Solvent Resistance (Double Rub) Test

Purpose of Test:

To evaluate the solvent rub resistance of an organic coated steel sheet that chemically changes during the curing process.

A greater solvent resistance indicates that the paint film is more stable and durable for outdoor exposure.

A mechanical rubbing machine provides consistent stroke length, rate, pressure, and contact area. The test is performed using the organic solvent methyl ethyl ketone.

Device/Machine: A Mechanical Rubbing Machine.

Approximate  Test Duration:

o  Sample preparation and Test time: 30 minutes

Specification: ASTM D7835
