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

Adhesion
• GUIBAO 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, GUIBAO 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
• GUIBAO 661 can be applied manually.
Apply a bead of GUIBAO 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.
• GUIBAO 661 can also be applied with dispensing machines.
