Polyurethane
Description:
It is a kind of macromolecule chemical thick liquid. When
meeting water, crosslinking happens that lengthening molecular
chain, increasing viscosity, releasing CO2, the thick liquid
expanding and dispersing all around into cracks or holes and
finally comes into being a solid of anti-corrosion and good
adhesion. It is approved, by wide customers, to be an ideal
water proof and anti-corrosion product.
- This product is in three types: grouting (TT), coating
(TP), anti-corrosion (YJ)

Uses:
1. Grouting(TT): For water proofing and blocking leakage of
underground engineering, for example, in selective water blocking
and permanent well-sealing in underground tunnel and petroleum
mining, or solidification of foundation and railway, wharf,
pier, etc.
2.Coating (TP): for leakage repair and anti-penetration. For
example, in water tower, cooling tower of power plant, subway,
etc. or indoor floors of hotel, office, warehouse etc.
3.Anti-corrosion(YJ): for anti-corrosion of metal container,
concrete building surface, various pipeline fittings, or drinking
water protecting material.
Packing and storing information:
- 1. 200kg iron drum, 25kg plastic drum.
2. sealed and stored in cold and dry places, shelf life
is 6 months.
3. it is forbidden to contact with water and air to avoid
skinning and curing.
