Acrylic resin is a commonly used synthetic resin, and its main components are acrylic monomers and acrylic copolymers. Acrylic resin has the characteristics of excellent transparency, weather resistance, chemical resistance, heat resistance and UV resistance. It also has the advantages of low cost and simple production process. It is widely used in coating, bonding, manufacturing and other processes in construction, automobile, electronics, printing, shoemaking and other industries. In addition, acrylic resins can also be used as important raw materials in the fields of inks, adhesives, and light-curing materials.

The results of these test items can help evaluate the quality and suitability of the acrylic resin and how it will perform in the actual application. Test methods and equipment vary according to specific acrylic resin types and test items.

Detection method

  1. Solid content: Use oven drying method, centrifugation method and other methods to test the solid content in the coating.

  2. Viscosity: Use an instrument such as a viscometer to measure the viscosity of the paint.

  3. Transparency: Test the transparency of the coating with light transmissIon Meter, light wavelength meter and other equipment.

  4. Chemical resistance: Use acidity meter, alkalinity meter, solvent immersion and other methods to test the acid and alkali resistance and solvent resistance of the coating.

  5. Hardness: Use pencil Hardness Tester, Rockwell Hardness Tester and other equipment to test the hardness of the coating.

  6. Density: Measure the density of the paint using an instrument such as a densitometer.

  7. Heat resistance: test the high temperature performance of the coating through oven high temperature test, constant temperature and humidity test and other methods.

  8. Weather resistance: test the UV resistance and corrosion resistance of the coating through artificial accelerated aging test or natural climate exposure.

  9. Adhesion: The degree of bonding between the coating and the substrate is tested by cross-hatch method, peeling method, tensile method and other methods.

  10. Others: According to the specific types of acrylic resins and testing items, select appropriate testing methods and equipment for testing, such as testing rheology, antistatic properties, antibacterial properties, etc.

*The performance test of acrylic resin needs to be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results.
