Producers of hybrid adhesives
COMBINING THE BEST OF MANY WORLDS HYBRID ADHESIVES PICK AND CHOOSE FROM VARIOUS FORMS OF TECHNOLOGY These days, you hear the term hybrid everywhere. For instance, if you want to buy a new company car, you are encouraged to buy a hybrid model. In the parquet industry, too, hybrid adhesives are attracting lots of attention. What are hybrid adhesives? You can compare them to how hybrid cars work. You link the benefits of different forms of technology and you’re on your way. If you consider solely the word hybrid, you notice how it refers to a combination of different forms of technology, silicone, and polyurethane. To be precise, this involves the combination of great strength (PU) and ongoing elasticity. (silicone). This means that such products have a very wide scope of use, often even without the need for a pre-treatment of the substrate. Thanks to their high elasticity, the swelling of materials can be absorbed without compromising on effectiveness.
Comparing is the skill And so, aren’t there any drawbacks? Well, there is the price. That is often somewhat higher, but floor fitters should simply weigh up the benefits and compare them with this drawback. Make sure that you look beyond the first few weeks during and after the fitting. Obviously, any adhesive will adhere well initially, but in the course of time you do notice differences. And so, this raises the question as to whether choosing a cheaper product is always the right choice.
What’s on the market ? Devo
For glueing a wooden floor you have to consider various factors. For instance, do you want to restrict the natural movements of the wood completely or on the other hand do you tolerate them to some extent? What is the nature and flatness of the substrate? What sizes are the floorboards? Do you have to consider floor heating? If so, choosing a hybrid adhesive can be logical as it takes something from everything. The stress is on the so called ‘good’ features, whilst the lesser ones are discarded.
Devo® Glue MSP150 is a semi-elastic, silicone and isocyanate-free hybrid MS polymer adhesive especially for factory-finished, multi-layer stabilised parquet. The adhesive does not contain water, is free of VOC and has excellent spreadability. In its range of MS polymer adhesives, Devo also offers the new high-performance Devo® Glue MS300, a 100% pure MS parquet adhesive that can be used for the most diverse applications, substrates and wood species. Both adhesives are made from Kaneka's original MS polymer raw material. All Devo® parquet adhesives meet the highest quality requirements. In addition to high-performance adhesives, Devo also offers the necessary technical primers for the preparation of problematic substrates. On-site advice, expertise and training are ingrained in the organisation and form the strength of the Devo® adhesive and primer range.
Safe, easy to spread, and high-quality

A number of indicators which hybrid adhesives share can be summarised with the following terms: safe, easy to spread, and high-quality. Safe refers to the fact that producers have considered the floor fitter’s health and the various existing environmental regulations in the different countries. As regards spreadability, we notice that hybrid adhesive producers boast proudly that their products have properties which are just as good as their classic predecessors. We notice there how producers have responded with excellent spreadability, an increasingly long open time, and a longer shelf life.
A hybrid adhesive is by definition an adhesive which uses two different forms of technology. In the field of parquet glueing, a hybrid adhesive is a reactive adhesive which deploys the reactive functionalities of silicone chemistry (alkoxy silanes) to react to the damp and help with the polymerisation of the glue. These functionalities belong to a polymer from a different form of technology than silicones. Hybrid adhesives
Sharing certain benefits Hybrid parquet adhesives share a number of properties (e.g. easy spreadability) in combination with all sorts of benefits. Think, for instance, of the absence of water, solvents, and isocyanates. This means that extra precautionary measures are unnecessary. The benefit for floor fitters is clear and, moreover, the adhesives are often available in ecological packs.
In terms of quality we can say once again that producers are striving for qualitative glueing without a primer on smooth substrates. They’re also paying attention to preventing blistering in the adhesive mass to create a stronger continuous layer of glue. Obviously, they also want

these adhesives to attract as little water as possible to reduce the chances of discolouration and to reduce greatly the chances of sensitive wood sorts curling on substrates with little or no absorption.
