Leverkusen, Germany – Covestro has worked with Polish construction materials specialist Selena to create a bricklaying adhesive with a significantly lower carbon footprint than traditional cement mortars. Tytan Professional Adhesive for Bricklaying is claimed to cut the footprint by up to 90%.
The adhesive uses Covestro’s mass-balanced Desmodur CQ MB bio-based MDI. The demand for more sustainable building materials is set to rise in the light of the EU’s recent update to the Energy Performance of Buildings Directive. This requires all buildings in the EU to meet net-zero emissions standards by 2020; about three-quarters of European buildings do not currently meet energy efficiency requirements.
It can be used with various types of blocks, with a higher yield than cement mortars. It is also said to improve construction efficiency by curing twice as fast, and has an operating temperature range of -5°C to 30°C, helping to reduce temperature-related work stoppages.
“Materials play a decisive role for an ever more climate neutral and circular economy”, said Bernd Hennig, head of Covestro’s MDI trading cluster. “If materials providers early in the value chain join forces for climate neutrality, the impact on end products will be significant. In this spirit, we are therefore very happy to deepen our collaboration with our like-minded partner Selena to help the construction sector bring down emissions and meet its climate neutrality targets in Europe and worldwide.”
This is the third product launched from a collaboration between the two companies. Desmodur CQ MB MDI is already used in a version of Selena’s Ultra Fast 70 one-component foam for window and door installation.
