Rayven Release TestingOffers Complete Solutions
Some of our release testing machines will give us graphical output plots.
The testing of release liners utilizes a standard test tape. Rayven commonly use Tessa 7475 tape (lot number controlled) as Rayven's standard test tape. For accurate release testing with unique adhesives, we can apply and test the customers actual adhesive or test tape.
Rayven utilize the following Peel Testing Apparatus:
Color and Gloss Testing
In many coatings color and gloss are very important. This is especially true with inkjet coatings. Rayven test these characteristics with the following tools:
- BYK-Gardner, Micro-Tri-Gloss 20°60°85° gloss meter
- ColorTec-PCM- color, whiteness and brightness testing
Thick coatings such as adhesives and inkjet coatings are tested with TMI 49-70 digital measurement tools. Silicone release coatings are measured via X-Ray scanners from Spectro/ASOMA and Oxford Instruments. Rayven also has multiple Oxford Lab-X 3500 XRF analyzers for discrete sample testing. Coating thickness measurements are available for every roll produced by Rayven.
