QGS Paint Film Drying Time Tester, Paint Film Drying Time Testing Instrument, Paint Film Drying Time Measuring Device, Coating and Putty Film Drying Time Measurement

Overview of the Paint Film Drying Time Tester

Designed and manufactured in accordance with GB/T 1728-89. Under specified drying conditions, the time required for the surface film to dry to a touch-dry state is defined as the surface-drying time. The time required for the entire coating film to fully cure into a solid film is defined as the actual drying time, expressed in hours. This method is applicable to the determination of the actual drying time of coating films and putty films.

Paint Film Drying Time Tester Equipment and Instruments

1. The total weight of the weights is 200 ± 0.2 g, with a base area of 1 square centimeter.

2. Stopwatch, degreasing cotton, filter paper, and tweezers (to be provided by the participant)

3. The test must be conducted at a temperature of 23±2°C and a relative humidity of 50±5%.

The paint film drying time tester is used to determine the actual drying time of the paint film.

The physicochemical process by which a paint sample applied to an appropriate surface transitions from a fluid layer to a paint film is referred to as drying.

The drying process is divided into two main stages:

When a thin film of paint forms on the surface of the coated sample, it is referred to as surface drying.

When the entire thickness of the applied paint has formed a continuous film, it is referred to as true drying.

1. Equipment and Utensils

a. Drying Time Tester

Includes one weight with a total mass of 200 ± 0.2 grams and a base area of 1 square centimeter.

One pack of cotton wool

One pair of tweezers

b. Stopwatch

c. Glass plate (9 × 12 cm), or tin-plated and slag-free mild steel sheet (9 × 12 cm), or lead sheet (5 × 14 cm)

d. Room-temperature drying oven

Note: Items 2, 3, and 4 must be provided by the customer.

2. Operating and Usage Steps:

a. Pre-test preparations:

Adjust the weight of the砝码 to meet the requirements:

Make the cotton wool into a loose cotton ball with a volume of 1 cubic centimeter.

Prepare test panels in accordance with the technical requirements specified in the product standard and complete the surface-drying measurement; then place the panels in a drying oven for drying as prescribed in the operating procedures.

b. According to the actual drying time specified in the product standard, remove samples at regular intervals during the drying process and test their degree of dryness.

During the test, place a cotton ball on the surface of the paint film, gently set the paint-drying test weight on top of the cotton ball, and simultaneously start the stopwatch. After 30 seconds, remove the weight and the cotton ball; if no trace of the cotton ball remains on the paint film, the coating has reached the stage of true dryness.
