Storage & Handling

Storage Conditions

Product should be stored in a cool dry place out of direct sunlight. The shelf life is from date of manufacture. Shelf life is based on the products being stored properly at temperatures between 12°C and 25°C. Exposure to temperatures above 25°C will reduce the shelf life. This product should not be frozen.

Shelf Life

12 months (unopened)

Technical Details & Test Data

General 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. Be sure to stir the entire container of EY2562A. It contains hollow glass spheres which rise to the surface of the liquid resin. The contents must be of uniform consistency before adding hardener. Just prior to using, blend the two components, Part A and Part B, in the ratio above. Stir thoroughly with a slow speed mixer, to avoid breaking the glass microballoons. 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.
