Overview
The film drying time tester TR 3605 is a professional instrument of the TRUIT brand for determining the drying time of coatings or paints. It is widely used in the painting industry and Coatings R & D laboratories to evaluate the drying performance of coatings and determine the appropriate operating time. The instrument is made of stainless steel, has a bottom area of 1cm ², a self-weight of 200g, and is designed in accordance with GB/T 1728 standards. It is suitable for the determination of film and putty film drying time, where the surface film formation time is defined as the surface drying time.
Features
1. Made of stainless steel, it is durable and easy to clean.
2. With a bottom area of 1cm ², the design is accurate and easy to operate.
3. Weight 200g, meeting standard requirements to ensure test accuracy.
4. In line with GB/T 1728 standard, it is suitable for the determination of drying time of film and putty film.
Principle
The tester measures surface drying time by observing the time of surface film formation by applying pressure to the surface of a film or putty film using an instrument weighing 200g under specified drying conditions. Its design is based on standard methods to ensure Reliability and conformity of test results.
Applications
Painting industry, Coatings R & D laboratory
Steps
1. Prepare the film or putty film sample to be tested.
2. Place the tester on the surface of the sample to ensure that the bottom area is in full contact.
3. Under the specified drying conditions, observe the surface film formation.
4. Record the time from start to surface film formation as surface drying time.
Notice
• Make sure the tester is clean before use to avoid contaminating the sample.
• The operation should be carried out under the specified drying conditions to ensure the accuracy of the test.
• Regularly check the status of the instrument and maintain it in time if it is damaged.
• Follow relevant safety regulations and avoid use in flammable environments.
