1. Do not open the package before completely thawing.
2. Thaw to room temperature (25°C) before using. Any moisture present on the container after thawing should be removed before opening the container.
3. Seal any remaining material and store immediately at -40°C.
4. Once removed from original packaging, allow thawing syringes to equilibrate in tip-down orientation. Handle only the tip or flange. Do not handle syringes from the body.
5. Do not thaw material more than one time.
- Directions for Use
Selection of dispense equipment should be determined by application requirements - for advice on equipment selection and process optimization, users should contact HB Fuller technical support.
1. Ensure that air is not introduced to product during equipment set-up.
2. For best results, the substrate should be preheated to 80 to 100 °C. Ensure that the component and substrate have reached the prescribed temperature prior to dispensing the material. Measuring the substrate temperature adjacent to the component using a thermocouple is recommended.
3. The product can be dispensed using a pneumatic, auger or jet pump dispensing system.
4. Contact HB Fuller technical support for dispensing process recommendations.
- Clean-Up
Equipment, brushes, and spillage can be cleaned promptly after use with a mixture of anhydrous isopropyl alcohol and acetone that should be discarded after each use.
