Types and characteristics of wood lacquers Nitro varnish A) Nitro varnish. Nitro varnish is a kind of transparent paint made from ***, alkyd resin, plasticizer and organic solvent. It is a kind of volatile paint, with quick drying and soft gloss. Nitro varnish is divided into light, semi-matt and matte. It can be used as needed. Nitro-lacquer also has its disadvantages: high wet weather is easy to whiten, low fullness, and low hardness. 1. Hand sweep paint. The nitrocellulose varnish is a kind of non-transparent paint made from ***, various synthetic resins, pigments and organic solvents. This paint is specially formulated for artificial construction and has a quick drying feature. 2. The main adjuvant of nitrocellulose lacquer is Tianna Water, which is a colorless, transparent liquid with a banana odor formed by mixing organic solvents such as esters, alcohols, benzene, and ketones. Mainly from the nitrocellulose lacquer and curing effect. White water, also known as anti-white water, is called ethylene glycol monobutyl ether. In the wet weather construction, the film will be whitish. The addition of nitromagnetized white water with a diluent amount of 10 to 15% can be eliminated.
Polyester paint B) Polyester paint. It is a thick paint made of polyester resin as the main film forming material. The paint film of the polyester paint is full and the layer is hard. Polyester paint also has a variety of varnish, called polyester varnish. Polyester paints need to be cured during the construction process. The amount of these curing agents accounts for one third of the total paint content. These hardeners are also known as hardeners and their main component is TDI (** diisocyanate/toluene diisocyanate). These TDIs that are in the free state will turn yellow, which will not only make the furniture painted yellow, but also make the neighboring walls yellow. This is a major drawback of polyester paint. At present, yellow-resistant polyester paint has appeared on the market, but it can only be resistant to yellow and cannot completely prevent yellowing. In addition, free TDI beyond the standard can also cause harm to humans. The harm of free TDI to the human body is mainly sensitization and stimulatory effects, including symptoms such as causing painful tearing, conjunctival hyperemia, coughing chest tightness, shortness of breath asthma, red papules, rash, contact atopic dermatitis and other symptoms. The international limit for free TDI is controlled below 0.5%.
Polyurethane paint C) Polyurethane paint Polyurethane paint Polyurethane paint that is polyester paint. Its film is tough, full gloss, strong adhesion, water resistance, abrasion resistance and corrosion resistance. It is widely used in advanced wood furniture and can also be used on metal surfaces. The disadvantages are mainly the problems of bubbling in contact with water and paint powder. As with polyester paint, it also has the problem of yellowing. The varnish variety of polyurethane paint is called polyurethane varnish.
UV wood paint D) UV wood paint UV wood paint that ultraviolet curing wood paint. It uses UV light curing and is the latest trending paint in the 21st century. The curing speed of the product is fast, generally 3-5 seconds to cure and dry. The product does not contain formaldehyde, benzene and TDI, truly green. Construction methods include: spraying, brushing, roller coating, shower coating, etc. Due to the chemical cross-link curing, the film performance is excellent, and due to the high solid content (usually >95%), the fullness is not comparable to other general paint types. Disadvantages: Professional equipment is required for curing.
Brief description of features 1. Phenolic paints are quick drying, high hardness, water resistance, abrasion resistance, but they are brittle and easy to yellow. 2. The lacquer is lacquer, which is fast drying, hard film, wear-resistant and clear wood grain, but the paint film is poor. 3. The alcohol ester paint is easy to construct, adheres firmly, and is bright and plump. It is often used in the finishing of outdoor wood products such as doors and windows, railings, and steel structures. However, its coating film is soft and has poor water resistance, so it should not be used on floors and desktops. 4. The advantages of unsaturated polyester paint are good fullness, fast drying speed, and it is suitable for industrialized assembly line production. 5. Polyurethane paints have excellent hardness, toughness and wear resistance, and are highly decorative but contain TDI. The nanometer wood lacquer applies the nanotechnology to the traditional wood coating industry and is currently one of the directions of global industrial efforts. Its technical difficulty is to ensure the stability of the product's molecular structure. With its strong R&D capability, the domestic brand Bossin Coatings successfully introduced Nazi technology into traditional wood lacquer and furniture lacquer coating manufacturing processes. 1) The nano wood lacquer is made of high-tech nano materials and hardeners. It has good leveling property and excellent construction and environmental protection. High solid content, high effective film-forming material, nano-wood lacquer 2) Large brushing area. 3) nano-wood primer with good filling, white primer strong hiding power; full white paint film, delicate texture, strong resistance to yellowing, tested; transparent varnish, translucent film, 4) especially nano-wood paint The degradation of decoration pollution, decomposition of benzene, aldehydes, VOCs and other harmful organic matter, air purification, and the sustainable release of air anion, the human body has health care features such as excellence and unique performance. 5) Baoshilong Nano Furniture Paint specializes in the special requirements of the furniture industry for paint products. It not only maintains the original special effects of nano-paint, but also has anti-microbial, anti-yellowing and paint film hardness resistance. Injury performance has greatly improved. It has been used in many landmark buildings and five-star hotels in China.
A type of resin paint used for wood products, including polyester, polyurethane paint, etc., can be divided into water and oil. According to the gloss can be divided into high light, semi-matte, matte. According to the use can be divided into furniture paint, floor paint and so on.
