The Elcometer 139 Amine Blush Chip Screen Test Kit (E139-C) is a rapid colorimetric test for the quick identification of amine blush (carbamates) on the surface of coatings, using small chips or shavings of the coating. Amine blush can develop on amine-cured epoxy coatings and, if present when the film is re-coated, leads to inter-coat adhesion failures, so detecting it before applying the next layer prevents costly adhesion problems in a multi-coat system.

The test works by a visual colour change: the presence of amine blush is indicated by a change in colour of the test solution when compared against a control sample. The result is a straightforward determination of whether amine blush is or is not present on the coating's surface, rather than a measured quantity. Because it works on chips or shavings, the Elcometer 139 Amine Blush Chip Screen Test Kit suits samples taken from the coated surface for screening.

The Elcometer 139 Amine Blush Chip Screen Test Kit measures 172 by 110 by 100mm and weighs 310g, and is supplied with the buffer solution sampler tubes, diluent solutions, test reagents and pipettes needed to run the test. Used by coatings inspectors and applicators working with amine-cured epoxy systems in corrosion protection, marine and industrial coatings, the Elcometer 139 Amine Blush Chip Screen Test Kit is supplied by BAMR, South Africa's authorised Elcometer distributor.
