Wet Abrasion Scrub Machine NWASM-100 – Coating Scrub Resistance Testing Equipment

What Is Wet Abrasion Scrub Machine NWASM-100?

Wet Abrasion Scrub Machine NWASM-100 is a laboratory instrument used to measure the scrub resistance of coatings and paints by simulating repeated cleaning using brushes under controlled wet conditions.

What Does This Machine Measure?

It measures the number of scrub cycles a coating can withstand before showing wear, damage, or substrate exposure.

Why Is This Machine Important?

This machine helps evaluate coating durability and washability, ensuring surfaces can withstand real-world cleaning conditions.

Product Snapshot

What Is This Product Used For?

• Evaluating scrub resistance of coatings

How Does Wet Abrasion Scrub Machine NWASM-100 Work?

One-line answer:
It repeatedly scrubs a coated surface under wet conditions to measure coating durability.

Step-by-Step Working Process:

1. Coated panel is mounted on the test platform

2. Brush or pad is positioned on the surface

3. Liquid medium is applied

4. Brush moves in reciprocating motion

5. Test runs for programmed cycles

6. Surface is evaluated for wear or failure

What Is Scrub Resistance?

Scrub resistance is the ability of a coating to withstand repeated cleaning without losing its protective or visual properties.
