Solvent and Solid Hydroxyl Acrylic Resins Crosslinkable – with Polyisocyanates

Application:

The main use of resin with high solid percentage is in the formulation of paints that require less solvent. This issue is very important due to the strict regulations limiting the volatile components of VOC chemical products in Europe. Reducing the consumption of volatile solvents, especially in the dilution stage before application, is one of the main ways to adjust the formulation to meet environmental standards. In order to reduce the consumption of paint thinner and solvent, a formulation is necessary that, despite having a sufficient amount of resin in the formulation, the paint can be brought to the target viscosity with less solvent.

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.

Technical Specifications:

With common polyol products to increase the share of resin (solid percentage) of the paint, the hydrogen bonds are increased and the viscosity is greatly increased due to the approach of the hydroxyl groups (especially in polyols with high OH percentage). Therefore, producing polyol resin with high hydroxyl percentage and low viscosity is the solution to this problem. The main challenge in the production of these products, compared to the usual resin with a similar composition of monomers, is to reduce the viscosity while providing the hydroxyl functional group and reactivity within the required range. The results of FTIR, GPC and DSC tests have been obtained.

Advantages:

The possibility of customization by changing the monomer and hydroxyl percentage
