Chemical resistance test

Analysis of the chemical resistance of a coating or material.

Can be applied to:

Coatings

Test method standards:

ASTM D1308, ISO 2812, ASTM D4752

Test procedures:

1. Chemical resistance “spot” test
A small volume of the test liquid is brought into contact with the material surface and is covered with a cover glass. After a certain period of time, the influence of the liquid on the test surface is examined. Usually the contact time is limited to minutes, several hours or 1 day.

2. Solvent resistance rub test (MEK)
The solvent rub test is used for checking the degree of cure of a baked film by rubbing the surface with a cloth soaked with MEK. The amount of rubs until failure are counted.

Lead time:

Approximately 5 business days.

All tests – composites – metals – plastics – coatings – adhesives – 3D prints
