This specification covers the requirements for chemical-resistant resin mortars for bonding chemical-resistant brick or tile. Mortars of this group generally have better physical properties and resist a wider variety of chemicals than inorganic mortars. The liquid resin may be phenolic, furan epoxy, polyester, vinyl ester, or some other resinous material capable of forming a chemical-resistant mortar when mixed with a suitable setting agent and filler. The fillers may be silica, carbon, or some other chemical-resistant material. The setting agents may include amines, polyamides, peroxides, acids or other reactants. Setting agents may be supplied as a separate component to be incorporated into the resin and filler at the time of mixing or may be supplied as a constituent of the filler. The resin shall be tested and should conform to the specified values of viscosity, chemical resistance, working life and setting time, tensile strength, compressive strength, bond strength, shrinkage, and absorption.

1.1 This specification covers the requirements for chemical-resistant resin mortars for bonding chemical-resistant brick or tile. Mortars of this group generally have better physical properties and resist a wider variety of chemicals than inorganic mortars. For the use of these materials, see Practice C 399. Note 1Resin mortars and grouts are differentiated as follows: resin mortars are troweled onto the brick or tile, in sufficient quantity to achieve a 1/8-in. (3-mm) thick joint after the brick or tile are laid in place (buttering or bricklayer's method). Resin grouts are applied to the joints, generally 1/4in. (6 mm) wide, after the brick or tile are set in place and the setting bed has hardened (grouting or tilesetter's method). Refer to Specification C 658.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
