STORAGE:

Store material in a contaminate free container and store at O degrees F for extended storage. For shorter storage time requirements store at 40 degrees F, this enables quicker stabilization times.

APPLICATION:

Remove material from cold storage at least 20 hours prior to use to allow for stabilization at room temperature. Keep the material containerized to prevent moisture from condensing on the material. Weigh out only enough part A into a clean, dry container to be used within the working life of the adhesive. Add the appropriate amount of part B. Mix well to a uniform consistency and color, about 1 to 2 minutes, scraping the sides of the container. Apply to clean, dry substrate with spatula or roller or putty knife. Join the parts to be bonded and apply sufficient pressure to squeeze out some adhesive( approx. 5 psi) Cure per one of the recommended cure cycles.

CLEAN UP:

The adhesive can be removed from non-bonding areas with ketones or methylene chloride. Be sure to follow all Material Safety Data Sheet (MSDS) guidelines for the solvent to be used.

CAUTION:

This material contains epoxy resins and amines which may cause irritation to sensitive skin. Avoid contact with eyes or skin. If contact with skin occurs, wash as soon as possible with soap and water. If contact with eyes occurs, flush with water for 15 minutes. Do not handle or use this material until Material Safety Data Sheet has been read and understood. The user of this material is required to use the necessary protective equipment as directed by applicable state and federal laws when handling, curing, and grinding this material.
