DESMOFLEX® CATALYST

The DESMOFLEX® CATALYST is a reaction accelerator suitable for use in combination with DESMOFLEX® PU. It is used when the application will take place at low temperatures, when a thicker layer is required or to reduce the waiting time between the application of each layer. With the addition of the DESMOFLEX® CATALYST, the homogenous polymerization of the waterproofing membrane is accelerated and as a result, the next layer can be applied after 4-5 h, even in conditions of low humidity. At the same time, the formation of air bubbles is prevented, and mechanical strength is increased.

• Enhances the mechanical properties of the final mixture, making it suitable for the most demanding construction sites.

• Accelerated, homogenous polymerization of DESMOFLEX® PU
• Rapid polymerization of DESMOFLEX® PU at low temperatures
• Curing in low humidity conditions
• Application of the next layer after 4-5 h
• Thicker application layer without air bubbles forming
• Increased thixotropy of the final mixture
• Does not significantly affect the workable time of the mixture
• Enhances the mechanical properties of the mixture
• Non-toxic for the environ-ment or humans
• Does not degrade after initial unsealing

• Stir the DESMOFLEX® CATALYST then add 3% w/w to the quantity of DESMOFLEX® PU which will be applied.
• Stir the mixture with the help of a drilling machine (300 rpm), for 2-3 minutes until it becomes homogenous. During stirring, the drill should be moved close to the walls and bottom of the vessel in order to evenly distribute the accelerator in the mixture.
• The mixture should be used immediately after mixing and within 15 – 25 min on the properly prepared surface. After this time the mixture shall be discarded.
