3M™ Scotch-Weld™ Epoxy Adhesive EC9323 B/A
3M™ Scotch-Weld™ Epoxy Adhesive EC9323 B/A is a two component epoxy paste adhesive which cures at room temperature or with mild heat to form a tough, impact resistant structural bond. It has an excellent adhesion to a wide variety of substrates such as metals, glass, ceramics and plastics, incl. GFRP and CFRP. Once cured it provides extremely high shear and peel strength over a wide temperature range, with outstanding resistance to harsh environments and chemicals commonly encountered in aerospace applications.
Details
- Cures at room temperature of 20-25°C (cure rate may be accelerated by the application of mild heat).
- Red orange in colour.
- Convenient mix ratio.
- Mixed adhesive is non-flow for ease of application.
- High impact resistance.
- High environmental resistance.
Application
- This product consists of two parts. Combine Part B and Part A in a separate container just prior to application in the proportions specified. Note: Mix ratio deviations above +/- 5 % have significant influence on material performance.
- Mix both components thoroughly until a uniform colour is obtained. Important: Be careful when mixing quantities larger than 100 grams, because exothermic reaction may occur.
- Apply adhesive to parts to be bonded before the work life expires, e.g. by spatula. Note: Work life depends to some extent on mixed quantity and the shape of the container.
- Use of a shallow container will minimize the quantity impact. In order to obtain optimum mechanical performance, the joint components should be assembled and clamped as soon as the adhesive has been applied and before end of the work time.
- A fixation of the joint and an even contact pressure throughout the joint area during cure will ensure optimum performance. Maximum shear strength is obtained with 0.10 – 0.20 mm bond line thickness.
- Close the containers after use to protect the material against humidity.
Cleaning
Excess uncured adhesive can be cleaned with ketone type solvents. After cure, the adhesive can be removed mechanically. NOTE: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and instructions for use.
