Water-based epoxy sealing primer

Product advantages:

Solid state waterborne epoxy sealing primer base material with good affinity with concrete, can easily penetrate the concrete internal, paint film is exposed to air and moisture in the basal in acidic and alkaline environments under the action of ring opening reaction, generate hydroxyl groups. The hydroxyl group will be crosslinked with base material and its accumulation, combining on the inner wall of the pores, eventually form a layer on the surface of wool stoma in concrete strong hydrophobic organic network layer, and can effectively prevent the invasion of external moisture and harmful substances, and make the internal moisture and harmful gas escape, thus greatly improve the water proofing property of concrete structure, salt resistance, freezing-thawing resisting sexual features, with fewer coated quantity can achieve excellent results, keep the natural appearance of concrete, concrete capillary water absorption, greatly reduce significantly reduce the chloride ion erosion, freeze-thaw damage, steel corrosion and mould growth, excellent chemical resistance, weather resistance, abrasion resistance, contamination resistance, self-cleaning effect, keep the permeability of concrete, excellent penetration depth, prolong the service life of reinforced concrete for more than 20 years.

Application:

It is widely used in concrete surface coating and various reinforced concrete structures such as seaport pier and cross-sea bridge.

High bridge, highway bridge, coastal railway bridge, tunnel, airport runway, thermal power, nuclear power plant and other concrete structure protection.

Product parameters:

Small yellow transparent liquid.

The storage period is 12 months.

Packing iron drum: a group of 18kg; Component b 9 kg

Notes:

1. Match before use, and should be finished within 4 hours after match, otherwise it will be dry and thickened.

2, concrete should be in curing period (28 days) before construction, construction of concrete surface temperature should be between 5-45 ℃.

3. This product belongs to inflammable goods. Safety precautions should be taken care of, and the construction site should be well ventilated, away from sparks, heat sources and open flames.

4. Operators shall use necessary safety protection facilities.

5, most of the paint in the construction of the 4 hours after that the total absorption of concrete, before that have been impregnated silane concrete to avoid contact with water, and the complete reaction of the epoxy and concrete to form epoxy resin network need to 24 hours.
