Global lubricant leader Molyslip, has removed all calcium compounds from its entire range of anti-seize lubricants, ensuring that its products are safe for operators to use in all environments*. By removing calcium from Ceramslip and Ferroslip, Molyslip has become the first company to have a 100% calcium free anti-seize range. The move removes any risk of exposure to carcinogens from anti-seize compounds that have been found at high temperature operating conditions, whilst maintaining the high-performance that Molyslip customers associate with its products.

Ceramic AntiSeize

Our main goal is always the safety of our customers’ remarks Andrew Cunningham, Commercial Manager ‘we are extremely fortunate at Molyslip to have state-of-the-art laboratories with chemists leading the field in lubricant technology.  We can therefore react quickly when safety issues like Cr(VI) are raised.  Our priorities are two-fold – the best possible product for the job but never at the risk to our users.’ He adds: “Many anti-seize lubricants in the market still contain calcium but I’m proud that our customers can use our Molyslip range with peace of mind.”

Calcium has traditionally been used as a high-temperature anti-seize solid. Both Ceramslip and Ferroslip benefit from the change in formula, where calcium has been replaced by newer additive technology giving our products higher performance capabilities.

High temperature anti seize compound grease and lubricant Molyslip Copaslip

* As highlighted in recent Energy UK Safety bulletin, carcinogenic Hexavalent Chrome Cr(VI) can occur when 3 specific parameters are simultaneously satisfied:

  1. Calcium based product is present
    • Temperatures greater than +300 °C
    • Chrome steel is present
