Gunite GPU high-performance polyurethane mortar floor system is a four-component waterborne polyurethane mortar floor material, which has all the advantages of organic polymer and inorganic concrete materials, such as excellent chemical corrosion resistance, heavy impact resistance and thermal shock resistance. Suitable for various harsh environments with special performance requirements.

Typical performance: especially wear-resistant, moisture-proof, non-slip, resistant to harsh chemical corrosion, heavy load and strong impact, environmentally friendly and pollution-free, with a service life of more than 20 years, resistant to high and low temperatures of -40℃~ 130℃, and widely applicable to various durable and clean ground places.

Application place: It can be widely used for ground treatment in extreme working environments such as food/slaughter/heavy antisepsis/high humidity and high temperature, and all floors that need wear resistance/cleanliness/chemical corrosion resistance such as workshops/warehouses/garages/laboratories. It has incomparable advantages over traditional floor coatings such as epoxy/emery/two-component polyurethane, and it is a floor product with excellent comprehensive performance in global floor applications at present.

Product introduction

Permeability function of water molecules

Waterborne polyurethane and activated cement-based inorganic materials have good hydrophilicity, and at the same time, the special concrete floor structure formed by the condensation of four components can be infiltrated by water molecules in one direction, which can effectively reduce the foaming and delamination of the floor caused by water vapor at the grass-roots level. It has the following excellent properties:

Architectural performance

1) no primer coating, rapid curing, 20℃ construction environment temperature, 8 hours pedestrian, 24 hours driving.

2) In the absence of a very dry concrete base (moisture content > 10%), the construction can be carried out on the new concrete that has been cured for 7 days.

3) There is almost no smell in the construction process, which is beneficial to the health of operators and the prevention of environmental pollution.

mechanical properties

Outstanding compressive strength, flexural strength, especially impact resistance, toughness and high elastic modulus, and no cracking caused by brittleness of materials has ever occurred; The adhesive strength is good, so it has good delamination prevention and crack resistance.

High and low temperature performance

1) can be used normally at -40℃ ~+ 130℃ for a long time, and there is no abnormality when soaked in hot water at 60℃ for a long time. 9mm thick floor can resist the continuous erosion of boiling water. If the floor with a thickness of 12mm can withstand short-term thermal shock of 150℃ and can withstand complete steam washing. Floor tiles can't resist such thermal shock.

chemical property

Resistant to corrosion of most inorganic and organic solutions; It has good corrosion resistance to solvents, inorganic acids, organic acids, lactic acid, oleic acid and fruit acid.

85% lactic acid (60 degrees) dairy products

100% oleic acid (60 degrees) fat

95% alcohol

50% citric acid juice

50% sodium hydroxide cleaner

30% nitric acid cleaner

15% sodium hypochlorite

paraffin
