- Instructions
- Bring both components to room temperature prior to mixing.
- Cartridge format: Mixer should be attached keeping the cartridge vertical and any air pocket purged this way. After the mixer contains material, the mixer tip can be dropped to dispense pre-bleed amount. Attach a new static mixer with each cartridge, then pre-bleed the first 3 inches of dispensed material or until a uniform color is obtained. Maintain adequate velocity during dispensing to ensure complete mixing.
- Bulk format: weigh and mix parts A and B accurately and thoroughly, scraping sides of container often. Do not pour from mixing container, transfer to a new container as residual unmixed material may cause a tacky spot on the surface of the casting. Maintain adequate velocity during dispensing to ensure complete mixing.
- Allow to cure undisturbed until product is fully gelled or tack-free to the touch.
- Clean up uncured resin with suitable organic solvent such as MEK, acetone or other organic solvent.

Storage & Handling
- Shelf Life And Storage
- 6 months at 25 °C Bulk.
- 12 months at 25 °C in cartridges that are foil bagged and desiccant packed.
- Isocyanates are sensitive to moisture and should be kept in their original container or in a volume tank under dry nitrogen blanketing. Many isocyanates are prone to dimerization, the formation of a white precipitate. Products with minor amounts of this precipitate normally cure to full properties. Storage at 20 – 30 °C (68 °F to 86 °F) is recommended to ensure full shelf life.
