REWITEC™ surface repair additives
REWITEC is a Croda subsidiary that specialises in improving the longevity and energy efficiency of systems, machinery and gearboxes with a range of nano- and micro-particle based surface repair lubricant additives. Simply put, our products improve the service life of lubricated moving machinery.
Moving machinery continuously poses a challenge to engineers everywhere: How to improve durability, longevity and reduce frictional losses. These losses can significantly increase costs associated with down time, repair and replacement of components.

What can REWITEC technology do?
REWITEC technology is not limited to any one application or area; instead, the technology can benefit any lubricated moving metal system. Independent, third party tests demonstrate a significant reduction in surface roughness, friction and temperature where the technology is deployed and offers:
- A reduction in abrasion and wear
- Reconditioning of metal surfaces exposed to friction
- Vibration reduction
- Permanent wear protection
- Significant optimisation of the original material properties
- Improved film formation
- Reduced spare parts requirements and reduction in replacement component costs
- An extended service life.
How does REWITEC work?
The existing lubricant is used as a carrier to deliver REWITEC technology to the mixed friction areas with the lubricated component
The REWITEC particles react to the increased temperatures produced in the mixed friction zones, causing them to physically bond to the areas with high friction
The surfaces exposed to friction are given a ceramic quality and a new corrosion-resistant metal-ceramic surface is created. Friction and wear at the treated surfaces is significantly reduced while the lubricant properties remain unchanged.
How is REWITEC supplied?
For our oil additives (DuraGear™ and PowerShot™) the concentrated active agents are generally supplied pre-mixed in a neutral white oil, which is compatible with practically all standard lubricants. Products compatible with other oils, such as polyalkylene glycols (PAGs) can also be supplied.
We have the capability to directly apply our products to your own lubricants, supplied to us. Just contact us and we will be happy to advise you.
For greases (GR 400) we can either receive your grease, add the REWITEC additive and then supply the mixed grease back to you or we can supply you with the grease additive for you to mix into your own grease.
