- Application Instructions
- Surfaces must be clean, dry and free from grease, oil, paint, wax and weak oxide films and other surface contaminants. Chemical etching, sanding or grit blasting often gives the best results. Bring both components to room temperature prior to mixing. Just prior to using, blend the two components, Part A and Part B, in the ratio above. Mechanical mixing is preferable, but should be carried out at slow speeds (<300 rpm), taking as little air as possible into the adhesive batch. Spread a thin layer of the mixed adhesive on one or both of the parts to be bonded. Once the adhesive is applied, no open time is necessary. The surfaces can be assembled immediately. Parts should be assembled while the adhesive is still wet to the touch before it sets. The individual parts, the ambient temperature and the adhesive itself will dictate the open time permitted.

- Storage and Shelf Life Information
- Product should be stored in a cool dry place out of direct sunlight. Shelf life is based on proper product storage conditions and temperature. Exposure to elevated temperatures can reduce shelf life.
- Shelf Life Part A when stored 39°F or below is 6 months. Between 40°F and 80°F shelf life is 3 months.
- Shelf Life Part B: 12 months when stored up to 80°F.
- Note: Part B may be stored below 40°F with Part A without effecting shelf life.
