Solvent-free Epoxy Flooring

Solvent-free epoxy floor paint has high bonding strength with the base layer, low shrinkage when hardened, and is not easy to crack; the whole is seamless, easy to clean, dust-free, and bacteria-free; high solid content, and the thickness of the film is formed in one time; solvent-free, construction toxicity Low and in line with environmental protection requirements.

With the increasingly stringent environmental regulations and the maturity of solvent-free water-based epoxy floor coating application technology, solvent-based epoxy floor coatings are used less and less. Since the safety and environmental protection performance of solvent-based coatings is relatively low, harmful substances will evaporate from the coating during the construction process, endangering human health and the environment, and causing a waste of resources.

Solvent-free epoxy floor coating is more environmentally friendly than solvent-based epoxy floor paint. Because of its solvent-free characteristics, less construction toxicity and low VOC volatile content, it is an environmentally friendly product that meets the environmental protection requirements of today’s world.

Solvent-free epoxy floor paint has good safety performance. Because it does not contain flammable and volatile organic solvents, it is not flammable. It has strong resistance to penetration and chemical corrosion, and also has good tolerance for oil; it is not suitable for storage. , transportation and construction are safe and reliable.

Solvent-free epoxy floor coating has high solid content. It can form a thick film in one trowel application. It has high strength, high wear resistance and excellent pressure resistance. It can withstand long-term crushing by vehicles such as forklifts and forklifts.

Solvent-free epoxy floor paint has a wide range of applications, does not contain irritating flammable liquids, has no solvent volatilization during construction, and is odorless. It can also be constructed in small cabins and places with poor ventilation conditions, and will not be harmful to the health of construction workers. cause some damages.

Solvent-free Epoxy Vs Solvent Epoxy Floor Coating

Epoxy floor paint is a widely used floor coating material in industrial and commercial fields. Its performance differences directly affect the choice of usage scenarios. This article systematically analyzes the core differences between solvent-based and solvent-free epoxy floor paints from the dimensions of environmental protection, mechanical properties, safety and economy, and provides professional reference for project selection.

1. Significant difference in environmental performance

Solvent-based epoxy floor coating will continue to release VOC (volatile organic compounds) during the construction and curing stages. Actual measured data show that its VOC emissions can reach 200-400g/L. The volatilization of this type of organic solvent not only produces a pungent odor, but long-term contact may cause respiratory diseases in construction workers. Therefore, the specification requires that forced ventilation must be maintained during construction, and after completion, it must be left vacant for 3-5 days to allow the odor to dissipate.

The solvent-free product uses innovative formula technology to strictly control the VOC content below 10g/L, which complies with the GB/T 35602-2017 environmental protection standard. It can be safely constructed even in special scenarios such as closed cabins and medical clean rooms. Third-party testing shows that the TVOC release after curing is less than 0.05mg/m³, reaching the excellent indoor air quality standard.

2. Huge contrast in mechanical properties

The hardness of solvent-based floor coating is usually 2H-3H (pencil hardness), and the flexibility is 3mm shaft rod bending without cracks. In actual applications, stress cracks with a width of 3-5mm often appear in areas where forklifts frequently roll over for 6-12 months, and the local wear depth can reach 0.3mm/year.

Solvent-free products are optimized through toughening resin systems, and the hardness can reach 4H-6H, while the flexibility is improved to 1mm shaft rod bending without cracks. Laboratory accelerated wear tests show that the surface wear is less than 0.05mm after 5,000 round-trip rolling at a pressure of 1.5MPa. In actual cases, the forklift channel area remains intact and crack-free after 5 years of use in logistics warehouses.

3. Differentiation of safety risk levels

Although solvent-based epoxy coating products are not flammable as a whole (flash point > 60°C), the VOC concentration in the local space may reach 30%-50% of the lower explosion limit during construction, and explosion-proof electrical equipment must be configured. A case of a chemical plant shows that when construction is carried out in an unventilated environment, the concentration of benzene in the working area exceeds the limit by 8 times, resulting in acute poisoning of 3 workers.

Solvent-free epoxy coating products fundamentally eliminate the risk of combustion and explosion through water-based or 100% solid technology. In the transformation of the GMP workshop of the pharmaceutical factory, the combustible gas detector always shows zero value during construction, and construction is carried out without stopping production. Its chemical resistance is significantly improved, and it can withstand immersion in 10% sulfuric acid solution for 30 days without change.

When choosing, the key needs of the use scenario should be comprehensively considered: for non-key areas with short-term use and limited budget, solvent-based products are still cost-effective; in food and drug workshops, electronic clean rooms, logistics warehousing and other scenes with high requirements for environmental protection and durability, the full life cycle value advantage of solvent-free floor paint is significant. With stricter environmental regulations and technological advancement, solvent-free technology has become the mainstream development direction of the industry.
