The treatment of porosity is of particular importance in a variety of industries that include automotive, off-road, marine and industrial. In today’s market, customers require their products withstand ever increasing technical demands and stresses. With the increasing importance of quality assurance it is also becoming more difficult to find solutions for these challenges.
This is where IMP resins can help!
IMP impregnation sealants were developed to penetrate the porosity in castings and thereby give pressure tightness and durable sealing.
Improve Your Castings
IMP impregnation sealants are continually used where quality and durability is important.
- Transfer Cases
- Transmission Cases
- A/C Compressor Housings
- Engine Blocks
- Water Pump Crossovers
- Oil Pumps
- Fuel System Components
- Rack and Pinion Housings
- Axle Housings
- Torque Converter Housings
- Oil Pans
- Various Powdered Metal Parts
Typical materials that can be vacuum impregnated:
- Aluminum and magnesium alloys
- Grey iron castings
- Non-ferrous materials
- Sintered parts
- Brazed/welded assemblies
When impregnated with IMP sealant, components will be pressure tight and will maintain the physical and chemical properties of the original casting.
IMP sealants treat components against liquid and gaseous media.
Temperature stability is guaranteed within the working range -55 ºC to +200 ºC.
The IMP impregnation sealants are extremely resistant against acids, caustic solutions, solvents and gases.

Solve Surface Finish Problems
The impregnation technique and the special properties of the IMP sealants provide the best means of sealing pores in castings. It is an ideal treatment prior to plating and other surface finishes. If surface porosity is left untreated the surface can absorb plating fluids which may leak out and corrode the plated surface. After impregnation the surfaces of the components are free from residues and no additional cleaning is necessary.
The Manufacturer´s Expertise
Internationale Metall IMPrägnier GmbH was founded in 1986. Intensive research led to the development of the universally approved sealant IM3000. Continuing strong growth and increased product range led to further expansion in 1993 and 1995. Since 1997 the production has been largely automated. Continued growth saw a move in 2010 to even larger premises in Monheim encompassing state of the art computer controlled manufacturing.
The end-user can depend on competent advice from an active international specialist team.
