Coating powders - Part 11: Inclined-plane flow test (ISO 8130-11:1997)

Publication date:   Jan 21, 2011

Scope

Specifies a method for determining the flow characteristics of a fused thermosetting coating powder down a plane inclined at a set angle to the horizontal. the result of the test described gives an indication of the degree of melt flow that may occur during the curing of the coating powder. This characteristic contributes to the coherence of the coating, to its surface appearance and to the degree of coverage over sharp edges. The test acts as a useful method for checking for batch to batch variation in the behaviour of a given coating powder. Correlation between the results from coating powders of differing composition is not to be expected. This method is unlikely to yield meaningful results with coating powders which have gel times of less than one minute at the test temperature when characterised according to ISO 8130-6.
