Variation in the Proportion of the A and B Components of 'Honeymoon' Adhesive Systems Used for Exterior Grade Finger Joints

摘要

In the 'Honeymoon' adhesive systems the A component contains hardener so that an excess of A over B component, or lack of the B component will result in slow curing but to a satisfactory strength. The B component does not contain hardener and therefore an excess of B component over A component could result in very little or no curing. For this reason a wattle-tannin based and a phenolic fast-setting 'Honeymoon' adhesive system were tested to determine the maximum variation in proportion of B to A component at which the cured strength of the adhesive would be unaffected.
