Construction adhesive

[1] It is most commonly available in tubes intended for use with a caulking gun.

[2] Adhesion to a variety of substrates allows bonding of dissimilar materials if necessary.

High elastic modulus of substrate and adhesive resists stress at the bond line.

Common ingredients include clay, cement, acrylic resin, polyurethane monomers, styrene-butadiene rubber, hexane and other nonpolar solvents, and various initiators and functional additives.

[6][7] ASTM C557 "Standard Specification for Adhesives for Fastening Gypsum Wallboard to Wood Framing" gives requirements for construction adhesives used for attaching wallboard in building construction.
