New binder technology for 2K fast curing waterproofing membranes
The fast curing of a membrane is an important attribute for the waterproofing market because it offers the applicator the possibility to apply a second waterproofing layer and go to the following step in the construction within the same working day. A new generation of latexes developed by Dow Construction Chemicals combined with a fast curing drymix helps achieve very good waterproofing performance at standard and high pressure, very high flexibility and crack bridging, as well as elongation retention after water swelling.
A drymix formulated with fast cement and combined with standard latex results in a very short pot life mortar and a membrane that lacks flexibility and very often has cracks and hence is not waterproof. The new latexes provide long enough pot life to allow good workability and still enabling the application of a new layer on top of the first layer within 0.5–2 h. This new technology will provide the waterproofing market an environmentally advanced option for both interior and exterior applications.
