Fastweld 10 A/B epoxy adhesive is a rapid-setting, two-component paste offering a convenient one-to-one mixing ratio by volume or weight. Fastweld 10 A/B epoxy adhesive produces strong bonds in a very short period. It is especially suited for bonding small parts and for repair work.
No special techniques are required to work with this adhesive. Mix the two components thoroughly on a clean, dry surface. The bonding surface can be wood, metal, plastic or cardboard, among others. For best results, the two surfaces being bonded should be free of oil, dirt, moisture, etc. And should be slightly roughened or sanded to remove gloss.
The strength and durability of a bonded joint are dependent on proper pretreatment of the surfaces to be bonded. At the very least, joint surfaces should be cleaned with a good degreasing agent such as acetone or trichloroethylene, in order to remove all traces of oil, grease and dirt. Never use alcohol, gasoline or paint thinners. The strongest and most durable joints are obtained by either mechanically abrading or chemically etching (“pickling”) the degreased surfaces. Abrading should be followed by a second degreasing treatment.
Application of Adhesive
Apply the resin/hardener mix with a spatula to the pretreated and dry joint surfaces.
A layer of adhesive 0.002 to 0.004-inches (0.05 to 0.10-mm) thick will normally impart the greatest lap strength to a joint. The joint components should be assembled and clamped as soon as the adhesive has been applied. Event contact throughout ensures proper cure.
Storage and Shelf Life
Fastweld 10 A/B epoxy adhesive components should be stored in their original, sealed container at temperature between +2°C and +40°C (+36°F and 104°F). Under these storage conditions, the shelf life is 3 years. The product should not be exposed to direct sunlight. If stored below 60°F, the adhesive should be brought to 60°F – 77°F and conditioned at this temperature for some time prior to use.
