Application
- Recommended application temperature from +5°C to +35°C.
- Apply the adhesive to clean, dry and degreased surfaces. One of the bonding surfaces should be porous.
- Cut off the tip of the cartridge above the screw thread, screw on the nozzle, unscrew the nozzle cap and cut off the nozzle diagonally (at an angle of 45°) according to the diameter of the joint width.
- Apply with a cartridge caulking gun.
- Apply the adhesive in a continuous coating or in dots of about 6 mm in diameter, depending on the work complexity.
- Apply the adhesive to one surface and leave it exposed to the air for 10-15 minutes to aid bonding. Then bring the surfaces together and press firmly.
- Touch-dry – not more than 120 minutes; repositionable within 30 minutes; ready to handle – 48 hours (depending on the porosity of bonded materials and the thickness of the adhesive layer) at a temperature of at least +23°C and 50% humidity.
- As an indicator of drying, the color of the adhesive changes from milky white to colorless.
- Remove uncured adhesive with a moist cloth.
- Remove the cured adhesive mechanically.
Note: Don’t apply to aquariums and underwater seals. Not for use at temperatures below +5°C and in high humidity (>70%).
