What are the significant advantages of solvent-free epoxy topcoat over traditional solvent-based epoxy topcoat?
Release Time : 2024-08-20
Solvent-free epoxy topcoat shows significant advantages in many aspects compared to traditional solvent-based epoxy topcoat.
Environmental protection
Solvent-free epoxy topcoat: does not contain volatile organic compounds (VOC), so no harmful volatile gases will be generated during the construction process, no pollution to the environment, and in line with the current concept of green environmental protection.
Traditional solvent-based epoxy topcoat: contains high VOC, which will release harmful gases during construction, posing a potential threat to the environment and the health of construction workers.
Safety
Solvent-free epoxy topcoat: Since it does not contain flammable organic solvents, it is not a flammable item, and it is safer during storage, transportation and construction, reducing the risk of fire.
Traditional solvent-based epoxy topcoat: contains flammable organic solvents, there are hidden dangers of combustion and explosion, posing a threat to the safety of construction workers.
Construction performance
Solvent-free epoxy topcoat: no solvent volatilization during construction, so the construction environment has low requirements for ventilation, and can be used in small cabins and places with poor ventilation conditions. At the same time, it has good self-leveling properties, a large film thickness in one time, and a smooth and bright surface.
Traditional solvent-based epoxy topcoat: Good ventilation is required during construction to reduce the harm of harmful substances produced by solvent volatilization to construction workers. Its construction method may be relatively complicated and requires multiple processes to achieve the ideal coating effect.
Physical properties
Solvent-free epoxy topcoat: Good flexibility, can withstand the pressure of large machinery and equipment or heavy objects without easy delamination or breakage; strong hardness, scratch resistance, not easy to be scratched by objects, thus increasing the service life. In addition, it has strong hiding power, can form a thick coating film, and has good surface gloss.
Traditional solvent-based epoxy topcoat: Although it also has certain flexibility and hardness, it may be slightly inferior to solvent-free epoxy topcoat. Its hiding power may not be as strong as solvent-free epoxy topcoat, and more construction passes are required to achieve the ideal coating effect.
Economic efficiency
Solvent-free epoxy topcoat: Although the unit price may be slightly higher than that of traditional solvent-based epoxy topcoat, due to its high solid content (nearly 100%), less paint is required to achieve the same coating thickness. At the same time, since it can achieve high film thickness in one coat, the number of construction coats can be reduced, thereby reducing the cost of coating construction.
Traditional solvent-based epoxy topcoat: Because it contains solvents, its solid content is relatively low, so more paint may be required to achieve the same coating thickness. At the same time, since the number of construction coats may be large, the cost of coating construction is also increased.
Solvent-free epoxy topcoat has shown significant advantages in environmental protection, safety, construction performance, physical properties and economy. These advantages have enabled solvent-free epoxy topcoat to be applied and promoted in more and more fields.
