The British Coatings Federation (BCF) announced plans to tackle the issue of leftover decorative paint, much of which ends up in landfills. The plan includes implementing PaintCare, an industry-led project to help create a circular economy, aiming to make better use of the estimated 50 million liters of leftover decorative paint generated each year in the country.
Solveing The issue of leftover decorative paint not only need to make better use of Coating ,but also make sure of the use ages .such as the scratch resistance.Scratch resistance is not uniquely defined, and is difficult to measure. Different terminologies are used, ranging from marring for optical defects towards friction, wear, erosion, abrasion and cracking for mechanical defects.1,2 The scratch resistance can be evaluated in terms of gloss reduction, haze, magnitude of deformation, resistance towards deformation, weight loss or color change of the substrate.Coated surfaces need to be tested for resistance to abrasion caused by a brush, sponge, or other means.
The Wet Abrasion Tester or scrub Abrasion tester produces a repeatable, controlled condition to simulate everyday use or wear patterns.The abrasion tester can examine washability and related properties that affect the stain resistance of coatings. Detergent performance testing can also be determined in a reproducible manner.
This machine is widely used to test the resistance of many materials to scrub, abrasion and washing. Paints, varnishes, other coatings and finishing can be applied on various supporting media e.g. plastic, glass, wood, paper, leather and submitted to the accelerated test, by reciprocating brushes, sponges or abrasives on the samples with (or without) reagent depending on methods. When applicable, the machine is fitted with a dosing peristaltic pump.
