Industry-approved sealing solutions

Thanks to our unmatched portfolio of sealing resins and a fully automated high-speed vacuum impregnation system, we can offer outstanding sealing solutions for your powertrain electronics, connectors, power supplies, heating and air-conditioning systems, AEV power generation systems, tire pressure monitoring systems, safety and driver assistance systems, and fuel delivery systems.

Vacuum impregnation equipment includes dry and wet vacuums used to prepare the resin. The absence of liquid within the dry vacuum method ensures no interference with degassing the pores. Within the wet vacuum method, penetration of the resin into the part takes place at atmospheric pressure, enabling rapid processing. Once prepared, the resin fills porosities, shrinkage cavities, capillary pores and cracks to ensure resistance to external influences.

Excess sealant is removed from part surfaces through a drip-off and spin process; the most effective method for removing excess sealant with no risk of damage to the parts, while requiring very little time.

Parts are washed, using the oscillator for agitation, and the centrifuge prepares for the rinsing step. Compressed air agitation in the water also may be used.

Parts are rinsed and the centrifuge prepares for the curing step. When exposed to the activator rinse, sealant at the pore entrances will cure quickly, creating a “plug” that prevents remaining liquid sealant from escaping while it continues to cure slowly by the anaerobic system.

Parts are soaked within a final rinse tank of water at 50 degrees Celcius, removing the activator solution, and quickly drying and curing the part.
