GB/T 23982-2009 "Test Method for Blocking Resistance of Wood Coatings" specifies the method for determining the blocking resistance of wood coating films, applicable to various types of wood coating products. The test involves placing two coated film samples in contact, applying a specified pressure, and maintaining them at a specific temperature for a set duration. The blocking resistance is evaluated based on the force required to separate the samples or the extent of damage observed on the film. The test requires instruments such as a blocking resistance tester, weights, a constant temperature chamber, and a tension meter, providing a basis for assessing the application performance of wood coatings.
