Hydroxyl Acrylic Resin

Application:

The desired resin is used as a polyol agent in polyurethane coatings. These polyurethane coatings are used in automotive or protective coatings due to the high mechanical properties caused by this polyol.

Product Introduction:

Polyurethanes are one of the most important industrial coatings, ranging from relatively simple glaze-like coatings to high-quality automobile coatings. These coatings are usually the result of the reaction of an alcohol (R-OH) and an isocyanate (R-NCO), and the most common type of urethane coating is a solvent-based and two-part coating, where one component contains polyisocyanate and the other polyol. The most common types of polyol are acrylic polyol, polyester polyol and polyether polyols. Owing to their linear structure, acrylic polyol polyurethane resins have high light resistance, good moisture resistance, and excellent hardness, and are widely used in protective coatings. This material is used as a polyol in combination with isocyanates to produce a variety of polyurethane coatings.

This product has the ability to form crosslinks with polyisocyanates with a hydroxyl percentage of less than 3%.

Technical Specifications:

Acrylic resin is a resin composed of acrylic acid derivatives (CH2 = CH – OOH). The molecular weight of acrylic resins used in urethane coatings is usually low (example: 25000 daltons) and the molecular weight of the final cross-linking film is quite high (example: infinity). The low molecular weight of acrylic resin makes it possible to make a coating with a high solid percentage and medium to low viscosity. Acrylic polyols, like most acrylic resins, are prepared by radical polymerization. Any acrylate monomer containing hydroxyl groups such as hydroxyethyl methacrylate, hydroxybutyl acrylate and hydroxyethyl acrylate can exist in the polymer structure. However, only hydroxylated monomers are not used in the polymer structure and other acrylate monomers are also used.

Advantages:

* High volume production

* Low prices
