IMS Fire Resistive Adhesive is a superior adhesive for cementing thermal insualtion to all structural surfaces. It is quick-setting, with good specific adhesion to iron, steel, aluminium, and most thermal insulations. It can be used without mechanical fastening for marine hull insulation.

IMS Fire Resistive Adhesive is the preferred adhesive for use with rigid polyurethane insulations. It can be used as a fabricating adhesive in making fittings, as a joint sealer and adhesive in the joints of polyurethane insulation, and as an adhesive to attach insulation to equipment surfaces. Bonds of polyurethane to itself made with 81-33 are stronger than the base insulation.

IMS Fire Resistive Adhesive withstands continuous surface temperatures up to 149°C (300°F), but it has been subjected to higher temperatures for short intervals with good results. Its excellent resistance to water and high humidity makes it a good sealing compound for joints and seams of insulation on cold water piping and equipment.

IMS Fire Resistive Adhesive meets the requirments of Military Specification MIL-A-3316C/D, Class 3, Grade A.

IMS Fire Resistive Adhesive contains no asbestos, lead, mercury or mercury compounds.
