Water-based wood lacquer is accepted by consumers because of its non-toxic, environmentally friendly, odorless, volatile, non-flammable, non-explosive, high-safety, non-yellowing, and large brushing area.
It is precisely because of this, major paint manufacturers have launched water-based wood lacquer products, how to know, understand, and purchase become a top priority for consumers.
Despite the large number of brands, we can be divided into four categories based on their main components:
The first category: waterborne wood lacquer based on acrylic acid
Its main feature is good adhesion, does not deepen the color of wood, but wear and chemical resistance is poor, the hardness of the paint film is soft, the pencil rule is HB, the fullness is poor, the comprehensive performance is general, the construction is prone to defects. . Because of its low cost and low technical content, it is the main product that most waterborne wood lacquer enterprises bring to the market, and its advantage is that it is cheap.
The second category: waterborne wood lacquer based on the combination of acrylic acid and polyurethane
In addition to adhering to the characteristics of acrylic paint, it also features wear resistance and chemical resistance. Some companies are labeled as water-based polyester paint. The hardness of the paint film is good, the pencil rule is 1H, the fullness is good, and the comprehensive performance is close to the oil paint.
The third category: waterborne wood lacquer based on polyurethane
Its comprehensive performance is superior, the fullness is high, the hardness of the paint film can reach 1.5-2H, the wear resistance even exceeds the oil paint, and the service life and color matching have obvious advantages. It is a high-grade product in water-based wood lacquer, suitable for high-grade solid wood furniture. . Sanqing paint is one of the few manufacturers that can produce water-based two-component paint, and the water-based wood paint products are complete and easy to use.
The fourth category: pseudo waterborne wood lacquer
Pseudo-aqueous paints should also be added with chemicals, such as "hardener", "paint film enhancer", "special dilution water", etc. Some can also be diluted with water, but the solvent content is high, which is more harmful to the human body. Some even exceed the toxicity of oil paints, and some companies are labeled as water-based polyester paints.
Understand the classification of waterborne wood lacquer, consumers can choose according to their own needs, if the price is cheap, just choose the first type of waterborne wood lacquer; if it is more than mid-range, more elaborate decoration, it is best to use Class II or Class 3 waterborne wood lacquer. Let's tell you four ways to identify waterborne wood lacquer.
Method 1: Smell
When consumers choose environmentally friendly paints, they may first smell them with their noses and smell the pungent smell of the paint. Acrylic acid has a slightly sour taste, while polyurethane has a slight oily fragrance.
Method 2: Professional testing
Consumers can bring a professional formaldehyde test kit or tester to test on site, so that the purchase is foolproof. The national VOC content standard for coatings should not exceed 200 grams per liter, the preferred coating is less than 100 grams per liter, and the environmentally friendly coating is close to zero.
Method 3: Environmental certification
The national standard for environmentally friendly coatings is the ten-ring mark. The packaging of health and environmental protection products is certified by China's environmental protection products. Consumers must recognize the green ten-circle environmental protection mark on the packaging. At the same time, the consumer can request a third-party test certificate from the merchant.
Method four: packaging
When choosing environmentally friendly coatings, we must first look at the packaging, packaging and promotional materials to be meticulous, which proves that the management of the company is strict. If the packaging and data are incomplete, the data is unclear, and there are even low-level errors such as typos, such paints must be carefully selected.
