Solid alternative to liquid epoxy sealing
Multi-Seals offers a solid alternative to liquid epoxy for high-volume, precision sealing. Uni-form epoxy preforms are pre-shaped, one-part resins that are solid at room temperature. When heated, Uni-forms melt and cure, forming a consistent seal that protects components from dust, moisture, oil, flux, solvents, conformal coatings, and other contaminants.
Close tolerances on preform dimensions, consistent pre-mixed ratios of resin to catalyst, and consistent viscosity from beginning to end of batch ensure uniform, high-quality results. Uni-forms eliminate seal variations caused by operator technique or epoxy pot life. Costly cleanup procedures are also avoided.
To accommodate diverse applications, Uni-forms are available in several epoxy formulations and a wide range of configurations, with inside diameters as small as 0.25mm and outside diameters as large as 18.3 mm. Preforms can be dispensed as rapidly as 200 to 600 parts per minute with little or no operator training. Typical preform configurations range from US$0.025 to US$0.005 each, depending on preform size and order quantities.
