DIRECTIONS FOR USE 1. Certain resins and hardeners are prone to crystallization. If crystallization does occur, warm the contents of the shipping container to 50 to 60C until allcrystals have dissolved. Shipping container must be loosely covered during the warming stage to prevent any pressure build- up . 2. Allow contents to cool to room temperature before continuing . 3. Complete cleaningof the substrates should be performed to remove contamination such as oxide layers, dust, moisture, salt and oils which can cause poor adhesion or corrosion ina bonded part . 4. Some separation of components is common during shipping and storage. For this reason, it is recommended that the contents of the shipping container be thoroughly mixed prior to use . 5. Power mixing is preferred to ensure a homogeneous product . 6.Accurately weigh resin and hardener into a cleancontainer inthe recommended ratio. Weighing apparatus having an accuracy in proportion to the amounts being weighed should be used . 7. Blendcomponents by hand, using a kneading motion, for 2 to 3 minutes . Scrape the bottom and sides of the mixing container frequently to produce a uniform mixture . 8. Ifpossible, power mix for an additional 2 to 3 minutes .Avoid high mixing speeds. This can entrap excessive amounts of air. It can also cause overheating of the mixture, resulting in reduced working life. 9. To ensure a void-free embedment, vacuum deairing or degassing should be performed to remove any entrapped air introduced during the mixing operation . 10. Vacuum deair mixture at 1 to 5mm mercury. The foam will rise several times the liquid height and then subside . 11. Continue vacuum deairing until most of the bubbling has ceased. This usually takes 3 to 10 minutes . 12. To facilitate deairing in difficult to deair materials, add 1 to 3 drops of an air release agent, such as ANTIFOAM 88 into 100 gram of mixture .
