The FIPG and CIPG Solution for Fast-Paced Production: Incure Uni-Seal 6322
On a high-volume line, a sealing material that needs minutes of oven time or a long moisture cure becomes the bottleneck. Incure Uni-Seal 6322 is a light-curable form-in-place and cure-in-place gasket material designed to seal electronic and automotive housings at the pace of automated production. The Case for Light-Cured Gaskets Traditional gasketing forces a choice between slow-curing liquid sealants and the inventory and fit problems of die-cut parts. A UV, visible, or LED light-curable FIPG or CIPG material removes that trade-off. The bead is dispensed exactly where it is needed, then cured on demand in seconds as the part passes a lamp, so throughput is set by line speed rather than by chemistry. What Uni-Seal 6322 Offers Acid-free formulation that will not corrode copper, solder, or fine-pitch conductors Low viscosity for precise dispensing into narrow channels and around tight corners Fast cure with low-energy LED lamps, suited to inline and conveyorized processes High resilience and memory retention, so the gasket recovers after compression cycles better than many cut elastomers Air-tight sealing against moisture, dust, and pressure differentials Moisture, temperature, and chemical resistance for under-hood and outdoor service Dual use as a temporary mask during conformal coating Building the Process Around It Bead and groove design. Give the dispensed bead a defined cross-section and a target compression of roughly 20 to 40 percent when the housing closes. Consistent geometry is what makes the seal repeatable unit to unit. Dispensing. A positive-displacement dispense head keeps bead volume constant as the material warms or the reservoir drains. Programmed paths hold the bead centered on the flange through corners and changes in direction. Curing. Size the lamp to the largest part so the entire bead reaches full cure in one pass. For long or complex flange paths, an inline conveyor curing system or a correctly matched UV LED flood lamp keeps cure time in step with takt. A cured gasket and a metal or plastic housing expand at different rates, so a seal that is fine at room temperature can loosen in the cold or over-compress when hot. Weighing how thermal expansion mismatch stresses a sealed joint guides the choice between a firmer and a more compliant grade.

Production Benefits Switching to a light-cured poured gasket typically shortens cycle time, cuts gasket inventory and scrap, reduces rework by forming the seal in one controlled step, and gives engineering the freedom to revise flange geometry without new tooling. The same material can seal a control-unit housing on one line and mask a board for coating on another. Resilience and Compression Set A gasket's job is to keep sealing after it has been compressed, warmed, cooled, and vibrated for years. The property that describes this is compression set: how much permanent deformation remains after the load is removed. A material with high compression set gradually loses its sealing force and the joint starts to leak,…
