Product Description
PUR 870 is a specialised, high-performance polyurea coating designed and developed to protect buried and exposed structures. It is an excellent choice where increased tensile strength is required. Applicable in various industrial facilities including power, manufacturing and mineral processing, PUR 870 is a two-component, 100% solids hybrid polyurea with tensile properties that outperform typical coatings used in industrial applications. This aromatic polyurea elastomer shows good resistance to a wide range of chemicals, including hydrogen sulphide and methane, and offers excellent thermal stability, abrasion resistance and UV resistance.
Application Areas
- Sprayed PIP structural replacement liners for concrete and steel pipes
- Erosion, abrasion, vibration and control applications
- Concrete structures where higher tensile and tear properties are required
- Carbon fibre infill applications for structural strengthening
- Mining slurry lines
- Sludge catchers
Advantages
- 100% solids with zero VOC
- Curing time providing fast reactivity and almost immediate return to service
- Operates at constant temperatures from -40 °F to 250 °F (-40 °C to 120 °C)
- Retains its physical properties under weathering
- Excellent elongation and tear properties
- Puncture resistant
- Excellent corrosion protection
- Excellent abrasion resistance
- Excellent thermal stability
- Resistant to many solvents, acids and alkalis
Application
This material must be applied using high-pressure, heated, plural-component spray proportioning equipment. The proportioning equipment used must be able to consistently provide the correct pressure and heat for the appropriate hose length.
For optimum performance, the substrate shall be abrasive blasted. Concrete substrates should be allowed to cure for at least 30 days.
