Comparison of the advantages and disadvantages of single-group, two-part, water-based UV.

The advantages of single-pack water-like wood paint
with the progress of water-like wood paint technology, the performance of single-group water-like paint is getting better and better. For example, paint film flexibility, transparency, drying fast, good adhesion, paint film delicate soft and beautiful, at the same time in the paint film plumpness, water resistance, hardness and scratch resistance on the above also have a significant improvement, can fully meet the cabinet, wall panels, bookshelves, display cabinets, beds and other facade system furniture coating needs.
the current single-pack water-based wood paint in pine children's furniture and outdoor paint application is very mature, has accounted for more than half of the market share

. At present, water-resistant paint has breathable, breathable and impermeable, stretch, high toughness, long-lasting weather resistance and other oily paint does not have the characteristics, can protect wood doors and windows for a longer period of time to deal with the test of the dual environment inside and outside the home, and its coating process and effects are gradually in line with the needs of wooden doors and windows, and now solid wooden windows and aluminum windows water-esque coating also ushered in a high-speed development period.
The shortage of single-component water-based wood paint
water-based paint with water as a thinner, in the process of use will change the moisture content of wood, wood moisture content changes will lead to wood swelling, bending deformation, thus increasing the difficulty of water-based paint construction. In addition, water-resistant paint is suitable for thinner, to make open effect and semi-closed effect, so in the processing and grinding to be more fine, which requires furniture enterprises have a higher level of production technology.
Because the single-part water-like paint depends on the natural volatile film of moisture, so the construction temperature, humidity has certain requirements, and the paint film is slow to do, cross-linking degree is not high, the formation of the paint film is not dense enough, the quality of the final film is not good to ensure, so the hardness of the single-part water-resistant paint paint and anti-scratch, resistance is not high, closed effect is not strong. Therefore, a single component of water-like paint is not suitable for coating furniture with high hardness requirements, such as tables, floors and other flat system coating, and oily pine, etc. is difficult to close the oil floating.
As far as the whole furniture industry is concerned, the quality of single-pack water-based paint is uneven, the effect will be very different, some poor quality low-grade water-based paint products affect the market's correct understanding and development of water-based paint, but single-group water-based paint as the main body of water-based paint, from raw materials to construction applications will be rapid development, to meet the needs of coating to get a wider range of applications.
two-part water-based wood paint than the common single-part water-based wood paint has a better comprehensive performance, because in a single-group water-based paint on the basis of the addition of curing agent to assist in film formation, so that the film polymer chemical reaction, the formation of a network structure, and eventually form a paint film, rather than relying on the natural volatile physical film of moisture, thereby greatly improving the performance of the paint film.
The advantages of two-group water-based wood paint
Because it is a chemical reaction into a film, so the comprehensive performance of the paint film has been significantly improved, especially water resistance, resistance, stain resistance, anti-adhesion, hardness resistance scratch, iron resistance, wear resistance and other performance is more prominent. Paint film hardness can reach 2H, performance can be comparable with traditional PU oily paint, can be applied in the flat system of furniture coating, to meet the needs of hardness and scratch resistance, and can also be used as a closed primer and single-component water-based wood paint, effectively closed wood grease, tingate and so on.
The disadvantages of two-part water-like wood paint
Although the two-part water-like paint relies on curing agent to increase the performance of water-like paint film, but the environmental protection of water-like paint has a certain impact, although water-like paint curing agent also does not contain formaldehyde, benzene and other substances, but also increase some VOC emissions and odors. At the same time, the cost of coating two-pack water-like wood paint is more than double that of single-pack water-like wood paint. For furniture enterprises, although the two-part water-like paint environmental protection and performance can also meet the requirements of furniture coating, but the increase in coating costs, relatively easy for furniture enterprises to accept.
Of course, the cost of coating can be effectively controlled, Qumei furniture all furniture using water-based coating, for this situation of Burtink water-based paint, it is equipped with two sets of water-based paint, and it is reported that Qumei furniture coating costs increased by only about 30%, combined with the enterprise water-based coating application of the comprehensive cost than oily paint is not much higher. Burtinck water-based paint for Qumei furniture with the coating process, fully consider the problem of coating costs and the reasonable mix of the process, it can be said that not only to meet the needs of coating, but also to effectively control the cost of coating.
UV paint, that is, UV-cured water-like wood paint, light trigger through ultraviolet light exposure to promote cross-linking reaction, and eventually form a paint film. Water-based UV paint combines the advantages of traditional water-based coatings with UV-cured coatings. Although in most cases a small amount of additives is still required to cause VOC problems, voC content is significantly reduced compared to photo-curing coatings that use active thinners.
advantages of water-based UV paint
the prepared water-based UV has excellent wear resistance, better than water-based 2KPU, solvent-based PU and 100% UV series, in office furniture has a strong competitiveness.
addition to the above advantages, there is also a very prominent advantage is to solve the contradiction between the hardness and flexibility of traditional photo-cured coatings, which is very important for many applications. It is well known that coatings with excellent performance often require high hardness and flexibility. High hardness allows the paint film to resist mechanical forces or chemicals, while high flexibility adapts to the expansion or contraction of substrates such as wood, metals, etc. due to changes in humidity or temperature, as well as the deformation of soft substrates. From the analysis of the relationship between molecular structure and performance, only substances with high relative molecular mass can have high hardness and flexibility.
Water-based UV paint shortcomings
water-based UV paint there is water, so compared to oily UV paint, before light curing, need to dry dewatering, in the photo-curing equipment needs to add flash steaming equipment, and the high evaporation heat of water leads to increased energy consumption, but also make the production time longer. And light curing coating is only suitable for simple structure of flat coating, special-shaped structure ultraviolet radiation can not be irradiated so can not do.
