The advantage of polyurethane foam raw material
1. The solid content of 100%, no volatile, non-toxic, conform to the requirements of environmental protection
2. The excellent physical properties such as strength, hardness, toughness, hardness is adjustable
3. The compact coating, anticorrosive, waterproof, wear-resisting performance is remarkable
4. Strong weatherability, outdoor use for a long time not crack, not pulverization, not an omission
5. In steel, aluminum, concrete, wood, plastic and other kinds of all have good adhesion on
6. Good thermal stability, can be long-term use under 150 °C, can withstand the temperature of 250 °C
7. To join various pigments, fillers, made into different colors of different characteristics of products
8. Is not sensitive to humidity and temperature, the construction strong adaptability to environment
9. Fast curing, construction not sag;Can a construction requirements, short construction period
After construction is easy to repair the jointless, beautiful and practical

FIRST AID FOR EYES & SKIN
When working, please avoid contact of polyol with eyes or skin. Safety glasses are suggested Skin contaminated with polyols should be washed with soap and plenty of water. If polyol contacts eyes, flush with plenty of low pressure flowing water or get medical attention.
Theoretical amount of polyurea coatings:
Recommended film thickness is about 1.5-2.5mm, estimated consumer consumption amount for 2.0-3.0kg/square meters, the amount of nodes, corners and some special parts may than theoretical consumption greater. The shortest, time is not limited; The longest, no more than 3 hours
Application
Suitable for: all kinds of building roof waterproof leakproof and bridge, reservoirs, tunnel and underground engineering and power plant cooling tower, water tank, aquarium, swimming pool, etc. Lining concrete structure
Not only widely used in ordinary engineering waterproof construction, but also can be used for difficult waterproof engineering, such as municipal construction of underground waterproofing, the tunnel seepage control and all kinds of corrosive sewage treatment area of ditch, the pool of waterproof anti-corrosion engineering construction.
