What EXACTLY Is The GSM Iron Sentry System?

What is GSM?

The "Iron Sentry™" roofing system is a product that was specifically designed for today's demanding needs of commercial roofing. Our products help you seal and protect practically any roofing surface including concrete, metal, EPDM, built-up and more.

As opposed to a built-up structural roofing system, the Iron Sentry roofing system is brought to your roof in liquid form and is manufactured on your roof to its final seamless form and adhered chemically to your current roof system. The bond formed is both a sealer and insulation barrier (qualifies for Federal Tax Credits) that has been tested and proven to create a minimum of 30% energy reduction in heating or cooling costs for the building.

The Iron Sentry base coat product is a two component system of one to one mix and is called Iron Sentry™ 121 - Depending on how it is applied, either with specialized applicators or through our custom heated two part controlled spray application, the finished product is always consistent with the thickness of the material constantly monitored and tested for quality control during the application process.

We offer both a silver and white topcoat. They both have great reflectivity exceeding 80%, abrasion resistance and have a class A fire resistance on non-combustible surfaces.

The white topcoat is a pure liquid vinyl and simply called Iron Sentry™ 1535B or White Aliphatic Coating. The white topcoat has the ability to withstand foot traffic and many abrasive events such as the replacement of an air conditioning unit without damaging the surface of the coating. If the surface becomes damaged, then a repair of the coating does not create a patch (as in structured roofing applications) and the roof remains seamless with its original intergrity. The silver topcoat is called Iron Sentry™ 1401 - Silver Aromatic Coating a single component, moisture cure, polyurethane coating. This coating is typically used on metal roofing and can also be used over all other types of existing roofs if desired.

Iron Sentry™ 121 – Hand Mix Polyurethane Sealer (viscosity adjusted on batch mixing for small surfaces) Iron Sentry™ Hand-Mix Sealer is an exterior grade, two component, reactive cure, polyurethane sealer. It is designed for use as a surface coating where durability, high abrasion resistance, flexibility and low life cycle costs are required. When properly applied, it has outstanding adhesion to metal, urethane foam, EPDM rubber and most other conventional roofing surfaces. Iron Sentry™ Sealer resists the effects of mold, mildew, fungus and other parasites.
Iron Sentry™ 121 – Spray Polyurethane Sealer (viscosity engineered for special close surface spray application equipment) Iron Sentry™ Spray Sealer is an exterior grade, two component, reactive cure, polyurethane sealer. It is designed for use as a surface coating where durability, high abrasion resistance, flexibility and low life cycle costs are required. When properly applied, it has outstanding adhesion to metal, urethane foam, EPDM rubber and most other conventional roofing surfaces. Iron Sentry™ Sealer resists the effects of mold, mildew, fungus and other parasites.
Iron Sentry™ 1401 - Silver Aromatic Coating The Iron Sentry™ Silver Aromatic Coating is an exterior grade, single component, moisture cure, polyurethane coating. It is designed for use as a surface coating where reflectivity, durability, high abrasion resistance, and low life cycle costsare required. When properly applied, it has outstanding adhesion to metal, urethane foam, and most other conventional roofing surfaces. Iron Sentry™ Silver Aromatic Coating also resists the effects of mold, mildew, fungus and parasites.
Iron Sentry™ 1425B MAC Primer The Iron Sentry™ MAC Primer is intended for use as an adhesion promoter for Iron Sentry™ Sealers, Iron Sentry™ Silver and Iron Sentry™ White roof coatings to metal, asphalt materials and concrete roof surfaces. It is a clear to amber viscous liquid and has a very minimal aromatic odor at room temperature.
Iron Sentry™ 1535B – White Aliphatic Coating The Iron Sentry™ White Aliphatic Coating is an exterior grade, single component, moisture cure, polyurethane coating. It is designed for use as a surface coating where reflectivity, durability, high abrasion resistance, and low life cycle costs are required. When properly applied, it has outstanding adhesion to metal, urethane foam, and most other conventional roofing surfaces. MCPU White Aliphatic Coating also resists the effects of mold, mildew, fungus and parasites.
Iron Sentry™ Rust Neutralizer/Cleaner The Iron Sentry™ Rust Neutralizer/Cleaner is intended for use as a pre-application treatment to neutralize rust on metal roof surfaces, screws & fasteners and flashing. It is intended to neutralize existing rust prior to encapsulation by The Iron Sentry™ Roof Coating System minimizing rust migration under the new roof coatings.
