The challenges for Solventless Thermal silicones to coat PET are many and today can be summarised as follows for the "Clear on Clear/No Label Look" label applications:

    - Good cure and immediate anchorage on non surface treated
      (chemically etc.) PET films

    - With or without corona treatment

    - Anchorage with ageing under difficult storage conditions (vs
      water based adhesives, high humidity, high temperature)

    - Premium Release

    - Modifiable release

    - Low silicone transfer/good final label printability

Bluestar Silicones PET range comprises 3 Silcolease(R) products specifically dedicated to PET film coating:

    * Silcolease(R) POLY 330

    - Excellent anchorage giving possibility to run without anchorage
      additive for many applications. Of great interest for food contact
      labels, medical applications etc.
    - Very Flat release profile
    - Low blocking potential
    - Medium slow speed release
    - Low co-efficient of friction

    * Silcolease(R) POLY 334

    - Flat release profile
    - Easy slow speed release

    * Silcolease(R) ADD 380

    - Additive to maintain good anchorage under difficult ageing
      conditions such as high temperature, humidity and vs. aggressive
      tackified adhesives

Sean Duffy, Global Market Manager for the Silcolease(R) range commented: "These products illustrate our dynamic attitude towards the release coating segment. Thanks to their high performance and Bluestar Silicones' expertise, these products will allow our customers to improve their level of competitiveness: POLY 330 is optimised for anchorage and cure speed and POLY 334 is best suited for lower release requirements. We intend to complement this existing range with new crosslinker and additives from our soon to be launched Optima II range of systems to offer even better performance on PET and other filmic substrates."
