ARMSTRONG PRODUCT General Purpose Epoxy

Armstrong C-7 Epoxy Resin Adhesive with Activator “A” & “E” Description C-7 Resin with either Activator “A” or “E” produces an adhesive with a very rigid glue line. Although these systems do not exhibit high tensile shear strengths as other Armstrong adhesives do, they have proven very useful where a rigidity is required - such as bonding strain gages transducers and other strain measuring elements. By adding various fillers and reinforcing agents, these systems become applicable for many casting applications requiring good duplications and dimensional stability. The chemical and solvent resistance of the C-7 resin with the amine activators is exceptionally good.

Activator “A” is a fast reacting type which, when mixed at a ratio of 8 parts of activator to 100 parts (by weight) of the C-7 resin, gives a fast initial set time. It is recommended for use when curing is to be done at room temperature. More rapid cures can be accomplished, however, within 2 hours at 165°F. Activator “E” is mixed at the ratio of 6 parts of activator to 100 parts (by weight) of the C-7 resin. This is a slow reacting type especially for curing at elevated temperatures. Full cure is obtained in 1 hour at 200°F. This activator is not recommended for room temperature curing.
