The waterborne industrial coatings market has made great progress through cultivation in the past ten years, especially in recent years, driven by national environmental protection policies. It has achieved large-scale application in containers, auto parts, rail transit and other market segments. It has also achieved good applications in the automotive, wood and other market segments, and the future potential of these two markets is still great. In the specific subdivisions of the equipment and steel structure industries, different degrees of progress have been made according to the respective characteristics of the industry, and they are in different stages of development. According to the characteristics of waterborne coatings, the characteristics of application targets, considering the promotion of corresponding laws and regulations and customer wishes, waterborne coatings will achieve rapid development in their suitable markets. First of all, the advantages of waterborne coatings and the technological advancement of waterborne coatings will promote the steady growth of the waterborne coatings market.
Water-based industrial paint is welcomed by users because of its energy saving, environmental protection, will not cause harm and pollution to the human body and the environment, and some places and industrial parks even clearly require that settled enterprises must use water-based paint to pass the environmental impact assessment and cleaner production audit. Therefore, the application of coatings in the industrial field has changed to water-based industrial paint. Waterborne industrial paint is the direction of the future development of the coating industry, and it is also an alternative product to oil-based paint.
First, the difference between waterborne industrial paint and ordinary water-based paint in the resin system:
Ordinary water paint is made of styrene propylene and pure propylene emulsion resin system, most of which are single components.
Waterborne industrial paints were originally made of the above resin systems, but because their performance was not as good as solvent-based coatings, users did not recognize them. At present, the resin system of a new generation of waterborne industrial paint includes waterborne alkyd, waterborne epoxy, waterborne epoxy, waterborne acrylic polyurethane and different modified and flattened resin systems, which have completely surpassed solventborne coatings in performance.
Second, the difference between waterborne industrial paint and ordinary water paint in terms of performance characteristics:
In the publicity of ordinary water paint, it often highlights the concepts of clean odor and environmental protection, as well as more practical scrub resistance and other properties.
Industrial water paint, because of its use restrictions, often requires higher performance. For example, salt spray resistance, impact resistance, adhesion and other indicators are much higher than ordinary water paint.
1. Difference between product components:
Water paint is made of water-based resin, water as diluent, EU ROHS environmental protection standard pigment filler.
The paint is made of synthetic resin, benzene organic solvent, TDI, pigment filler.
2. Security difference:
Water paint has no hidden danger of combustion and explosion in the whole process of storage, transportation and application. Paint has a hidden danger of combustion and explosion in the whole process of storage, transportation and application.
3. Difference between gas and liquid emission pollution:
The water paint gas is discharged as non-polluting water vapor gas, and the liquid discharge is a harmless aqueous solution, which does not need to be treated and the discharge meets the standard.
Paint gas emission is highly polluting organic gas, liquid discharge is highly polluting organic solution, and the discharge without treatment is not up to standard.
4. Difference between ambient air pollution in product applications:
There is no irritating odor when the water paint is applied, and the application environment does not produce environmental pollution. Paint application produces a difficult pungent odor and causes serious pollution to the environment.
5. Difference between finished product pollutant residues:
The finished product coated with water paint has no residue of pollutants and no residue of irritating odor.
Finished products coated with paint have residues of pollutants and serious residues of irritating odors.
6. The difference between the user's dilution cost and the cleaning of painting appliances:
The water paint is diluted with tap water, and the dilution cost is extremely low; Cleaning with tap water has almost no cost consumption. The paint is diluted with organic solvents, and the dilution cost is high; Cleaning with organic solvents, the cost of consumption is higher.
7. Difference between user safety and environmental protection social value:
The water paint does not burn or explode, completely eradicating the tragedy of "decades of hard work, one fire is all finished"; It does not have social impact and meets the requirements of the national 13th Five-Year Plan "green water and green mountains" development policy. Paint is flammable and explosive, it is impossible to prevent, "tens of millions" input, difficult to prevent "in case"; Produce a large number of volatile harmful substances, poison themselves and pollute others.
