Regardless on whether your building is being heated or cooled, thermal insulation offers the greatest opportunity for saving energy.  And within the class of insulation products, rigid urethane foams are still the most common type of insulation used in residential and commercial construction applications.

Rigid urethane foams are not new. The earliest systems which were based on TDI chemistry were first made by I.G Farben in the mid 1940’s. At that time, the main technical difficulty with them were health hazards associated with their processing. It was not until the early 1950’s, that Imperial Chemical Industries (ICI) in the UK, developed lower toxicity systems based on the now familiar TDI chemistry.

By far, the most common application for rigid urethane foams in Ireland, is in the manufacture of so called slabstock foams for construction applications. The manufacture of slabstock foam is a pretty complicated process. The bulk polyol and isocyanate, together with ancillary chemicals such as blowing agents, catalysts etc, are metered into a mixing head which is placed over the facing material. The resulting mixture is dispensed continuously onto the facing material, which may be paper or a paper/foil laminate. The foam expands greatly within ten or so seconds, after which, the resulting sheet is cut to size.

If you want to glue a rigid urethane foam to an absorbent material, such as the aforementioned plasterboard, plywood or OSB, we typically suggest one of our solvent free waterbased adhesives. Using either manual or automatic rollers, the adhesive is applied to one side of the material being glued. After approximately fifteen minutes, the laminated sheet may be moved to another processing area.

We produce a range of water based industrial glues. Our W96, W286, W300-HV and W300-LV, have set the standard for a range of non-toxic eco-glues. Designed for roller or spray applications, these glues offer the insulation professional glues which are exceptionally easy to use. But it doesn’t stop there. Our Engineers have in the past, designed application equipment to suit specific requirements, the full turnkey service!

For gluing rigid urethane foam to non-porous materials such as PVC coated steel, either a solvent free polyurethane glue or a solvent based glue is typically used. Our solvent free polyurethane glues, such as DP 462 and DP 463, are used to bond urethane foams to plastisol coated steel, aluminium and various composites. For use, the glue is applied by roller or serrated trowel. The materials are brought together and allowed to cure. Cure times range from fifteen to twenty five minutes. These laminates find typical use in the manufacture of prefabricated buildings.

Solvent based glues are used in some specific applications, particularly in retrofit applications, where the glue is daub applied onto certain opposite areas of the urethane foam and rigid structure.

As well as having superior performance properties, our glues are designed for use in a very range of construction applications. Further challenges are on the horizon. Environmental compatibility, living closer together and finally aesthetics, are all aspects of construction that we continue to work on. Let us be your insulation glue partner.
