RG-12B adhesive film:
High bonding strength,
fracture toughness,
wet and heat aging resistance,
fatigue resistance,
RG-12B adhesive film is suitable for lead, copper (stainless steel), galvanized sheet, titanium, resin matrix composite materials bonding load-carrying structure.Especially the board - plate, the plate - core structure of cementing compatibility, can be used under - 20 ℃ -- 90 ℃.At present, it is mainly used in various civil honeycomb sandwich structures such as aramid honeycomb, locomotive floor and door, aluminum curtain wall, fire prevention board and aluminum plate.

Curing conditions:
Temperature 120-125 ℃, 1-0.3 Mpa pressure, time 1 to 2 h, after the curing process should be cooled to below 60 ℃ direction unloading out parts.Can also be cured at 150 ℃, 1-0.3 Mpa pressure, time is 10 min, can immediately after take out, but the honeycomb climb loosened stripping performance is 120 ℃ curing performance has a certain degree of decline (see chart)
Supply status: knitted nylon gauze or glass felt carrier film, width 300-1300 passwords, 100 meters long
Packing: glue film to prevent sticky paper from the insulation layer, after polyethylene bag sealing and then into the carton.
Transportation: according to the transport of dangerous goods, transport no more than 10 days or under 4 ℃ under 25 ℃ not more than 5 days.
Storage: film under the condition of the original sealed package should be stored in low temperature environment, since the production date, shelf life for the under - 18 ℃ 9 months or three months under 4 ℃, include up to 25 ℃ of total external time 20 days.
