ASTM D7835/D7835M Solvent Resistance of an Organic Coating using a Mechanical Rubbing Machine

ASTM D7835/D7835M explains a mechanical rub method for evaluating the solvent resistance of an organic coating that chan ges during the curing process. This process is carried out in a mechanical rubbing machine. It is typically used in laboratories or in fabric shops. SI units or inch-pound units are considered standard units.... Read More

Scope:

ASTM D7835/D7835M is quite reliable for measuring solvent resistance by using a mechanical rubbing machine. The mechanical rubbing machine provides consistent stroke length, rate, pressure, and contact area that are not subject to variables such as human fatigue. The test solvent used in the rubbing machine has a significant effect on the number of double rubs measured.

Procedure:

The ASTM D7835/D7835M test is carried out by an automated machine. It determines the solvent resistance of a coating by rubbing a cloth saturated with the solvent across the coating and counting the number of strokes (double rubs) it takes for the coating to break-through or fail.

Video 01: ASTM D7835 Determination of solvent resistance of an organic coating

Specimen details:

The double rub (stroke) length must be 20 ± 2 cm [8 ± 0.8 in.] for ASTM D7835/D7835M testing.

Result:

The solvent resistance of an organic coating is calculated by using a mechanical rubbing machine.

Conclusion:

ASTM D7835/D7835M explains a mechanical rub method for evaluating the solvent resistance of an organic coating that changes during the curing process.
