Any coating that uses water as a solvent or as a dispersing medium can be called a water-based coating, or an environmentally friendly, clean-smelling, odorless film-forming additive. As the name suggests, water-based coatings should be more environmentally friendly. Water-based paint film-forming material is mainly water-soluble resin.
Oil-based paint, also known as grease paint, oil-based paint is mainly composed of four parts: film-forming substances, pigments, solvents, additives. The current film-forming material has been from the previous tung oil, linseed oil, catalpa oil and other inexpensive oils and fats into the excellent performance of the synthetic resin paint. Pigment is the colorful paint on the market. Solvent is a film-forming material will be dissolved or dispersed into a homogeneous liquid oil-based coatings, easy to construct into a film. Additives is an auxiliary component of the oil-based coatings. There are protection, decorative function but slow drying, coating film physical and chemical properties are poor.
Water-based paint is water-soluble paint, non-toxic and environmentally friendly, does not contain harmful solvents such as benzene, does not contain free TDI. Water-based paint is water as a diluent, 70-90% of its composition is water that is harmless to humans and the environment, does not contain benzene, halogenated hydrocarbons, and other toxic organic solvents and heavy metal compounds such as formaldehyde, lead, chromium and so on, and does not require curing agent, does not have a free TDI volatilization problem, so it is a safe and non-polluting environmentally friendly paint.
Secondly, water as a solvent has good flame retardant properties, non-flammable and non-explosive, easier for safe storage and transportation. The hardness of water-based paint reaches more than 2H, and the fullness is high, the film is fine and smooth, especially water-based wood paint.
Oil-based paint, also known as grease paint. Taking dry oil as the main film-forming substance, there are mainly varnish, thick paint, oil-based blending paint, oil-based antirust paint and putty, putty, etc. The oil used is mainly tung oil, linseed oil, catalpa oil, soybean oil, sunflower oil, fish oil and so on. The oils and fats used are mainly tung oil, linseed oil, catalpa oil, soybean oil, sunflower oil, fish oil, etc., which are characterized by easy production, low price, good brushability, film flexibility and good permeability.
The disadvantage of oil-based paint is that it contains strong irritating odor, the gas contains a large number of harmful substances, harming human health, generally 1-2 months after the use of strong irritating odor evaporates to basically tasteless, but a large number of harmful gases will still be slow-release volatilization 10-15 years.
In summary, although water-based paint also has disadvantages, but from the perspective of environmental protection, water-based paint is more environmentally friendly and healthy than oil-based paint.
Polyaspartic polyurea paint is 100% solid content paint, also known as solvent-free paint, is more environmentally friendly than water-based paint, is the best environmental grade paint. Feiyang has been specializing in polyaspartic polyurea for 30 years and can provide raw materials and formulations for coating manufacturers.
