Water tanks are vital structures where we safely store our drinking water. Therefore, choosing the right insulation material is of great importance to extend the life of the tanks and protect the quality of the water. In addition to traditional methods, today there are new generation insulation materials that do not react chemically when in contact with water and are long-lasting and flexible. Water tank insulation material DF Pur WT 2K is a material specially designed for waterproofing. It protects water quality by preventing any harmful substances from entering the drinking water and at the same time preventing unwanted formations such as moisture, bacteria and algae in the tanks.

Protective equipment such as goggles and gloves should be used during application. In case of eye contact, wash thoroughly with plenty of water. Request Material Safety Data Sheet for detailed information. Keep out of the reach of children. The product should be consumed by professional users, taking into account the data in the technical information section.
Application Features
- Surface Preparations: The surface should be cleaned, if possible using a high pressure washer, removing oil, grease, fuel and paraffin residues, as well as mold release agents, cement residues, chips, loose particles and cured membranes.
- Priming DryFiX DFC-100 Epoxy Primer is recommended.
- Mixing Components A and B are mixed in a low speed mixer for min. 2-3 minutes. Mix and make ready for use. The usage time of the prepared mixture is 20-30 minutes at +20 °C. Depending on the change in air temperature, the usage time may be shorter or longer.
- Application: The material should be applied to the pre-primed surface with a roller or brush until the entire surface is covered, by pouring on the floor, min. It should be applied in two coats, and in vertical applications, it should be applied in min. It should be applied in two coats. After the first coat is applied, min. 8, max. 24 hours after the first coat is applied.
