C-BOND: 255

C-BOND 255 Two-Component Flexible Silicone Adhesive

PPG C-BOND 255 is a general purpose silicone adhesive. It is a two component material requiring a heat cure, but does not need exposure to air or to moisture for curing. Adhesion to metals, plastics, glass and ceramics is excellent.

PPG C-BOND 255 adheres well to silicone rubber, and is the recommended adhesive for bonding silicone-based PPG C-RAM sheets, such as the FLX, GDSS and RGD-S grades.

PPG C-BOND 255 is available as a two-part kit comprising Part A and Part B, in the following sizes:

  • 1 lb PINT (0.46 kg)
  • 2 lb QUART (0.91 kg)
  • 8 lb GALLON (3.60 kg)

Consult Cuming Microwave for bulk orders.

Unopened containers, if stored at room temperature, should have a shelf life of at least 6 months.
