Our range of sealants and surface coatings primarily seal the low-level porosity (as little as 0.1%), that can compromise the corrosion performance of even the best coatings. Each sealant can have additional characteristics such as being non-wetting to molten metals, improving wetting, reducing friction or improving fiber release. Additionally, some of our proprietary sealers offer exceptional acidic corrosion resistance for some of the worst corrosive environments as well as exceptional electrical resistance properties for applications requiring insulation. By combining the optimum sealant and coating to suit the application, we improve life, wear, corrosion resistance and overall performance to levels not possible with unsealed surfaces.
Let our highly skilled staff find the correct sealant for your application.
We are constantly expanding and updating our range of coatings and sealing systems to adapt to ongoing market developments.
The Gartseal 622 coating produced in this way is <5µm thick with a hardness up to 2,900 VPN. In addition to the significant increase in surface hardness, corrosion resistance and frictional properties are improved.
The same techniques can be used to seal the surface of other porous materials such as solid ceramics and sintered metals. If the impregnation is vacuum-assisted, full penetration of the porous structure can be achieved and filled to produce a harder and stronger component.
Flame-sprayed coatings and electroplated hard chrome can also benefit from the Gartseal 622 densification process. These coatings are by nature micro-cracked and porous and therefore susceptible to interface corrosion problems. The penetration performance of the Gartseal is so efficient that the micro-cracks in hard chrome can be filled to improve both wear resistance and corrosion performance.

In addition to the sealants above, we are happy to develop custom seal materials for the most demanding thermal spray or plated surfaces.
