Both Ultra Violet light and Electron Beam curing must be carried out under an oxygen-deficient atmosphere (typically below 100ppm and preferably below 50ppm residual O2). Components should be well mixed before use.

Consult ELKEM Silicones for technical assistance in the selection of appropriate photoinitiators and conditions of irradiation (power, spectrum.etc.) for UV processing.


  • SILCOLEASE UV POLY 111 UV/EB Silicone Polymer:

    Combined with other Silicones from the 100 series enables the controlled increase of the low speed release.  When used on its own or at high levels in combination with SILCOLEASE UV POLY 110, SILCOLEASE UV POLY 111 yields high release values.  When SILCOLEASE UV POLY 111 is used in combination with high levels of SILCOLEASE UV RCA 170, easy release can be achieved. It is also active under EB irradiation.
  • SILCOLEASE UV POLY 110 UV/EB Silicone Polymer:

This acrylate-modified silicone polymer builds the performance architecture of the system and combines fast and complete cure speed with excellent adhesion to substrate liners. Its optimized balance of acrylate functionality and di-methyl silicone sequences provides stable release performance. SILCOLEASE UV POLY 110 can be used in combination with SILCOLEASE UV POLY 111 to produce specific release levels required against the adhesive used.


A "low release modifier" which exhibits outstanding premium release stability against aggressive adhesive materials. This "low release modifier", when blended with SILCOLEASE UV POLY 111 at 30 % to 70% addition level will give an easy release, low percentage (1-10%) addition will allow to avoid potential zipping. It is also active under EB irradiation.

SILCOLEASE UV POLY 111 UV/EB silicone system is a 100% reactive release coating chemistry based on acrylate-modified silicone copolymer technology. Instantaneous and complete cure is achieved by simply passing the coating under either UV light or Electron Beam.

SILCOLEASE UV POLY 111 UV/EB silicone polymer can be used in combination with SILCOLEASE UV POLY 110 as a release control additive or used alone as the polymer in a silicone system. SILCOLEASE UV POLY 111 UV/EB will provide a tight stable release at low speeds against a wide variety of adhesive materials. It can be used in combination with high levels of SILCOLEASE RCA 170 to provide an easy release against a number of substrates.


Due to the sensitivity to oxygen inhibition of the free radical acrylate silicone crosslinking mechanism, cure must be carried out inside a nitrogen-inerted environment.


Functional Fluid

  • Good component compatibility.
  • Very long bath life stability.
  • Room temperature processing which enables coating on thermally sensitive substrates.
  • Instantaneous cure leading to high production line speeds.
  • Acrylate silicone chemistry giving little or no sensitivity to substrate inhibition or high moisture.
  • No need for paper re-moisturisation.
  • Optimized polymer architecture ensuring excellent anchorage to wide range of substrates
  • No back side transfer.
  • Improves the hardness (or friction resistance) of the coating.
  • Excellent subsequent adhesion.


  • Hygienic applications (sanitary napkins, diapers, etc…)
  • Adhesive protectors (labels, tapes etc….)
  • Linerless labels (thermal labels, overprint application…)
