STORAGE AND SHELF LIFE
GB 661 should be stored in original unopened containers. The shelf life is 9 months from the date of manufacture.
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
All surfaces of the substrates must be clean and dry. All dust, grease, rust, etc. should be removed.
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
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.
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
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.
