Accelerated environmental (hygrothermal) exposure experiments are performed on organic paints coated on commercial die-cast AZ91D Mg alloys to investigate the effects of contamination on blistering. Specifically. artificial human perspiration spray is used to contaminate the substrate surface. Blistering occurred only for paints that are spread on surfaces with the perspiration present. https://balboasurfandsstylers.shop/product-category/kids-hat/
