The difference between polyurea anti corrosion and epoxy coal asphalt anti corrosion

Polyurea antiseptic features:

1. No catalyst, fast curing, can be sprayed on any curved, inclined and vertical surface, no flowing, 5 seconds of gel, 1 minute to reach walking intensity.

2. It is not sensitive to moisture and moisture, and is not affected by ambient temperature and humidity during construction.

Two-component, 100% solids, environmentally friendly;

The thickness requirements of one construction have overcome the disadvantages of multi-layer construction in the past.

5. Excellent physical properties, such as tensile strength, flexibility, aging resistance, medium resistance, wear resistance, etc.

6. It has good thermal stability, can be used for a long time under 150 degrees, and can withstand short-term thermal shock of 350 degrees.

7. Various colors and fillers can be added to make products of different colors.

8. The formula system can be adjusted arbitrarily, and the feel ranges from soft eraser (Shaw A30) to hard elastomer (Shaw D65).

9. The use of complete sets of spraying and pouring equipment is convenient for construction and high efficiency.

Epoxy coal asphalt anticorrosive paint is made of epoxy resin, coal tar asphalt, antirust pigments, additives and modified amines. The product has rapid drying, good adhesion, good flexibility, two-component packaging and convenient construction. It has the characteristics of acid resistance, alkali resistance, salt resistance, water resistance, oil resistance and so on.

The paint combines the characteristics of epoxy resin with high mechanical strength, large adhesion, chemical resistance and asphalt resistance, anti-microbial and anti-plant root system, and is a high-performance anti-corrosion insulating coating, which has good chemical resistance and water resistance.

It is suitable for the anti-corrosion of equipment and pipelines of oil, gas and water pipelines, tap water, gas, pipelines, oil refineries, chemical plants, sewage treatment plants, and can also be used as the anti-corrosion of the underwater part of offshore oil drilling platforms and ships, and the anti-corrosion of mines and underground facilities.

1): Before painting, the surface treatment of the base iron must be graded, and it is strictly forbidden to bring water, dust and oil into the construction to ensure the quality of painting.

2): The coating ratio is: component A (base material), component B (curing agent) = 20kg (20kg barrel): 1 kg of curing agent (or according to the proportion of the manufacturer).

3): The construction ratio method is: open the mouth of component A, add component B to component A, and stir it evenly. Allow for 30 minutes before painting.

4): This material is required to be used with the mixture, and the paint after the ratio must be used up within six hours. Unfinished materials should be sealed and stored.

5): The construction should be stopped on rainy days or when the relative humidity is greater than 75%. For parts with severe corrosive media, it is recommended to apply multiple coatings.

6): The product should be stored in a cool and dry place, and the construction site should avoid direct sunlight, isolate the fire source, and keep away from the heat source.

7): The effective storage period is 12 months.

This question is answered by the polyurea engineer of Yabu Machinery for you, and the difference between polyurea anticorrosion and epoxy coal pitch seems to be as follows:

Polyurea anti-corrosion is sprayed with polyurea spraying equipment, which is extremely hydrophobic, insensitive to environmental humidity, and can even be sprayed on water (or ice) to form a film, and can be constructed normally under extremely harsh environmental conditions, with particularly outstanding performance.

Epoxy coal asphalt is hand-painted.

Epoxy coal asphalt anticorrosive coating is a high-build type, and the coating film composed of epoxy resin, coal coke asphalt, pigments, additives and solvents has excellent adhesion, impact resistance and water resistance;

Excellent drying performance;

High anti-rust performance and good chemical and oil resistance, good wear resistance.
