Application

N/A Spray or pad solids may be adjusted for optimum add-on. Rheology may be modified with associative thickeners for knife coating applications.

Curing

N/A L-2961 will form a film at ambient temperatures. Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
