At Labelexpo Americas 2014, Bluestar Silicones unveiled Silcolease Poly 356, an ultra-flat release coating system which targets low platinum, solventless systems and is said to help label manufacturers enhance productivity and realise significant cost savings.
An innovative silicone release coating which provides premium flat release over a broad range of strip speeds, Silcolease Poly 356 is claimed to offer "the flattest release profile in the industry" and enable label manufacturers to increase converting speeds. It is designed for formulation flexibility to allow reduction in platinum catalyst and more cost-effective process conditions for pressure-sensitive applications.
The new coating is said to provide good cures at high coating line speeds, effective cure on thermally sensitive substrates, and a wide range of release levels with the addition of release modifiers. It anchors to most substrates and "has excellent bath stability".
Bluestar has also introduced two new UV photoinitiators. Silcolease UV CATA 243 is a next-generation cationic photoinitiator which requires lower addition levels and is more effective than current products. Silcolease UV CATA 102 is for free radical UV curing of silicone acrylate release coatings.
