are applied above the sealing primer and below the finishing coat, which is a kind of intermediate coat, making the wood get further filling effect The finishing coat has three specifications, with slightly different components, different purposes and different characteristics Unsaturated polyester wood paint is a solventless paint, and the unsaturated polyester obtained by the condensation of binary acids and diols of unsaturated bonds is a film-forming substance Under the action of initiator, accelerator or special energy, it polymerizes and crosslinks with the unsaturated monomer containing free radicals used as diluent to form a network structure insoluble film The paint can be divided into three types by crosslinking curing: catalytic curing unsaturated polyester paint, light curing unsaturated polyester paint and electron beam unsaturated polyester paint The paint does not contain volatile solvents, does not emit toxic and harmful gases, does not pollute the environment, and can obtain a thick film through one-time coating; the paint film is polymerized by free radicals, dried at room temperature, carried out from the inside and outside of the paint film, and the thick film can also be solidified; the paint film has good fullness, hardness and high gloss Waterborne wood paint At present, the development types of Waterborne Wood Coatings in China are self crosslinking, acid curing and polyurethane water dispersing Compared with solvent coatings, waterborne wood coatings have incomparable advantages in energy saving and environmental protection There is not a large amount of VOC volatilized into the air, no organic solvent, water as diluent, which saves energy, but the disadvantages are also existing From the traditional point of view, in terms of film performance, compared with solvent based wood paint, the paint is slow in drying, low in hardness and easy to stick back, and the film fullness is less than that of solvent based wood
