Silcolease® UV POLY 204 must be used with a Cationic photoinitiator as a catalyst, for example Silcolease® UV CATA 211, and if necessary a release control additive, for example Silcolease® UV RCA 251 or RCA 200.
Silcolease® UV POLY 204 is commonly used as a viscosity modifier in conjunction with a second base polymer, for example Silcolease® UV POLY 200.
Recommended formulation, typical:
Silcolease® UV POLY 200 (or 215)...................... 100 - x parts
Silcolease® UV POLY 204………………...................... x parts
Silcolease® UV CATA 211 .......................................1 - 4 parts
Recommended bath preparation procedure:
The components should be added to the bath whilst constantly stirring in the following order: Silcolease® UV POLY 204, then Silcolease® UV CATA 211 and then if required the release control additive Silcolease® UV RCA 251 or RCA 200.
When used as a viscosity modifier Silcolease® UV POLY 204 should be mixed with the appropriate polymer (for example Silcolease® UV POLY 200 or Silcolease® UV POLY 215) and then Silcolease® UV CATA 211 and other components as indicated above.
|SILCOLEASE UV POLY 204 may be stored for up to 24 months from its date of manufacturing.||Please consult the Safety Data Sheet of this product.||Heavy Metals|
SILCOLEASE UV POLY 204
Silcolease® UV POLY 204 is a 100% reactive release coating chemistry based on epoxy silicone copolymer technology. In combination with the patented Iodonium Borate UV photoinitiator technology it offers a highly reactive system with excellent anchorage on difficult low surface energy filmic substrates.
Whilst the polymer can be used alone it is most commonly used as a viscosity reduction additive for the polymers UV POLY 200 or UV POLY 215.
- Very low viscosity, UV system diluent
- Excellent anchorage, especially to untreated polyester films
- Very low extractable silicone
- Excellent subsequent adhesion
- Differential release (release level modifiable up or down)
A UV curing silicone release coating on films & papers-tight release base polymer for :
- Self adhesive labels
- Tapes (2 sided adhesive tapes)
- Industrial (bitumen, floor tiles)
- Hygiene (sanitary towels, diapers)
- Other self-adhesive protectors (envelopes, personal care)
