Free radical curing: There are times that a converter may desire to modify its chemistry for improving:

Coatability / Surface smoothness / Cost of the release coating

Normally a silicone release coating consists of 3 – 4 components. Anchorage component, release component, photoinitiator and a sliding component if required. Our system consists of 2 components. A polymer and release component:

Polymer (contains photoinitiator) = 50 – 75% and Siliconacrylat = 50% – 25%

By changing the ratio of the component’s the anti adhesive properties can adjusted from easy to tight release. Next to the physical improvements significant cost reductions are feasible. These blends are coater- friendly, providing ease of application and consistent coverage onto paper and film. By curing under nitrogen inerting the complete cross linking of all components are ensured.

Cationic curing: 2 – component release coating’s based upon a cationic photoiinitiator. Curing inhibition through substrate or contamination are part of the nature of cationic curing. No nitrogen inerting necessary. We offer also free- radical primer suitable in combination with cationic release coatings to ensure trouble free curing.
