What is the connection and difference between varnish, paint and water-based paint?

Paint: coated on the surface of the object can form a protective, decorative or special properties (such as insulation, anticorrosion, marking, etc.) of the solid film of a class of liquid or solid materials. Including oil (sex) paint, water-based paint, powder coatings. Powder coating, is used for electrostatic spraying: and through the electrostatic gun spraying in iron, aluminum product surface after high-temperature curing of a process, this surface treatment process to better protect the product surface, so that it is beautiful, bright color, corrosion resistance is more.

Difference between water-based paint and oil-based paint:

Comparison of water-based paint and oil-based paint

One, environmental protection and health comparisons, waterborne polyester paint (waterborne paint) has an absolute advantage

(1) Toxicity: As waterborne polyester paint (waterborne paint) is the use of advanced polyurethane system, ultra-low VOC content (lower than the national mandatory standard of 200mg/L), is truly non-toxic. standard), is truly non-toxic and odorless high-tech environmental protection products. While nitro paint and polyester paint (oil-based paint) add organic solvents, their products contain benzene, toluene, xylene and its derivatives, so the toxicity of polyester paint is the highest, while the toxicity of nitro paint is second.

(2) flammability: water-based wood varnish using water instead of organic solvents, its products have the characteristics of safe and non-flammable. Greatly reduce the production and distribution of dangerous factors and trouble. And nitro paint and polyester paint (oil-based paint) containing benzene, xylene, acetone, solvent gasoline, Tena water are highly flammable items.

(3) irritating odor: water-based wood paint uses water instead of organic solvents, its products in the painting, will not produce any irritating odor. And nitro lacquer and polyester lacquer containing organic solvents, will be in the process of painting and drying volatile into the air, directly stimulate the human sensory organs

(4) paint after moving in time: waterborne wood lacquer has fewer brush strokes, fast-drying, easy to paint, there is no time limit after the matching of the paint, after painting can be moved in. And nitro paint and polyester paint because of its organic solvents will be in the drying process volatile harmful gases, so the use of nitro paint and polyester paint (oil paint) decoration of the house, generally can not be painted directly after moving in, need to wait for a period of isolation time.

Two, quality and performance comparisons, the overall performance is equal

(1) hardness: water-based polyester paint due to the use of advanced water-based polyurethane system, in the case of the film is completely dry, you can achieve the physical indicators of the 2H; ordinary polyurethane paint as a result of the use of added organic curing agent, so the use of ordinary polyester paint film hardness is the highest; and nitrocellulose lacquers (oily paints) The need for up to more than ten times the brush, the hardness of its paint film is the worst!

(2) feel, fullness: polyester paint in the film feel, fullness of the effect is the best, water-based polyester paint using a thin coating + "virtual texture" of the technology, after painting the feel and fullness of a great improvement; and nitrocellulose lacquer film feel, fullness is not very good.

(3) wear-resistant, yellowing-resistant, durable: water-based polyester paint (water-based paint) using advanced aliphatic polyurethane system, the film surface is hard, wear-resistant, flexible film, will not be whitened due to the collision; not yellowing, the film stays clear and transparent over the years; resistance to artificial aging of 800 hours, the long outdoor durability. And nitro paint and polyester paint (oil-based paint) exists easy to collision white, easy to yellow, can not maintain the effect of the shortcomings of the long-lasting.

Three, construction and cost comparison, basically the same

(1) easy to construct degree: water-based polyester paint with water dilution, without the need to add thinner, easy to use direct construction; while nitro and polyester paints need to add thinner or curing agent, and must be in accordance with a fixed ratio, so the nitro and polyester paints in the construction process, the need for professional guidance.

(2) paint waste, painting number of times: water-based polyester paint in the use of finished, for the remaining paint, can be stored in a cool place to continue to save; and nitro and polyester paints due to the addition of a curing agent, so can only be used in a one-time use, for the rest of the paint will cause waste. In the number of times of painting, water-based polyester paint four times that can achieve the effect of nitro paint ten times.

(3) can be repaired: the use of water-based polyester paint painted wood furniture, can be directly covered in the repair painted on; and the use of nitro lacquer, polyurethane lacquer wood furniture, in the repair, you must first use sandpaper to sand off the old paint film, can be painted on.

(4) film fee, cost: the use of water-based polyester paint per square meter requires less paint, generally once in 30M2/Kg or so, while not having to add Tianna water dilution, less time. So the cost of using water-based wood paint is basically the same as the use of nitro paint and polyester paint.
