Specific features of DEHESIVE® PSA 630 T

  • Solvent-based

DEHESIVE® PSA 630 T can be used for coating of several film-substrates such as Polyester, Polyamide, Polyimide and others substrates for manufacture of different silicone pressure sensitive adhesive tapes and other articles.


DEHESIVE® PSA 630 T can be diluted with aliphatic or aromatic solvent (e.g. toluene, white spirit, naphtha). It is typically blended with addition curing silicone PSA system (e.g. DEHESIVE® PSA 765). For an optimum balance of surface tack, adhesion strength and cohesive strength it is necessary to cure the coated DEHESIVE® PSA 630 T for 1 – 2 min. at 140 – 150°C by using additing DEHESIVE® 765 and catalyst C05 or PT 5. It is recommended to remove the solvent before curing process at 80 – 90 °C for ~0.5 min. Higher temperature can cause incorporation of the solvent into the adhesive film, which can impair the adhesive properties.


The 'Best use before end' date of each batch is shown 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.
