- Glue BK-9 - Epoxy-polyamide glue cold cure (cured at room temperature).
- Forms vakuumnoprochny seam.
- Resistant to water, alkalis, oils and gasoline.
Glue VK-9 is supplied 2-component.
Instructions for the use of VK-9 glue:
Wear gloves and use disposable dishes.
Bonded (working) material must be degreased with nefrasom BR-2. Normally processed unpainted metal black.
Then degrease with acetone or other solvent.
Stir thoroughly 2 components in the specified proportion.
Viability in mass at 20°C after mixing 2 components of glue ~ 2 hours.
Apply glue to the working surfaces at a flow rate of 100-150 g/m2.
Method of applying glue - spatula;
- number of layers - 1;
- open exposure - not required (permissible 1 min at a temperature of 18 to 23°C);
1) temperature from 18 to 23°C;
time - 24 hours;
pressure - 0,01 MPa;
