Epoxy resins
ORE-5020 is composed of ORE-5020(A) as basis and ORE-5020(B) as curing agent; its main components are epoxy resin, acid anhydride.ORE-5020 is specially designed for outdoor LED display and related product applications. It offers low mix viscosity, easy degas, durability at room temperature and fast cure at high or medium temperature. The cured product exhibits excellent mechanical strength and electrical properties and optical clarity. It is well suited to injection molding for LED.

Notes
1. | Since ORE-5020(A) and ORE-5020(B) will react slowly after mixed, and the viscosity of mixture will increase gradually. So, please be used in available time, avoiding the viscosity increased too high. |
2. | The viscosity of ORE-5020(A) will decrease by heat that is helpful to mix and degas. However, the available time will shorten if the temperature is too high. |
3. | ORE-5020(B) is acid anhydride that will absorb moisture in the air to form 1, 2-dicarboxylic acid precipitation. So, keep container closed immediately after use to avoid deterioration. |
4. | Curing conditions for reference only, For better curing properties should be extended curing time. For manufacture of larger products, should be curing at low temperatures for some time, and then rose to higher-temperature curing in order to avoid bending. |
5. | Avoid contact with skin or eyes. For skin contact, wash off with soap and water. For eye contact, flush with water first and then call a physician. |
