LONDON, UK / AGILITYPR.NEWS / June 25, 2020 / If ever the vehicle maintenance and repair sector wanted confirmation of the quality of LOCTITE^® 5990 silicone sealant from Henkel, then a new survey conducted in conjunction with a nationwide retailer of car spares and maintenance/repair services provides the evidence. Indeed, the comments gathered from users of this premium product reveal the high performance levels being achieved across a host of car and motorcycle applications.

Exhaust repairs, one of the most common bugbears for motorists, feature heavily in the responses. For instance, one user said: “I used LOCTITE 5990 on a Smart Fortwo CDI after replacing flexi pipe. I would certainly recommend it over any exhaust paste, which tends to get brittle with age.”

Another reported: “Having tried many exhaust sealing solutions, I can guarantee that LOCTITE 5990 is by far the best. Its superior bonding and heat resistance are fantastic, and has never let me down. I highly recommend this product and will continue to use it.” This particular user, who is from the East Midlands, gave it 5 out of 5 for quality, value and performance.

A fellow user from Wales, who gave LOCTITE 5990 the exact same score, stated: “I used the product as a sealant on the inlet and exhaust manifold gaskets of my Mitsubishi Pajero 2.5 TD, and I couldn’t be happier. Perfect product and a very good price.”

Offering excellent adhesive strength, LOCTITE 5990 is ideal for use on a vast range of metal, plastic, coated and painted surfaces (and combinations of each), and for applications involving large gaps up to 1mm. Delivering high temperature resistance up to 350°C, this non-corrosive silicone sealant cures on exposure to moisture in the air, forming a tough rubber gasket.

“I would definitely recommend this product – my exhaust was blowing from two joints, but after applying LOCTITE 5990, it was silent,” said one survey participant. Another provided an equal level of satisfaction: “I had an exhaust leak between the turbocharger and catalytic converter on my Peugeot 307 SW. To fix it, I removed the catalytic converter, cleaned the surfaces and sealed it with LOCTITE 5990, before re-joining with new clamps. All OK after 1000 miles to date.”

And yet LOCTITE 5990 has far more uses than simply exhausts, as the following comments suggest: “It worked a treat on a timing chain cover for my V8 when rebuilding a competition Drift truck,” said one customer, while another reported: “A month later and no leaks from my oil pan. I would recommend.”

A user in Burnley, who gave the product 5 out 5 for quality, value and performance, stated: “I used LOCTITE 5990 to put an oil sump back on to a 2005 Nissan Micra 1.2. The product worked really well.”

Of course, car owners are not the only ones to benefit from the characteristics of LOCTITE 5990, as a raft of motorcyclists responding to the survey, revealed. One said: “I applied this product either side of copper washers at banjo unions on my bike’s oil cooler. A superb first-time fix.”

Another motorbike owner reported: “I used LOCTITE 5990 on a 1978 Triumph T140V instead of fiddly paper gaskets, and as additional sump plug seal with respective copper washers. No leaks after a year. Highly recommended.”

Ease-of-use is a major benefit of LOCTITE 5990, which is a one-part product that can replace pre-cut paper or cork gaskets. Of particular note, the thixotropic nature of the sealant minimises liquid migration after application.

“This is a nice, easy-to-apply product that comes with a convenient metal spreader tool,” said one comment.

LOCTITE 5990 has also been designed to offer high levels of oil resistance, making it suitable for use on flanges with permanent oil contact. Meeting the performance specifications of OE silicone gaskets, this low-odour product can fulfil virtually all repair and maintenance requirements.

“Good product that did exactly what I wanted it to,” said one user, who added: “I couldn't do the job without it.”

In short, LOCTITE 5990 is an optimum solution for sealing any mechanical components exposed to high temperatures, including exhaust systems, turbocharger housings, oil pans, valve covers, intake manifolds, timing covers and differential housing covers, to name but a few. Remaining permanently elastic, the sealant is extremely resistant to external stresses, and can also be used for electrical insulating applications, providing yet another indicator of the product’s versatility.
