L-3528 may be formulated into coatings applied by spray, brush or pad applicator. It can be used as a sole vehicle or blended with acrylic emulsions. The rheology may be modified with associative thickeners.
L-3528 may be air dried, if desired, depending on film thickness. The addition of 5 – 10% coalescing solvent is suggested in ambient temperature drying situations. Typical oven drying temperatures and dwell times for aqueous coatings may be sufficient to produce optimal film properties.
