Application :
These are applied by plural component airless spray equipment. It is ideally suited for the areas where higher DFT build is required as a protective barrier. The coating has excellent film build capabilities and can achieve 500 microns to 3000 microns DFT in single application with multiple passes.
Polyurethane coating :
1.are nonflammable, solvent free and as safe as house paint
2.can be put into service within hours
3.are easily touched up if damaged
4.are non-dangerous goods for transportation
5.require no post curing
Application Areas :
~ superior adhesion
~ resistance to chemical attack
~ resistance to abrasion
~ flexibility and resilience
~ impermeable
~ resistance to disbandment forces
Uses :
High build Elastomeric Polyurethane Coatings find uses in critical structures such as:
- Storage tanks,
- Mounded bullets,
- Reservoirs, overhead tanks,
- Marine and off store structures.
- Internal and external linings for pipelines,
- Concrete tunnels and thermal power cooling towers.
