EC 3535 B/A is a two component, polyurethane adhesive which cures very rapidly at room temperature or with heat to form tough, impact resistant structural bonds. |
| |
| It provides excellent adhesion to many primed or painted metal and plastic substrates and is designed to develop sag resistance approximately 30 seconds after mixing. |
| |
| EC 3535 B/A provides flexible bonds of many plastics and rubber. |
| |
| |
3M brand primer EC 1945 B/A is suggested for use on metal surfaces to achieve maximum resistance to water, humidity and salt spray. |
| |
|
| For best results it is also suggested that the primer itself or primed/adhesive system is heat cured. |
