SF283
This paint film drying time tester (also known as coating drying time tester or drying tester) uses the weight method principle, specifically designed for determining the actual drying time of coatings and putty films. Observing marks left by a cotton ball or filter paper on the coating to judge the actual drying degree. It is essential equipment for coating production and quality control processes.
Test Principle: Under specified temperature (23±2℃) and humidity (50±5%RH) conditions, place the tester on the coating surface. After a 30-second load period, remove it and gently wipe with a cotton ball or filter paper, observing whether marks remain on the coating surface to determine the actual drying degree.
Technical Parameters:
Total Weight: 200±0.2g, ensuring constant test load
Base Area: 1cm², base diameter 11.3mm, uniform pressure distribution
Test Duration: 30 seconds, standard test time
Environmental Requirements: Temperature 23±2℃, humidity 50±5%RH
