5. Notes
1) ORE-5010A and ORE-5010B 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-5010A 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 -5010B 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 temperature for some time, and then rose to higher-temperature curing in order to avoid bending.
5).Avoid contacting with skin and eyes. For skin contact; wash off with soap and water. For eye contact, flush with water first and then call a physician.
