Tips from TEC7

• ROCK7 is ideal for applications with glass and/or heavy UV exposure.
• What´s the secret for perfectly finished joints? Smooth your seams and joints withTEC7 Cleaner. You get the best result when you use a joint spatula with a straight edge.
• Proper preparation is the secret of all professionals. Use FOAM7 as a universal degreaser/cleaner.
• For organic soiling and/or large surface areas, HP7 is your best degreaser.
• Use the ergonomic TEC7 Gun for processing ROCK7. This will save you from complaints resulting from RSI (repetitive strain injury).
• ROCK7 adheres less well on Polypropylene (PP), Polyethylene (PE), PTFE (Teflon®), bitumen and silicones. Always do an adhesion test.
• ROCK7 is ideal for transparent sealings. For bondings we recommend TEC7.
• Do you want to suspend heavy objects very precisely? X-TACK7 is your best choice for power assemblies where an extremely high initial tack is required.
• For anchorings and fast bondings we recommend 2-K MIX7.
• Cleaning tools: TEC7 Cleaner and/or MAGIC CLEAN7.
• Hand-cleaning_ MAGIC CLEAN7.
