powder A compatible with common inorganic binders like Portland cement or lime?
A: Yes—it is specifically designed for compatibility with alkaline inorganic matrices, including Portland cement, hydrated lime, and gypsum. Its silicone resin structure remains stable under typical pH conditions encountered in these systems during processing and early curing.
Q4: Does SILRES BS Powder A affect the mechanical strength or vapor permeability of treated substrates?
A: When used at recommended dosage levels, it preserves the inherent breathability (water vapor transmission) of mineral substrates while minimally influencing compressive or flexural strength—its mode of action is primarily surface-directed rather than bulk-modifying.
