Description
The Action Can CS-90 is a copper anti-seize paste made to protect threaded fasteners from seizing, galling and corrosion, even where temperatures run high. It carries a high copper content along with professional grade inhibitors that guard against rust, seal out moisture and shield threads in harsh, corrosive settings. The 500g size suits regular workshop and maintenance use.
We rate this paste for the way it keeps components working together over long service intervals. It reduces friction and wear, prevents stripping of threaded fasteners, and makes both assembly and disassembly easier when the time comes to strip a joint down. The film is non-hardening and non-dripping, so it stays where you put it rather than running off the work.
CS-90 is water resistant, which helps hold back the moisture that starts corrosion in exposed joints. It is free from lead and silicone, a point worth noting for applications where silicone contamination is a problem. Common uses include exhaust bolts, brake fittings, spark plugs and any high-temperature fastener that needs to come apart again later. Apply a thin coat to clean threads before assembly for the best result.
Specification
Frequently Asked
What is CS-90 copper paste used for?
It protects threaded fasteners from seizing, galling and corrosion, and is often used on exhaust bolts, brake fittings, spark plugs and other high-temperature joints.
Does it contain lead or silicone?
No. CS-90 is free from both lead and silicone, so it suits work where silicone contamination needs to be avoided.
Will it harden or drip over time?
No. It forms a non-hardening, non-dripping film that stays in place through extended service intervals.
Is it water resistant?
Yes. The paste is water resistant, helping to seal out moisture and hold back corrosion on exposed threads.
How should I apply it?
Apply a thin, even coat to clean threads before assembly. This aids easy disassembly later and protects against seizing.
What size is this tin?
This is the 500g size, suited to regular workshop and maintenance use.
