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.
It measures the number of scrub cycles a coating can withstand before showing wear, damage, or substrate exposure.
This machine helps evaluate coating durability and washability, ensuring surfaces can withstand real-world cleaning conditions.
Evaluating scrub resistance of coatings
Testing paint durability under cleaning conditions
Comparing coating formulations
Supporting laboratory quality control
Conducting coating research studies
One-line answer:
It repeatedly scrubs a coated surface under wet conditions to measure coating durability.
Coated panel is mounted on the test platform
Brush or pad is positioned on the surface
Liquid medium is applied
Brush moves in reciprocating motion
Test runs for programmed cycles
Surface is evaluated for wear or failure
Scrub resistance is the ability of a coating to withstand repeated cleaning without losing its protective or visual properties.

What does NWASM-100 measure?
It measures the scrub resistance of coatings by counting the number of cycles before failure.
What materials can be tested?
Paints, coatings, and surface finishes are commonly tested.
How is scrub resistance determined?
By measuring how many scrubbing cycles a coating withstands before damage occurs.
Why is liquid used?
To simulate real cleaning conditions.
Which standards are followed?
ASTM D2486, ASTM D3450, and ISO 11998.
When should this machine be used?
When evaluating coating durability under cleaning conditions.
Wet Abrasion Scrub Machine NWASM-100 is designed to evaluate the scrub resistance and wash durability of paints and coatings under controlled wet cleaning conditions. It uses reciprocating brush motion, liquid application, and programmable scrub cycles to measure coating wear and failure. Widely used in coating, construction, research, and quality control laboratories, the system supports ASTM and ISO standards for paint durability and surface performance testing.
