• Product Characteristics
  • Optical Properties: It has high transparency, which can be used in occasions with high - transparency requirements, such as optical lenses and automotive lamp covers.
  • Weather Resistance: It has excellent light and weather resistance, and is not easy to fade or age due to natural factors such as ultraviolet rays, wind and rain. It is suitable for coatings and products used outdoors for a long time, such as architectural exterior wall coatings and outdoor billboards.
  • Chemical Stability: It has good water and chemical corrosion resistance, and can resist the erosion of a variety of chemical substances. It can be used to prepare anti - corrosion coatings to protect metal and other substrates from chemical media corrosion.
  • Mechanical Properties: Thermoplastic acrylic resin has a certain degree of flexibility and hardness after film - forming, and it dries quickly and is easy to construct. Thermosetting acrylic resin, after being made into coatings, has excellent fullness, gloss, hardness and solvent resistance.
• Classification and Characteristics
  • Thermoplastic Acrylic Resin: It does not undergo further cross - linking during the film - forming process, and has a relatively large molecular weight. It has good light and color retention properties. When preparing aluminum powder paint, the whiteness and positioning of aluminum powder are good. It is easy to construct, re - coat and rework. It is widely used in coatings for automobiles, electrical appliances, machinery, construction and other fields.
  • Thermosetting Acrylic Resin: There are certain functional groups in the structure. During paint - making, it reacts with the functional groups in the added amino resin and other substances to form a network structure, and the relative molecular weight is low. Thermosetting acrylic coatings have excellent fullness, gloss and hardness, and do not change color or turn yellow during high - temperature baking. They are often used in the baking paints of automobiles, motorcycles, bicycles and other products.
• Main Applications
  • Coating Field: It is an important film - forming substance of coatings, which can be used in architectural coatings, automotive coatings, industrial coatings, etc. It can provide good decorative and protective effects. For example, architectural exterior wall coatings can beautify the building appearance and protect the wall, and automotive coatings can make the vehicle body beautiful and prevent rust and corrosion.
  • Plastic Products: It is used to manufacture plastic products such as optical lenses, automotive lamp covers, instrument panels, TV casings, and refrigerator interiors. With its high transparency, impact resistance and good appearance effect, it can improve product quality and aesthetics.
  • Adhesives: It can be used as the main component of adhesives, with good adhesion, and can bond a variety of materials. It is widely used in packaging, leather, textile and other industries.
  • Other Fields: It can also be used in printing inks, textile pastes, medical materials and other fields. For example, in medical materials, it can be used to manufacture dental materials, bone cement, etc.
• Production Method: According to different production methods, it can be divided into emulsion polymerization products, suspension polymerization products, bulk polymerization and solution polymerization products. The main manufacturing raw materials include four categories: monomers, initiators, solvents and chain - transfer agents.
• Examples of Some Product Indicators
  • Thermosetting acrylic resin NX7831, with a solid content of (60±2)%, a viscosity of 4000 - 6000mpa.s/25℃, is characterized by high gloss and hardness, good constructability and high cost - performance, and is mainly used for general industrial baking paints.
  • Thermoplastic acrylic resin, with a solid content of (50±2)%, a viscosity of 3000 - 6000mpa.s/25℃, has excellent weather resistance, good leveling property and moderate drying property, and is suitable for container topcoats, marine paints, etc.
