Wacker to show coating compounds at Labelexpo Europe

Due to their high reactivity, the silicone polymers require very little catalyst to cure fully. Compared to conventional coating systems, platinum savings of up to 60 per cent are possible with the Dehesive SFX system. This makes production considerably more cost-effective for release-paper and label manufacturers. In addition, the properties of the new silicone polymers can be optimized specifically for fast labelling processes, according to a press release.

Due to high reactivity, coating systems based on Dehesive SFX are ideal for use in high-speed coating equipment. Even at low catalyst dosage, they yield a fully cured silicone layer. The resulting release properties are ideal for machine delamination at high throughputs. Due to the flat release force profile, very little force is required for delamination even when labels are removed very quickly – such as during mass production of consumer goods.

The new star polymers are tailored to high-speed applications and differ in the number of branches, vinyl content and viscosity. The curing rate, release force profile and coverage of the substrate surface can be specifically adjusted to customers' requirements. (GK)
