Introduction
Product Introduction & Applications
The Putty Sanding Tester is designed to evaluate the abrasion resistance and sanding performance of putty coatings. It simulates the sanding process by applying a controlled load and reciprocating motion to the test sample. This instrument is widely used in paint and coatings production, construction materials, quality control laboratories, and research institutions to ensure the consistency and durability of putty surfaces.

Clean the sanding head and test template after each test to maintain accuracy.
Operate the instrument in a dry, stable environment to prevent measurement errors.
FAQ
What materials can be tested with this instrument?
It is suitable for putty coatings used in paints, construction materials, and related applications.
How is the sanding load adjusted?
The load is adjustable by the weight of the grinding head and additional counterweight blocks.
Can the friction speed be changed?
Yes, the speed is adjustable from 0 to 190 times per minute.
What is the test stroke of the instrument?
The standard stroke is 155 mm, which represents the movement distance of the grinding head on the sample.
How do I maintain the tester for long-term use?
Clean the grinding head, counterweights, and test templates after use; store in a stable, dry environment to ensure consistent performance.
