Double Component Spray Polyurea Coating for Mining Equipment

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.
•  

The polyurea elastomer coating now has many advantages over the earlier developed polyurethane, polyurethane \ polyurea technology:
1. Curing speed, in the vertical plane will not produce sagging, cross-linking speed of 2-6 s, 6-9s can reach the level of non-stick hand, 30s can walk on it. 30min to put into use.
2 is not sensitive to temperature and humidity, high humidity and low temperature on the polyurea elastomer coating performance is quite small.
3 100% solid content, two-component coating, single coating system, spray coating can reach a fairly thick 2000UM above, without solvent, zero VOC.
4. Outstanding physical properties, tensile strength 14-21MPA, stretching 2% - 520% between.
5, heat resistance, thermal stability of 177 degrees, (350T)
6. Compatibility with the pigment is very good, you can adjust the color.
7. Adjustable formula, from soft to hard polymer coating.
8. Can be enhanced, in the spraying process can be added to enhance the glass fiber.

Technical data

 
Performance characteristics

 Packing

Part A: 220kg /drum

Part B: 200kg/drum

 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.

Installation instruction

a. Surface preparation

Surface must be properly prepared. Remove all oil, dust, grease, dirt etc to ensure adequate adhesion.

USED IN ANY PLACES FOR ANTICORROSSION, ANTIABRASION, ANTIWATER,ANTISLIP, LOWER NOISES!


HOW TO APPLY POLYUREA?
Highly-skilled professional contractors are required for successful projects.

WHEN COATING WITH POLYUREA?
There are two rapidly reacting and curing components that need the right conditions in order to achieve the desired outcome.

• Special two-component spraying equipment required.
• Typically hot-sprayed at 70-85°C.
• Due to the curing time of a few seconds, there is no room for errors.
• Personal protective equipment necessary.

• Complete polyurea system from sealers, primers and hardeners to topcoats
• Local technical service, support and practical training
• Partner with comprehensive corrosion protection knowledge gained through 70 years
