Avex Air


Avex Corrosion and Tools operates from its two distribution centres in Cape Town and in Swakopmund, and is the latest addition to the Avex Group of companies. It is an accredited distributor for, and proudly associated with Lear Chemical Research, an internationally recognised developer of compounding anti-corrosion lubricants and greases, including market-leading products Corrosion Block and ACF-50.

Lear Chemical Research has, for over thirty years, been developing products that specifically address resolving corrosion-related problems that occur in the automotive, aviation, industrial, marine and recreational industries. Its technical success is achieved by combining laboratory testing with specific field evaluations to ensure that each formula produced delivers both on advertised claims and customer expectations. More information on the company can be found at www.learchem.com

Preventative corrosion maintenance is a key factor in the management of equipment downtime, and Avex Corrosion & Tools Solutions supplies a broad range of industries, including private customers and resellers, with these industry-leading products.

The company’s main distribution centre in Cape Town undertakes the majority of the distribution across the African continent, with the Swakopmund-based distribution centre looking after the Namibian market. 


This state-of-the-art anti-corrosion formula was specifically developed for the aerospace industry and  is most commonly used on aeroplanes, however is also a popular lubricant for motorcycle enthusiasts.

Presented as an ultra Thin Fluid Film Compound (TFFC) that actively treats metal by using advanced polar bonding technology. ACF-50’s synthetic inhibitors and active chemistry penetrate through the oxide deposits (white powder) to the base of the corrosion cell. Here it emulsifies, encapsulates, and then lifts the electrolyte away from the metal surface, stopping the corrosive process. It then allows this moisture to evaporate while providing an atmospheric barrier that prevents further moisture contact. 

ACF-50 actively penetrates the tightest seams, lap joints, micro-cracks, and rivet heads, displacing moisture and other corrosive fluids in these corrosion-prone areas. Its thin film remains active for up to 24 months.

The product is easy and inexpensive to apply and significantly reduces corrosion in structural and electrical systems. Other product highlights include:

  • Prevents and deactivates corrosion
  • Protects airframe and components
  • Non-toxic and low VOC
  • Protects against all common electrolytes
  • Does not interfere with NDT procedures 
  • Is easy to apply (aerosol / fogging)
  • Equipment includes seven application wands

Corrosion Block® 

This unique product has the ability to prevent and stop corrosion in a broad spectrum of metal and electronic equipment. It is a product of choice in a number of industries, including the marine, mining, industrial, agricultural aand leisure sectors. 

In addition to being used for the maintenance of sporting equipment including trailers, motorbikes, quad bikes, snow-bikes, jet-skis Corrosion Block® it has also grown increasingly popular for golf course maintenance, from the golf cart fleet through to the turf and grounds equipment.

Corrosion Block® is presented as a clean, clear, ultra-thin fluid that protects both metal and electronic equipment, both during use, or when it is stored away. The fluid creates a hydrophobic, non-greasy atmospheric film or barrier that protects all metal surfaces and chemically neutralises salt water.

It can be sprayed, brushed or wiped onto surfaces, and as it does not contain wax, resin, tar, asphalt, silicone or Teflon it does not leave a gummy residue behind. 

The product is available as an aerosol or in a tub (grease), and outperforms competitive grease by a ratio of 5:1. Other product highlights include:

  • Safe for the work place and environmentally friendly
  • Offers excellent thermal / oxidative stability
  • Offers excellent extreme pressure (EP) properties
  • Suitable for sealed-for-life applications
  • Dielectric / non-conductive
  • Resits bleeding / melting at high temperatures
  • Is multi-grease compatible
  • Corrosion Block Grease

Corrosion Block Grease is a high-performance, multi-purpose grease. It is a highly-effective, salt water resistant grease that contains a unique non-clay-based thickening system. This powerful lubricant is compatible with most other greases, thereby simplifying change overs.

Corrosion Block Grease outperforms lithium and most synthetic greases, and has exceeded the requirements for NLGI Service Classification GC-LB (for automotive wheel bearing and chassis lubricants), which is based on ASTM D4950 performance requirements.

Corrosion Block Grease keeps its original consistency and viscosity; won’t wash out, separate or cake; and remains active against corrosion for up to 12 months. It is suitable for use on high-speed bearings, as well as sealed-for-life bearings and is non-toxic, non-hazardous, non-flammable and non-conductive.

The combination of these unique features makes Corrosion Block Grease a popular, highly versatile, and trusted grease used by many satisfied clients from commercial and public sectors around the world.

Corrosion Block Grease features include:

  • Excellent, extreme pressure (EP) properties
  • Excellent thermal stability
  • Outstanding oxidation stability
  • Non-conductive and non-dielectric
  • Heavy metal free
  • Free of environmentally objectionable materials
  • Superior corrosion protection
  • Resistant to saltwater
  • Outstanding low temperature mobility
  • Compatible with most grease types
  • Is distinctive aqua blue in colour

Further Corrosion Block Grease benefits include:

  • Protection of heavily loaded equipment and extension of bearing life
  • Resistance to running, bleeding and softening at high temperatures
  • Suited for extended periods of operation at elevated temperatures and sealed-for-life applications
  • Suitable for use in electrical applications that require grease
  • Environmentally-friendly and workplace-safe
  • Does not soften, breakdown or wash out in wet applications,
  • Suitable for use in centralised lubrication systems and low temperature environments
  • No cross contamination concerns when converting
  • Easy identification and high visibility
