Putty Sandability Tester
The Putty Sandability Tester is designed according to GB/T 1770-2008 “Test Method for Sandability of Coatings and Putty Films”. It is used to evaluate the sandability of primers and putty by reciprocating the test specimen under controlled load. The instrument measures wear after a specified number of sanding cycles, providing objective assessment of primer or putty resistance to sanding. The system features microcontroller-based intelligent control, stepless speed adjustment, and automatic cycle counting with real-time display.
Application
(1) Evaluation of sandability for primers and putty in automotive, furniture, or industrial coatings
(2) Quality control for coating and putty performance
(3) R&D assessment for new primer or putty formulations
(4) Laboratory testing of coating systems before production scale-up
Standards
(1) GB/T 1770-2008 Test Method for Sandability of Coatings and Putty Films
(2) ASTM D 2187 (optional, comparable method for coating sandability)
(3) ISO 15184 (for comparative sandability tests of paint films)

Test Procedures
Mount the test specimen on the sanding platform.
Install the sanding head and select the appropriate additional weight.
Set the desired friction speed and number of cycles on the LCD controller.
Start the test; the instrument will perform reciprocating sanding automatically.
Observe and record wear on the test specimen.
Retrieve cycle count and assess sandability based on wear and load applied.
Maintenance Information
(1) Clean the sanding head and test table after each use to prevent residue accumulation.
(2) Inspect and tighten weights and fasteners regularly.
(3) Verify counter and speed accuracy periodically.
(4) Avoid moisture exposure to electronic components.
(5) Lubricate moving parts as required for smooth operation.
