01 polyacrylate coating finishing agent

Polyacrylate coating agent is one of the most commonly used coating agents. It is generally made up of hard components (such as methyl acrylate) and soft components (such as butyl acrylate). Its advantages are: light fastness and climate fastness, no easy yellowing; good compatibility, conducive features to non-ferrous coating products; good washing resistance, strong adhesion, low cost. Its shortcomings are: poor elasticity, easy wrinkle, poor surface finish, and it is difficult to adjust the moderate feel.

Solvent-based acrylate coating agent has high viscosity and thixotropy, suitable for soft thin fabric coating finishing. When combined with waterproof agent, water repellent and waterproof finishing effect can be obtained. The solvents used in this kind of coating agent are generally toluene or ethyl acetate, which are flammable and explosive substances. It is easy to pollute the environment and bring unsafe factors when using.

02 polyurethane coating finishing agent

Polyurethane, known as polyurethane, is a macromolecule compound with NHCOO unit in its molecular structure, which is formed by copolymerization of isocyanate with compounds with more than two hydroxyl groups. According to its composition, it can be divided into polyester type, polyether type, aromatic isocyanate type and aliphatic isocyanate type. According to the medium used, it can be divided into two types: solvent type and water system type.

Polyurethane coating agent is the main type of coating agent developed in recent years. Its advantages are: soft and elastic film formation; good film strength, which can be used for very thin coating products; porous coating, which makes the coating products have moisture permeability and air permeability; film wear resistance, water resistance, dry cleaning resistance. Its shortcomings are: high cost; poor weather resistance; chemical resistance (such as alkali), poor heat resistance.
