Q1: What is the primary function of SILRES BS 710 in coating formulations?
A: SILRES BS 710 acts as a hydrophobicity and durability enhancer in water-based architectural and industrial coatings. It improves water repellency, weather resistance, and substrate adhesion without compromising breathability or film flexibility.
Q2: Is SILRES BS 710 compatible with common waterborne acrylic and styrene-acrylic dispersions?
A: Yes, SILRES BS 710 is formulated for easy incorporation into standard waterborne polymer dispersions. It typically requires no pre-dilution and remains stable under normal formulation pH and shear conditions, though compatibility should be verified during full-scale batch testing.
Q3: How is SILRES BS 710 typically dosed in finished coatings?
A: Dosage depends on the desired performance level and base formulation, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to total formulation solids—to achieve effective surface modification and moisture resistance.
Q4: Does SILRES BS 710 require thermal curing to develop its full functionality?
A: No, SILRES BS 710 undergoes ambient coalescence and gradual crosslinking upon film formation. While elevated temperatures may accelerate network development, full hydrophobic performance is achieved under standard drying conditions typical for waterborne systems.
