Why Uni-form Epoxy Preforms?

Liquid epoxy is messy, inconsistent, and time-consuming. Uni-form epoxy preforms are clean, consistent, and quickly dispensed. Uniform results make Uni-forms the no-mix, no-mess solution to liquid epoxy problems.

Multi-Seals' one-part epoxy resins are solid at room temperature. When heated, they melt and cure, forming a consistent seal that protects components from dust, moisture, oil, flux, industrial cleaning solvents, conformal coatings, and other contaminants. Fully cured MSI epoxy will not reflow when exposed to subsequent elevated temperatures.

Liquid Problems		Solid Solution
Drips Liquid epoxy drips from syringes onto contacts or other unwanted areas of a component.		No Drips Uni-forms are pre-shaped and remain solid until they are heated, so epoxy flows only onto desired component features.
Mix Variations Mixing and metering variations cause variations in liquid epoxy performance.		No Mix Required Multi-Seals predetermines the ratio of catalyst to resin to produce a complete one-component system. Results are predictable and consistent.
Pot Life When liquid epoxy is not dispensed within pot-life parameters, dispensing equipment can become clogged. Any mixed and unused two-part epoxy must be discarded.		No Pot Life Uni-forms have no pot life concerns. Unused material is simply saved until it is required for the next production run.
Viscosity Creep Liquid epoxy continues to polymerize as it is dispensed, causing equipment clogs and variations in viscosity and seal quality.		Viscosity Consistency The viscosity of Uni-forms remains consistent from seal to seal, batch to batch. The millionth seal will look the same as the first seal.
Poor Inventory Control Liquid epoxy creates poor inventory control. Operators have difficulty estimating the exact amount of liquid epoxy required to seal a given batch of components. A large percentage of epoxy is wasted by misdispensing, improper mixing, clogged needles, or operator error.		Simple Inventory Control Uni-forms simplify inventory control. Determining the number of preforms required for a given batch is as simple as determining the number of required seals.
Slow Manual Dispensing Manually dispensing liquid epoxy is time and labor intensive.		Rapid Manual Dispensing Uni-forms can be manually dispensed at rates that far exceed manually dispensed liquids.
Expensive Automated Dispensing Automated dispensing systems for liquid epoxy are often expensive and require extensive operator instruction. Most equipment is prone to clogging and pot life concerns. Constant adjustments for epoxy viscosity variations, clogs, and air entrapment require highly skilled labor to run and maintain dispensing equipment.		Affordable Automated Dispensing Uni-forms are well suited for a variety of automatic or semi-automatic equipment. Templates, Pick & Place, and Bowl Fed Gravity Tracks such as the Uni-matic Loader are all practical methods for loading Uni-forms. Automated loading rates can range from 200 to 600 ppm, depending on loader, component, and preforms design.
Difficult Pre-Cure Removal Once liquid epoxy is dispensed, it cannot be easily removed from unwanted areas. As it starts to cure, reworking becomes increasingly difficult.		Simple Pre-Cure Removal Uncured Uni-forms are easily removed from components, allowing for greater flexibility and reducing the number of scrapped parts.
Messy Cleanup Liquid epoxy usually requires extensive cleanup procedures, including the use of toxic solvents and the disposal of epoxy waste.		Simple Cleanup Uni-form epoxy preforms require minimal cleanup procedures. Preform residue is easily swept up. Handling equipment need only be wiped down once or twice a week.
Costly Expensive dispensing equipment, time-consuming procedures, skilled labor, wasted epoxy, scrapped components, and product returns from seal failures add high expenses to liquid epoxy dispensing.		Cost-Effective Affordable loaders, inventory efficiency, reduced labor, minimal or no scrap, and product return prevention minimize the hidden costs often associated with epoxy sealing.
Variable Quality Liquid epoxy seals vary in shape, size, and location, causing variations in seal performance and quality. Epoxy drips on critical component areas jeopardize product performance.		Precision Quality Tight dimensional tolerances and viscosity consistency ensure repeatable, high-quality seals. Precise, consistent results contribute to product quality.
