Spray polyurea coating SPUA-DHK3100
SPUA-DHK3100 is a 100% solid, fast set, spray-applied, two component aromatic polyurea elastomer. The system consists of the A
component, a quasi-prepolymer rich of free NCO, and the B component, a mixture of polyetheramine, amine extenders and other
additives. The unique polyurea chemistry allows this material to be tolerant of moisture and lower temperatures during
application. This means that high humidity and hidden moisture in concrete has minimal effect on the application of this product.
* Fast cure, short downtime but non-sagging.
* Moisture and temperature insensitivity during processing.
* High thermal stability.
* 100% solid, Non-VOC and odorless, environmental friendly.
* Extraordinary physical properties.
* Excellent adhesion to primed concrete.
* Seamless, flexible and waterproof.
* High elongation properties, resistance to freeze-thaw.
* Superior weather resistance.
* No chalking and fading in long-term outdoor use.
2. Application
Designed for use as a smooth seamless waterproof lining coating system for interior and a roof and wall coating system for
exterior applications. Ideally suitable for use in areas including:
Metal, concrete, wood and foam roofing.
* Mechanical rooms.
* Cold storage areas.
* Basing and reservoirs.
* Marine bridges.
* Tunnels.
* Underground engineering.
* Cooling towers of power plants.
* Aquarium lining.
* Pond lining.
* Water and waste water linings.

5. Recommended Primers
Concrete
SPUA-DHK400 sealing primer @8-10sqm/ kg per coat
Others: contact us for a recommendation
6. Packing
Part A: 220kg /drum
Part B: 200kg/drum
7. Storage condition
* A component is easily affected by moisture must be protected from moisture contamination. Containers are factory sealed with an
inert gas to prevent contamination. Keep all containers tightly closed during storage. For further storage after opening,
containers must be purged with nitrogen gas or dry air and tightly sealed from moisture.
* Store drums and pails in a cold, dry and ventilated location between 15-40°C.
* Keep away from rain and sunshine.
* Keep away from fire and heat source.
