KERAKOLL’S H40 GEL-ADHESIVES RANGE GROWS
Leyland, June 2023 – Following its launch in 2022, Kerakoll is expanding the H40 range of multi-purpose gel-adhesives, with the introduction of H40 Ultimate.
All four products in the range can be used with any type of tile and all conceivable substrates. H40 Gel is a standard-setting powder form gel-adhesive, and H40 Advanced is a rapid-setting powder form gel-adhesive which offers long working times and accelerated adhesion.
The newest addition, H40 Ultimate is a rapid-setting powder form gel-adhesive with genuine S2 deformability. It is the first of its kind – combining excellent workability with a high degree of flexibility and deformation, ensuring the utmost reliability even on difficult to tile substrates such as wood and metal.
H40 Ultimate is available in Grey and Shock White, as are H40 Gel and H40 Advanced. Shock White’s extreme whiteness comes from a special combination of cements and natural pure white materials which also contribute to the excellent flow properties of the products, and increase coverage and workability. It makes the adhesives perfect for working with light coloured grouts and all types of natural stone and marble.
All three adhesives are easy to spread and holds their shape, supporting the weight of large tiles and stopping vertical slip on walls, making work on site simple. The rapid setting adhesives are non-hazardous to the environment and human health, as the formulation does not include Portland cement and is non-irritating to the skin.
The way that the mix flows means that it fully wets the back of the tile, filling voids, and ensuring a full structural bond, while the fact that it does not dry out means that it does not thicken or allow a film to form.
H40 Extreme, a hybrid gel-adhesive completes the range. This combines extreme fluidity – it is 5 times less viscous than a traditional polyurethane adhesive – with extreme flexibility, as it is ten times more deformable than generic S2 adhesives. It can cope with the most extreme on-site conditions making it the obvious choice for sites with uncommon and/or difficult substrates that cause problems for other adhesives.
Kerakoll’s R&D team has developed their own stringent tests which ensure that H40 gel-adhesives will withstand the stresses suffered by a tiling installation in the real world and not just in laboratory conditions. Samples of a floor bonded with adhesive are subjected to 20 mechanical stress cycles, 50 thermal stress cycles and 50 freeze-thaw cycles, before undergoing tensile and shear strength tests to measure the strength of the bond. All four H40 gel-adhesives pass these tests with flying colours due to the strength of the adhesive bond.
The range really is universal: suitable for use on all substrates and in all situations, be it in residential or heavy duty commercial settings, internally or externally. Externally it can even be used on areas subject to significant temperature changes and in constant exposure to water.
