2. Why you need Delta Polyurea containment lining system?

  • Because Delta Polyurea is resistant to many chemicals and industrial liquids.
  • Because Delta Polyureas containment lining are great for extending the life of older tanks and can offer limited structural characteristics as well.
  • Because of Delta polyurea fast application advantages and excellent adhesion to prepared substrates , Delta Polyurea containment lining are ideal for new storage tank primary lining and rehabilitation projects.

3. What Chemical can Delta Polyurea resist?

Please refer to Chemical Resistant Chart.

4. What Tempreture can Delta Polyurea resist?

Delta Polyurea can resisit Up to 80⁰ C

5. What type of containment substrate can Delta Polyure applied?

Delta Polyurea can be applied on steel and concrete containment.

6. Will Delta Polyurea Crack due to the movement of the containment?

No, it has an elognation property up to 600%.

7. What is the difference between PU and Polyurea?

Polyureas are closely related to polyurethanes. Both are two component systems made with Isocyanate-based materials. However, while the second component in polyurethane is polyol resin, the second component in polyurea is a polyether amine.

In terms of performance, conventional polyurethanes require a catalyst, which is sensitive to temperatures and moisture. Low temperatures can slow the reaction and moisture can interfere with the reaction causing blistering and other negative effects. Polyureas, on the other hand do not require a catalyst. Reactivity for these coatings is fast, typically 3-10 seconds. Consequently they are able to cure at temperatures as low as –20 C and in the presence of moisture.

8. What is the difference between Epoxies and Polyurea?

In terms of performance, unlike polyureas, epoxies require a catalyst. They are sensitive to temperature, humidity and moisture, giving them a narrow window for application. Unlike polyureas, epoxies have extensive cure time and little or no elongation properties. This leads to frequent failure of the coating with expansion or movement of the substrate.
