Selection of Resin for Waterborne Wood Coatings in Different Fields

The classification and characteristics of several resins were briefly discussed last time
the classification and characteristics of several water-based resins

Water-based wood paint applications generally have the following:
furniture, interior decoration, outdoor, children's toys, flooring,
etc.; In addition to meeting national standards, there will be higher requirements for certain performance

.
furniture
furniture is the main application area of wood coatings, mainly in factory production applications, the overall performance requirements are higher, is the main competitive field of high-grade wood coatings production plant.
in the construction, decorative and protective requirements, in the selection of water-based resins, focus on the following properties of the resin:
construction: drying speed, polishing, anti-adhesion
drecording: anti-rise ribs, transparency, Feel, plumpness, perforation
protection: hardness, scratch resistance, water resistance, resistance, iron resistance, adhesion, impact resistance
In addition to the above performance, the use of the cabinet will have higher requirements in terms of odor.
different functional uses of furniture, the performance requirements are not the same. General performance requirements of furniture paint can choose water-based acrylic resin or water-based polyurethane resin, performance has higher requirements, such as water resistance, hardness, iron resistance, odor and other requirements, optional

system hydroxypropyl acrylic resin.
Interior decoration
interior decoration wood coating is based on the field application-based paint type, brush coating-based, in the market sales occupy a certain proportion, the overall performance requirements will not be too high.
Relatively speaking, its construction requirements are higher, mainly the can opening effect, anti-flow hanging, anti-brush marks, mainly through the fluidizer adjustment
Of course, in the decorative and protective also to meet the basic requirements of the user.
in the choice of resins, generally water-based acrylic resin-based, cost-effective, but also can choose water-based polyurethane or water-based acrylic modified polyurethane to achieve better paint film effect.
outdoor
wood coating is for outdoor gazebos, lounge chairs, bridges, fences and other types of outdoor wood applications. Brushing or scrubbing is the main focus, with a greater focus on protection in terms of resin performance requirements.
such as water resistance, weather resistance, yellowing resistance, aging resistance, flexibility, impact resistance, adhesion and so on.
in the choice of resin, generally choose a lower
MFFT
water-based acrylic resin (pure propylene).
Children's Toys
Children's toys with wood coating for wood toys, mainly factory construction, to spray, immersion and other coating methods, in the resin performance requirements, more important to decorative.
environmental requirements, heavy metals,
VOC
are also extremely strict requirements. Mostly for the selection of water-based acrylic resin and water-based polyurethane resin for single-part use.
flooring
flooring wood paint is mainly factory construction, due to the hardness, wear resistance, water resistance and other performance of the very high requirements, the general coating is difficult to meet the requirements. Mostly photo-cured coatings (
UV
), mainly for shower coating, rolling coating. Special water-based photo-curing resins (UV-specific

resins)
be used.
