Performance testing of light curing resins
A photocurable resin is a polymer material whose curing process is catalyzed by a photoinitiator under ultraviolet or visible light. Light curing resin is usually a single component material, นั่นคือ, it only needs to be coated on the substrate, through ultraviolet or visible light irradiation, can achieve rapid curing of the coating in a few seconds or minutes. Light curing resin has excellent heat resistance, ทนต่อสารเคมี, wear resistance and aging resistance, and has the advantages of low cost and easy to use, which is widely used in the coating and manufacturing process of 3D printing, อิเล็กทรอนิกส์, optics, printing and other fields.

The results of these test projects can help to evaluate the quality and suitability of the photocurable resin and how well it will perform in practical applications. The test method and equipment are different according to the specific type of light curing resin and the test item.
Performance testing of light curing resins
วิธีการตรวจจับ
Curing degree: Use microscope, infrared spectrometer and other equipment to test the curing degree of the coating.
ความหนืด: Use viscometer and other instruments to measure the viscosity of the paint.
ความแข็ง: Use Rockwell hardness tester, Babbitt hardness tester and other equipment to test the hardness of the coating.
ทนต่อการสึกหรอ: the wear resistance of the coating is tested by grinding wheel wear test and pencil hardness test.
ทนต่อสารเคมี: Use acidity meter, alkalinity meter, solvent immersion and other methods to test the acid and alkali resistance of the coating, solvent resistance, ฯลฯ.
Performance testing of light curing resins
Transparency: Test the transparency of the coating using equipment such as light transmitter and optical wavelength meter.
ความหนาแน่น: Measure the density of the paint using an instrument such as a densitometer.
Heat resistance: through oven high temperature test, constant temperature and humidity test and other methods to test the high temperature resistance of the coating.
Performance testing of light curing resins
Weather resistance: through artificial accelerated aging test or natural climate exposure test coating UV resistance, ความต้านทานการกัดกร่อน, ฯลฯ.
คนอื่น: according to the specific type of light curing resin and test items, select the appropriate test method and equipment for testing, such as testing antistatic, antibacterial, ฯลฯ.
