16、(E) BSI 2011 1IntroductionCoating powders are subject to two distinct ageing mechanisms: one involving the physical state of the powder and the other its chemical reactivity. Changes in the coating powder may lead to deterioration in the physical and chemical properties of the final coating.This par
17、t of ISO8130 describes the procedures to be adopted in assessing the tendency of a thermosetting coating powder to maintain its physical and chemical integrity after being subjected to defined storage conditions.1 ScopeThis part of ISO8130 deals with the estimation of the storage stability of thermo
18、setting coating powders. It specifies the procedures for determining the changes both in the physical state of a thermosetting coating powder and in the chemical reactivity of the powder, together with its capacity to form a satisfactory final coating. A correlation between changes in different prop
19、erties is not to be expected. Similarly, there may be no correlation between the results obtained under different storage conditions.The results of the procedures specified in this part of ISO8130 give an indication of the ability of the coating powder to withstand the effects of storage prior to ap

At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on th
