Acrylated Amine Synergists for Faster Cure Speeds

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
