Tensile Properties
Application
L-2897 may be used as a sole vehicle or blended with acrylic emulsions for spray or brush applications. Rheology modifications can be made with associative thickeners for alternative application methods.
Curing
L-2897 may be dried at ambient temperatures with supplemental co-solvent addition of 5 % DPM or DPnB on total formulation weight. Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
