Construction adhesive refers to a broad range of similar products used to bond common materials used in the construction, renovation and finishing of homes.Of course, if you have shopped in a hardware store you know that some companies have adhesives they have named construction adhesive.hoosing the correct construction adhesive product can be confusing, since there is lots of functional overlap among them. Fortunately, the manufacturers are pretty good about listing the uses of their products on the labels.
The other method of evaluating adhesive strength is by shear adhesion strength measurement. According to standard EN 12004, the shear adhesion strength test method is only applied to resin-based dispersion adhesives (dispersion adhesives D, in the standard) and to reaction resin adhesives (reaction resin adhesives R, in the standard).
