HD-2107 DMM can be used as a sole vehicle or blended with acrylic emulsions for spray or rotogravure applications. Rheology modifications can be made with associative thickeners for alternative application methods.
The addition of coalescing solvent is recommended to achieve optimal film formation with HD-2107 DMM. In ambient-cured systems the addition of 5 – 10 % DPnB 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 produce optimal film properties.
