Process
From materials for which there are no test plates or films for permeation measurement, Mecadi makes the test samples itself.
Examples: adhesives, castables.
Possibilities at Mecadi:
Sample preparation of thermally or UV-curing systems
(No die casting)
What do we need?
- Approx. 20 ml (In case of 100 % solids) per pattern (Or after prior consultation)
- Data sheet of handling
- Safety Data Sheets
What do we do?
- Selection of substrate depending on the desired permeation test (preferably permeable)
- Selection of substrate chemically compatible, non-absorbent
- Pretest coatability (wettability, film formation)
- Preparation of test samples
- Thermal curing (up to 300°C), for example, chemically crosslinking or steam systems or UV-curing
- Also handling of 1K systems including cold storage (-18°C) possible
- 1K/2K-Systeme processible, also more complex mixtures
- Pretreatment: mixing, outgassing, filtering possible
- Layer thickness: according to requirements, typically > 10µm up to several millimeters
- On carrier or carrier-free
- Lab coat: Coating knife, spiral coating knife, screen process, dip coating, spray, etc.
- Optical: Thin layers < 10 µm under clean room / glovebox conditions
- Characterization
- Inspection for defects (dye test , optical, leakage testing using gas or liquids)
- Blanks
- Masking
-> Use in permeation test
Costs:
Please ask for offer / project-specific according to expenditures
Materials:
- Coatings (e.g. corrosion protection coatings)
- On carrier film (e.g. packaging films, elastomers, fluoropolymers, polymeric films such as PVC, PET, polyolefins, PE-metallocenes, copolymers)
- On porous carriers (membranes)
- On inspection sheets
- Adhesives (e.g. epoxides)
- Coatings (e.g. nano- coatings)
- Silicones (e.g. 1K silicones, 2K silicones)
- Casting compound
