Making the right choice made easier


Product selector visual

I’ve talked and talked and talked about how to choose the right adhesive for your application and emphasised time and again how important it is to get expert help in making this decision. I’m coming back to this topic because Loctite now has a tool that can make this process considerably shorter for you. You will still need to contact an expert and likely test the product at the end, but instead of reading through pages and pages of technical data in search for the answers, you can “tell” what you need to a simple digital selection tool by answering some simple, but specific questions: which substrate you want to bond to which other substrate, what kind of strength is required from the assembled parts, do they need to withstand high temperatures, are they subjected to static loads or is there movement, how quickly do you need the adhesive to cure or what kind of a gap needs to be filed. It takes only a few minutes, and apart from English, it’s available in several other languages you can choose from.

Wishing you a happy search!

The Hybrids



Apart from the fact that they can pull trains, carry trucks and tractors, perhaps it’s time I said a few more words about what hybrid adhesives really are and what makes them special.

Like many other human inventions, hybrid adhesives came to be as a reaction to the need or, if you will, a problem that needed to be solved. Generally, in the world of bonding there are two main sides of what adhesives can do. On one side there are instant adhesives, based on cyanoacrylate technology, which are easy to use, bond really fast and are therefore known also in consumer, household use and by do it yourself-ers as the so called super-glue. They have their rightful place also in engineering, due to their safe and simple use, quick curing and high performance on plastics which are nowadays one of the most common materials in industrial use. However, they lack in flexibility and gap filling properties.

On the other end of the scale, are so called structural bonders. In terms of chemistry, they can be epoxy, acrylic, polyurethane, silicone or SMP (silane modified polymer) based. Their strongest traits are, apart from excellent structural performance that gives the range the name, high gap filling properties, excellent performance on metals and environmental durability.

From everything said, it’s fairly obvious that the two ranges of adhesives will be used in practically opposite situations. But naturally, the engineering reality doesn’t always fall into one of these two extremes. There are certainly cases when you might need to fill a small gap, while you still need the adhesive to cure fairly quickly. Plastic does not always get bonded to other plastics, sometimes you need to bond it to a metal or a composite material, and you’ll need your part to be durable and resistant to environmental influences.

This reality is what the chemists in Loctite research & development had in mind when they created the first hybrid adhesive. Not only did they succeed in creating an adhesive that has structural and environmental durability, universal adhesion to multitude of substrates and cures fast through high gap, but they also managed in making it one of the safest adhesives to handle in terms of minimised health hazards.

You can choose from several Loctite grades, depending on whether you’re designing something new or repairing existing parts.



Adhesive that pulls a train!


Train hybrids blog

Now, I’m absolutely aware that there is probably not one single realistic situation in which you would need to pull a train using a rig which is held together by adhesive. But we did it. Why? Because we can :-)! Don’t take my word for it though – see for yourselves.

And here’s how that was done.

The product that was used is a Hybrid adhesive. In adhesive world this means that it combines properties of two chemical components, in this case: cyanoacrylate and methyl methacrylate, and sort of combines the best of both worlds: speed of curing typical for cyanoacrylates and strength and durability typical for MMAs.
