Sartomer's acrylated amines are alternatives to free amine synergists in UV- and EB-curable inks and coatings that provide faster surface cure speeds, lower volatility, yellowing resistance and solvent resistance.
We developed our acrylated amines because conventional free amine synergists present a number of formulating concerns. The odor associated with free amines can be a problem before, during and after UV curing. Blooming of the free amines to the surface may result in a grease-like surface film. These conventional amine synergists may also be a source of extractables in cured coatings.
Our acrylated amines enable formulators to achieve performance properties, such as:
- Good adhesion
- Good flexibility
- High reactivity
- Lower film extractables
- Low odor
- Low pigment bleeding
- Low viscosity
- Lower VOC formulations, which do not result in blooming
- Lower volatility
