What is BS EN 927-11 about?
BS EN 927 discusses paints and varnishes. BS EN 927-11 specifies a laboratory test method for assessing microfoam in coating films on wood components. Samples are taken from finished wood components that are produced in a production plant, by craftsmen or a laboratory.
The test method in BS EN 927-11 can be used for further evaluation together with the performance specification given in EN 9272. The amount and size of microfoam depend on the coating material, the substrate, and the application process as well as conditions.
Who is BS EN 927-11 for?
BS EN 927-11 on paints and varnishes is useful for:
- Paint Manufacturers
- Testing Laboratories
- Manufacturers of wooden furniture
Why should you use BS EN 927-11?
Film coating involves adding a thin layer film-foaming polymeric onto a product substrate. Foaming can occur during this process. Several defoaming mechanisms readily dissipate macrofoam, but microfoam is different and a complex issue that requires addressing. Owing to its small bubble size, microfoam is generally not visible to the naked eye but its negative effects on a dried coating cannot be missed: surface defects, colour control and clarity/haze. BS EN 927-11 provides a test method to assess microfoam in coating films on wood components. BS EN 927-11 provides you with a test procedure to conduct the test.
