UV Coating
Since many dip molded products are made for outdoor applications, they are exposed to ultraviolet radiation on a regular basis. It is important, then, to choose coating plastic materials that fare well in UV light. Polyurethane and silicone perform the best in circumstances where they are exposed to ultraviolet radiation, and therefore, they are used as dip molded coatings. Although most dip molded products aren't habitually used in the outdoors or in sunlight, using UV resistant materials is still a good idea. Latex used to be a common plastic coating material of choice, but it performs poorly in UV light and is harmed and damaged easily if left in sunlight. It is now used only for products that require a high degree of elasticity.
Today, only products like disposable gloves and contraceptives are still dip molded out of latex. Every other plastic chosen exhibits a certain degree of UV resistance. The dip molding process using UV coatings is the same as using other less resistant plastics. The mandrel, or mold, is cleaned and dipped into the melted silicone or polyurethane coating. Depending on how thick the products walls will be, the mold is left in for a certain amount of time, no longer than a couple minutes, which is referred to as the dwell time. It is then removed at a slow and constant speed. The newly formed product is easily taken off the mold because every plastic coating material exhibits some degree of elasticity.
