SEAL OF APPROVAL FOR LOCTITE^® 5660

The responses to a new survey reveal that the quality and performance levels of LOCTITE^® 5660 from Henkel are helping users in the vehicle repair and maintenance sector complete a myriad of challenging tasks. Henkel gathered the comments from users who took part in a survey conducted with a nationwide provider of car parts and maintenance/repair services.

The survey is significant because all the respondents purchased and used LOCTITE^® 5660 in real life applications, the extent of which highlights the versatility of this advanced product.

“I used this silicone to seal up a fan switch on an aftermarket alloy radiator, saving me the need to purchase an expensive replacement part,” said one satisfied user. Another stated: “LOCTITE^® 5660 stopped a recurring leak on the oil sump of a 1969 Morris Minor – it adheres to metal really well.”

LOCTITE^® 5660 is a moisture-curing silicone that forms a tough rubber gasket. The thixotropic nature of the sealant reduces the migration of liquid product after application to the substrate. Moreover, LOCTITE^® 5660 has been purpose-designed to offer good resistance against oils and coolants.

Thanks to the product’s excellent adhesive properties, typical applications include transmissions, inlet manifolds, oil pans, valve covers, cooling systems, water pumps, thermostats, timing chain covers and cast metal housings, to list but a few. In fact, the product is suitable for virtually any metal or plastic surface, including those made from mild steel, zinc-plated steel, stainless steel, brass, aluminium, ABS, nylon and phenolic. Large gaps up to 1 mm can be filled.

“I used LOCTITE^® 5660 to seal a water pump outlet connection between plastic and metal surfaces,” said one user, who added: “It made a perfect seal and was easy and neat to apply.” Notably, the product has been specifically designed to provide excellent long-term resistance against water and glycol (antifreeze).

Further application successes reported by survey participants included rocker covers and the sealing of gaskets on a pre-war engine. “LOCTITE^® 5660 can be used with or without a conventional gasket – either way it's an excellent product,” said another user.

Value was an additional theme of the survey comments, which included: “This product is great for the money”, “cheaper than anything I could find online”, “great price”, and “has a good price tag”.

Other common responses focussed on quality and ease of use. “Always good quality,” said one user, while further comments included: “Does its job and easy to use”, and “great product, good sealing qualities, easy to apply”.

And it’s not just car owners who are witnessing the benefit of LOCTITE^® 5660, as confirmed by one survey respondent, who said: “I used the product on a boat’s outboard motor and it sealed the gasket well and easily.”

As a final point of note, LOCTITE^® 5660 can be applied with complete safety in all applications thanks to its leading health and safety features. The silicone is also odour free.
