Lb-508 is a one component UV curable acrylate adhesive. The product is designed for the adhesion of PMMA, PC, pet and other general plastics. It is mainly used for projects with glue overflow and need surface drying. It has the characteristics of moderate viscosity, strong adhesion, fast surface drying, high transparency, good weather resistance and so on. The plastic adhesive glass also has certain adhesion.

Curing conditions
The curing rate and depth of lb-508 depend on the light intensity, the spectral distribution of the light source, the irradiation time and the light transmittance of the bonded material. The following data are measured under the condition of 20 MW / cm2 UV radiation generated by high pressure mercury lamp (more than 400 W UV lamp is recommended)

Weatherability test
The following data were obtained after curing with accumulated energy of 600 MJ / cm2 of high pressure mercury lamp source
Base material test condition bond strength retention rate (%)
PC / Pet - 25 ℃ (1H) + 55 ℃ (1H) 20 cycles + 90 Cycles
PET / glass - 25 ℃ (1H) + 55 ℃ (1H) 20 + 90 Cycles
PC/PET 65℃90%RH(72h) 92
PET/GLASS 65℃90%RH(72h) 92
Storage conditions
Please store it in a cool and dark place. Please cover the bottle after opening the cap. Do not pour the glue back to the original bottle before using it. The best storage temperature is 8-28 ℃, too high or too low will affect the performance of the glue, and the shelf life is 8 months.
explain
The above data are measured by lebei technicians in the laboratory for customers' reference. However, due to the different methods and conditions of each customer, it is suggested that customers find out the best process and method according to their own conditions, and the measured data shall prevail.
