Block resistance is the ability of a coating to resist sticking to another surface and to resist any change in appearance when it is pressed against that surface. BS EN 927‑10 discusses the block resistance of paints and varnishes on wood.
BS EN 927‑10 specifies a test method for determining, under specified optional conditions, whether a single-coat film or a multi-coat system of paints and varnishes on wood after a specified drying period is sufficiently dry to avoid damage when two painted surfaces or one painted surface and another surface are placed in contact under pressure and subsequently separated
BS EN 927‑10 on block resistance on wood is useful for:
As a manufacturer of coatings such as paints and varnishes, you would like to test your products for various purposes. Testing helps you to understand which products are best suited for certain substrates. It also helps you to determine how to evolve newer products.
BS EN 927‑10 provides you with the parameters for sample preparation. BS EN 927‑10 gives you details about the preparation of strips and specimens, conditions of the test, climatic conditions for the test, evaluation, and test report. BS EN 927‑10 helps you to determine the level of block resistance on wood for the product being tested.
