Excessive corrosion and the subsequent seizure of metal connections is a common problem with assemblies in all industries, particularly so in high-moisture environments in the food industry. When nuts and bolts in the equipment seize up, it makes their disassembly and reassembly a challenge, resulting in unnecessary downtime during maintenance.
According to industry specialist Michael Rowe, who is the Product Manager of Adhesives and Sealants at CBC, using Anti-Seize lubricants while assembling the machinery parts is the best way to avoid maintenance issues down the line.
“There are many reasons why metal assemblies get corroded and seize-up over time. Obviously higher exposure to moisture, heat and pressure accelerates the deterioration of metal assemblies. But by applying the right Anti-Seize products on the bolt treads, the rust and the subsequent seizure can be avoided.”
As a key distributor of lubricants and adhesive solutions in Australia, CBC works closely with Henkel Australia to facilitate the sale of LOCTITE products, with the brand offering a number of safe, metal free Anti-Seize formulations for industries that have safety as a top priority.
But what constitutes Anti-Seize products and why is it important to purchase the right grade of the product for each purpose?
“Anti-Seize lubricants are specialty lubricants that reduce friction between threaded and matted metal parts as well as prevent corrosion and seizure of parts under pressure and at high temperatures. Essentially, they are two‑part systems that comprise of a base grease and special fillers that provide the compound with its Anti‑Seizing, anti-corrosion properties,” explains Michael.
While most Anti-Seize lubricants used widely in industry user copper, nickel, aluminium and zinc, as well as other heavy metals as the filler compound, LOCTITE is among very few brands that offer the metal free formulation.
Stefano Giacometti, Application Engineer at Henkel Australia, says not many people are aware of how much Anti-Seize products have advanced over time and that metal free Anti-Seize compounds can offer the same benefits as the metal-based grades while being safer for the workers as well as for the environment.
“Quite often when I go to a maintenance facility that is using a traditional copper or nickel-based Anti-Seize product, I find that they are not aware that better choices are now available. LOCTITE is at the forefront of introducing new technologies and our portfolio of Anti‑Seize products is a good proof of that,” Stefano says.
LOCTITE portfolio includes six different Anti-Seize formulations, which in addition to the conventional metal‑based Anti-Seize products offer two metal free grades for companies looking to enhance the safety levels at their plants and workshops.
Stefano says the LOCTITE Heavy Duty Anti-Seize functions on all metals including galvanized iron, stainless steel, brass, aluminium and soft metals between -29°C and +1315°C. LOCTITE Heavy Duty Anti-Seize has been formulated to resist higher temperatures than most other anti-seize products on the market.
“The LOCTITE Heavy Duty Metal Free Anti-Seize uses graphite as the solid filler, using this type of Anti‑Seize with stainless steel fasteners, prevents galling from occurring, as this product more effectively lubricates the surfaces. It is widely used in industries where metal-based Anti-Seize use is prohibited or regarded as unsafe. To assist CBC customers in changing out current used copper or nickel based Anti-Seize, the team at Henkel can provide testing on fastening systems, ensuring correct lubricity is achieved to provide correct clamp force for assemblies,” he explains.
The LOCTITE Food Grade Anti‑Seize is another metal free Anti-Seize specifically designed to meet the requirements of food manufacturers, says Stefano.
“Safety is obviously a big aspect in the food and beverage industry. The LOCTITE Food Grade Anti-Seize is NSF H1 rated for incidental food contract and is one of the few such products available in the market,” he explains.
Apart from the choice of the right Anti‑Seize product, Stefano says following health and safety precautions is key to using chemical products safely.
“When you are dealing with chemicals, you need to refer to the material safety data sheet which will tell you what safety gear to use. We are happy to work with our distributors at CBC to help educate our customers on the latest products available for their purposes, as well as to ensure the safe use of these products,” he concludes.
