Processing 

Mixing order:

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

2. Add DEHESIVE® SFX 251 AMA® in several portions and stir slowly until the mixture is homogeneous.

3. Thoroughly stir in crosslinker. 

4. Slowly stir in catalyst. Local over-concentrations must be avoided.


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

Compounded batches may emit small amounts of hydrogen, but only for a short time. Storage in ventilated containers is recommended to avoid pressure formation.

Coating :

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

Storage

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.
