Threadlocking adhesives upgraded

To meet the requirements of engineers and designers and to facilitate use on a wider selection of substrates, Henkel has improved the formulations of two of its most popular threadlocking adhesives.

Medium strength Loctite 243 and high strength Loctite 270 are said to be more oil tolerant than previous grades, enabling them to be used more readily on 'as received' parts – including those contaminated with engine oils, corrosion prevention oils and cutting fluids. Their temperature resistance has also been increased to 180°C and the adhesives will cure not only on active substrates, such as iron, copper, brass and steel, but also on passive materials including stainless steel, aluminium, nickel and zinc plated surfaces and chrome-free, inorganic and organic coatings. Colin Chapman, marketing manager at Henkel, said: "It is part of our ongoing strategy to both anticipate and meet the requirements of engineers throughout industry. The introduction of these two improved products permits engineers to employ top quality anaerobic threadlocking adhesives in a much broader range of applications than has been previously possible."
