Application

N/A L-2875 can be used as supplied or blended with acrylic emulsions for spray, dip or rotogravure applications. It can be thickened with associative thickeners for knife-over-roll or similar methods.

Curing

N/A Due to the co-solvent free nature of L-2875, the addition of coalescing solvent is recommended to achieve optimal film formation. In ambient-cured systems the addition of 5 - 10 % coalescing solvent is suggested. Less coalescing solvent is required in heat-cured systems to attain comparable film properties. Typical drying temperatures and dwell times for aqueous coatings are sufficient to optimize film characteristics
