PAINTING INSTRUCTIONS (Contd)
b. Application of Components.
Coat all individual parts with separating agent on the sealing surfaces. Apply a 0.04 in (1 mm) thick
layer with a toothed plastic spatula.
Assemble steel parts with prescribed torques. Separating agent must exude from all sides. Remove
The hardening speed and the bonding structure of GD 677 essentially depend on the storage
temperature of the parts manufactured with it. At 50F (10C), the hardening times are doubled to
tripled, and they are shortened by about half at 86F (30C). A non-tacky surface is achieved after
approximately 5 hours at 75F (23C).
Hardening development at 75F (23C) on basis of the increase of Shore A Hardness:
Shore A (+/-4) 5
d. Operation of Automatic Mixer.
To ensure mixing of proper proportions, completely empty the can.
Add component B (black) (8) to component A (2).
Insert tin containing component A (2) in the retaining tin (3) and secure the tension lock (4).
Mount spiral stirrer (6) in drill (9).
Components should be sufficiently homogeneously blended after
approximately 5 minutes.
To ensure proper bonding, component mixture must be used within
40 minutes at 68F (20C).
Blend component B (8) in the upper third of the tin containing component A (2). Proceed slowly to
the bottom of the tin, stirring in an even, counterclockwise direction.
e. Filling the SVV 50 Gun.
Insert the pressing plate (1) into the tin containing component mixture (10). Press plate (1)
downwards until the opening in the center of the plate is filled with sealant.
Remove nozzle head of the SVV 50 gun (7) and insert the gun (7) into the center opening of the
pressing plate (1).
Position red valve lever, located at bottom of gun handle, for suction mode.
For most efficient suction of component into gun, ensure gun
remains in as perfect of a perpendicular position as possible.
When pressing plate comes to a standstill, the gun tube is filled
Actuate gun trigger and press gun securely against pressing plate (1). Pressing plate (1) will begin
Release gun trigger and shift red valve lever (5) to pressure position.
Apply component per task b, step 1.
