SILCOLEASE POLY 600 is formulated with addition of a crosslinker, for example SILCOLEASE XL 321, a catalyst, for example SILCOLEASE CATA 340 and if necessary a release control additive, for example SILCOLEASE RCA 12 or SILCOLEASE RCA 395.


Recommended formulation, typical

SILCOLEASE POLY 600: 100 parts

SILCOLEASE XL 321: 5-6 parts

SILCOLEASE CATA 340: 3-5 parts


Bath preparation

It is recommended to add the products in the following order:

SILCOLEASE POLY 600 and SILCOLEASE XL 321. Mix these together thoroughly before finally adding SILCOLEASE CATA 340 and complete the mixing to a fully homogeneous blend.


Warning: SILCOLEASE XL and SILCOLEASE CATA may react violently together and therefore must not be blended together separately from the other components of the system.

SILCOLEASE POLY 600 may be stored at temperatures between -20°C / -4°F and 50°C / 122°F for up to 24 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


SILCOLEASE POLY 600 is a solventless silicone polymer intended for release applications involving papers, plastic films and various substrates.


SILCOLEASE POLY 600 has been designed to give excellent performances on demanding high-speed labelling applications.


Combined with components from the SILCOLEASE OPTIMA range, SILCOLEASE POLY 600 uses lower Pt levels and can be coated at lower temperatures than traditional systems.



Fast cure system offering:

  • Good cure at high coating line speeds.
  • Good anchorage on different substrates.
  • Wide range of release levels with addition of release modifiers.


  • Self-adhesive labels. 
  • Self-adhesive tapes.
  • Low release force liners.
