Storage: Upon receipt of shipment, syringes should be unpacked immediately and stored in freezer at -10° C-20°C, 40°C, or -80C per recommendations on TDS.; Do not handle syringes from the body of the packaging. Handle from the ends of the packaging.; Store syringes vertically (upright) with tip side down. Do not store syringes horizontally (sideways).; Syringes should be stored in this manner until needed for production. Shelf life of syringes will be indicated on the products technical data sheet.; Syringes are labeled with product number, lot number, and manufacturing date. It is important that the syringes are used according to earliest manufacturing date, "FIFO" (first in, first out).
Shelf LIfe: 12 months at -40°C, 6 months at -20°C, max. 4 days at 25°C
Technology: Ready-to-Use Products
Safety and Handling: Use with adequate ventilation.; Keep away from sparks and open flames.; Avoid prolonged contact with skin and breathing of vapors.; Wash with soap and water to remove from skin.
Application Methods: Injection
Preparing Syringes For Use: To thaw syringes, remove them from the freezer taking care not to handle the body of the syringe (handle from the top and/or the tip) and allow them to acclimate to ambient temperature with the tip down.; Do not use hands to warm syringe.; The thawing time for each syringe will vary based on mass and composition but a minimum of 45 minutes for 3cc, 5cc, and 10cc and a minimum of 90 minutes for 30cc syringes should be observed.; Using a heat source to thaw syringes is not advised.; Proximity to a heat source during thawing should be greater than 3 feet.; Although most materials can be refrozen minimizing freeze-thaw cycles is recommended.; Once material is fully thawed remove protective wrapping.
Certifications and Compliance: ISO 14001
ISO 9001
Suggested Handling and Curing: Material is ready to use as received. Store frozen to maintain consistent flow properties. Allow material to warm up to room temperature before opening container. Prior to using, mix container well to re-suspend filler if packaged in containers. Cure for 60 minutes at 150°C, or for 30 minutes at 175°C.
Ready to Use Product Features: Anisotropic
Chemical Resistant
Excellent Coating Performance
Excellent Substrate Adhesion
Good Thermal Stability
