STORAGE AND SHELF LIFE

GB 661 should be stored in original unopened containers. The shelf life is 9 months from the date of manufacture.

LIMITATIONS

GB 661 should not be applied

As structural sealant

In totally confined spaces

In continuous water immersion

When material surface temperature is below 4℃ or over 50℃.

HOW TO USE

Surface Preparation

All surfaces of the substrates must be clean and dry. All dust, grease, rust, etc. should be removed.

Adhesion

GB 661 has excellent unprimed adhesion to most substrates.

Priming or plasma processing is necessary for the low surface energy substrates such as PTFE, Polypropylene, Polyethylene

The cure time may extend when the sealant is applied into deep section or when the ambient temperature is low

Primer

For optimal adhesion, GB primer is recommended.

Clean the substrate surface with solvents and then apply a coat of primer by dipping, brushing or spraying.

Allow primer to dry for 5~10 minutes. Apply the silicone sealant onto the primer once the substrate surface a little sticky when touched with hand.

For special applications, drying in the shade, humidification and drying in the high temperature should be adopted to ensure the cure stability.

Application Method

GB 661 can be applied manually.

Apply a bead of GB LV 661 with a dispensing gun to one of the prepared surface, and then cover quickly with the other substrate to be bonded. If applied to deep section, especially when access to moisture is restricted, it takes longer to cure completely. And cure time is extend at lower temperature and humidity

GB 661 can also be applied with dispensing machines

SAFETY INFORMATION

Should uncured silicone sealant contact with eyes, rinse thoroughly with a lot of water and seek medical treatment if irritation persists.

Keep the uncured silicone sealant away from children.

Good ventilation is necessary for work and cure places.
