Adhesive preforms ensure that seals in design match seals in production by eliminating the drips, inconsistencies, and waste typical of liquid dispensing. While pre-shaping the sealant eliminates variations associated with operator technique and manufacturing location, determining the right adhesive for an application is as important as determining the preform geometry. Material viscosity, chemical and heat resistance, and flexibility all influence seal repeatability and performance. This paper from MULTI-SEALS discusses the adhesive options available to match a component's design and operating environment.
