DEHESIVE® 920

DEHESIVE® 920 is a solvent-free, addition-curing silicone fluid. It is part of a multicomponent system. Combined with crosslinker, catalyst and others it is used to apply a release coating on paper and filmic substrates. 


特性

  • Rapid curing
  • Low release force at low peel speed
  • Dynamically raising RF profile;
  • In-line processing possible
  • Suitable for versatile PSA adhesives
  • Very low volatiles content
  • Very long pot life

DEHESIVE® 920 is part of a release coating system for paper and filmic substrates.

 

Processing: 

 

DEHESIVE® 920 is used in combination with crosslinker and platinum catalyst and if applicable CRA® release modifier.

Mixing order

1. First pour in CRA® modifier in case CRA® is used.

2. Add  DEHESIVE® 920 in several portions and stir slowly until the mixture is homogeneous.

3. Thoroughly stir in crosslinker homogenously. 

4. Slowly stir in catalyst homogenously and avoid local over concentrations.


Make sure that catalyst poisons are avoided in batch preparation and processing steps. 

For a short time compounded batches may emit small amounts of hydrogen. To avoid pressure formation store in ventilated containers.
 

Coating :

Modern coating systems are particularly effective with DEHESIVE® systems. The batch is best added directly to the nip of the coating unit.

储存

Store in a Dry and Cool place.
The 'Best use before end' date of each batch is printed on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
