Polymeric has developed a brilliant one-part silver for scratch-off applications. When used in combination with the 20489 SP Release Clear, the Silver easily scratches off, leaving no staining. The Silver has shown to work well over certain soy-based and water-based primer coats as well as the 20489. A pretest should be done prior to any production using soy or water-based primer coats. The Polymeric Technical Service team offers pretesting of the Silver with any customer supplied primer coats.
