New Anti-Seize Paste Seizes the Initiative

Secure screw connections, and surfaces which slide smoothly even under high stress, are essential elements of most industrial assets. But countless maintenance engineers have come to service or repair an assembly, only to find that – even when a connection was tightened to the correct torque – it’s impossible to dismantle easily. And many sliding surfaces seize all too quickly under high loads or stresses. 

The traditional solution has been to use an anti-seize paste: also known as an assembly paste. However, these most traditional and effective solutions have tended to contain a level of copper which requires them to be labelled as toxic in a marine environment, and handled and used accordingly. As its name suggests, the new OKS 7240 Copper Paste contains copper for its effective anti-seize qualities. But its innovative low-copper formulation not only frees-up screw connections. It frees-up usage restrictions too.

From factory to fish farm

Unless your site is on a riverbank or the coast, you may think the marine environment isn’t your problem. But marine toxicity of anti-seize paste isn’t just an issue for fish. 

If you wash-down equipment, the water you use will eventually make its way to the drains and ultimately to a marine environment. Which means you have to take responsibility for meeting safe handling and usage requirements. 

The benefit of new OKS 7240 paste is that it’s lost its marine toxicity without losing any anti-seize effectiveness. So you can use it in a factory, and even in a fish farm.

Anti-seize properties have traditionally been provided by solid lubricants – usually copper – within the paste. Long after the oil in a lubricating grease has disappeared, these solid lubricants are still present, and still preventing sliding surfaces from seizing and screwed connections from burning- or rusting-on. In OKS 7240, copper is still an ingredient, but it achieves the best of both worlds. It’s: 

■ at low-enough levels to eliminate marine toxicity labelling requirements, and
■ in sufficient concentration to be a highly effective anti-seize paste.

When the going gets tough

In an aggressive operating environment, any likelihood of seizing, rusting or burning-on will be many times higher than under more normal working conditions.

However, OKS 7240 not only aids lubrication and separation, but does so at temperatures of up to 100°C 
for lubrication and 1,100°C for separation. It also meets DIN EN ISO 9227 salt spray test requirements, and is certified to DIN 51 350-4 in wear protection tests.

In fact the only thing that isn’t tough about this new OKS anti-seize copper paste is getting hold of it. Just speak to your usual ERIKS contact.
