FOSTER 30 – 80 VAPOR-SAFE® COATING is a water base, fire-resistive, flexible, high solids vapor barrier finish for most types of thermal insulation, including polystyrene foam

FOSTER 30-36 MA Coating is a white, fire resistive, tough, washable, abrasion-resistant indoor coating specially formulated for marine applications with thermal insulation.

FOSTER FOAMSEAL 30-45N Sealant is a gray vapour barrier sealant designed for use with rigid thermal insulation including polystyrene foam. It remains flexible in joints and will not shrink or crack during repeated cycles of high and low temperatures.

FOSTER WEATHERITE MASTIC 46-50 is a fibrated water-based breather mastic. It features a bright white colour and extremely smooth, creamy, thixotropic consistency for fast, easy application.

FOSTER MONOLAR II Mastic 60 38/60 39 based on chlorosulfonated polyethylene rubber (formerly known as Hypalon®*) is a tough, flexible, fire-resistive elastomeric finish for protection of thermal insulation. It is also used as a vapor barrier finish for fittings. It is excellent for outdoor use where good color retention, chemical resistance, and durability are required.

FOSTER MONOLAR Coating 60 95/60 96 is a tough flexible fire-resistive elastomeric finish for protection of outdoor thermal insulation. It contains chlorosulfonated polyethylene rubber (formerly known as Hypalon®*). It is an excellent vapor barrier for low temperature insulation on tanks, pipework, vessels, ductwork, and fittings

FOSTER C.I. MASTIC 60 25/60 26 is a tough, durable, high solids vapor barrier asphalt cutback mastic. Because of its low vapor permeance, it is an ideal surface coating for low temperature insulation on outdoor applications.

FOSTER MONOLAR Mastic 60 90/60 91 is a tough, flexible, and fire-resistive elastomeric finish for protection of outdoor thermal insulation. It contains chlorosulfonated polyethylene rubber (formerly known as Hypalon®*). It is an excellent vapour barrier for low temperature insulation on tanks, pipework, ductwork, vessels, and fittings

Foster Vapor-Fas 62-05 is a flexible vapor barrier jacketing material designed for use over insulation on commercial ductwork, piping and equipment. It is comprised of a 5-ply aluminium and polymer laminated film with an aggressive pressure sensitive adhesive and release liner.

FOSTER FIRE RESISTIVE C.I. Mastic 65 05 is a tough, durable, high solids vapour barrier and weather-coating for the protection of thermal insulation in outdoor service. Its excellent weather and fire resistance makes it suitable for use in place of conventional asphalt cutback mastic. It is an ideal surface coating for low temperature insulating applications where the insulation used is not affected by mild solvents.

FOSTER Fibrous Adhesive 81 27 is a sodium silicate based incombustible adhesive for bonding calcium silicate andexpanded perlite thermal insulation to itself and to nonporous surfaces. It offers maximum adhesion and optimum working qualities and it forms a hard, brittle, incombustible film.

FOSTER Fire Resistive Adhesive 81 33 is a superior adhesive for cementing thermal insulation to all structural surfaces. It is quick-setting, with good specific adhesion to iron, steel, aluminium, and most thermal insulations. Can be used without mechanical fastening for marine hull insulation.

FOSTER Adhesive/Sealant 81 84 is a two-component, high strength thermosetting urethane adhesive containing no flammable solvents. It is designed to bond various types of low-temperature insulation to themselves and to metal and masonry substrates. After curing, it forms a strong, yet flexible bond capable of withstanding thermal shock and mechanical impact

FOSTER FIRE RESISTIVE LAGGING ADHESIVE AND COATING 81 42 is a quick-setting water-based adhesive and coating used indoors to adhere and size canvas, glass cloth or other lagging fabric over pipe and duct insulation. It is also used to attach woven glass fiber tape to the joints of hard fibrous glass insulation board. This product is designed for marine and industrial use, and may be top-coated with solvent-based paints.

FOSTER CRYOGENIC ADHESIVE 82 77 is a chemically-curing composition which develops high tensile strength and adhesion, at room temperature, to a variety of surfaces including metal, wood, and masonry. It is supplied at virtually 100% solids enabling immediate bonding between non-porous surfaces without solvent entrapment problems.

FOSTER QUICK-TACK Adhesive 85 60 is a high tack, rapid setting water-base adhesive designed for bonding low density (up to 3#/cu. ft.) duct liner, duct wrap and fibrous glass insulations to painted or unpainted steel, galvanized or aluminium surfaces.

FOSTER Cryogenic Coating 90 66 is a two part black elastomeric coating designed for use in cryogenic and specific chemical resistance applications. It is suitable for application to polyurethane foam, polyisocyanurate (PIR) foam, cellular glass and fibrous glass insulations in conjunction with aluminium, steel, wood and masonry construction materials.

FOSTER ELASTOLAR Sealant 95 44 is a fire resistive, flexible butyl elastomer based vapor barrier sealant. It is designed for sealing joints in insulation (except polystyrene foam), metal, and masonry wherever maintenance of a water-tight and air-tight seal is required. It can be used as a joint sealant in low velocity duct air-conditioning systems. It is ideal for sealing the laps of aluminium jacketing to prevent the entrance of moisture.

FOSTER FLEXTRA Sealant 95 50 is a one component, elastomer based product used as a vapour barrier sealant in the joints of cellular glass and urethane foam board stock insulations. It remains soft and flexible, preventing damage to the insulation due to thermal cycling through a wide range of temperatures.

FOSTER MULTI-PURPOSE ADHESIVE 97 15 is a high tack, rapid-setting water based adhesive for bonding polystyrene foam insulations (extruded and bead board), fibrous glass insulation and PIR/polyurethane board stock insulations to concrete, masonry, gypsum board, and other porous substrates. It is also ideal for bonding fibrous insulations to painted or unpainted steel, galvanized or aluminium surfaces.

Foster C.I. Wrap™ 30 is a 30 mil flexible vapor retarder sheet membrane. It is comprised of a synthetic, rubber modified asphalt laminated to a tough polymer film and a treated peel and stick release liner. It is available in 4” and 35.5” widths

Foster C.I. Wrap™ 50 is a heavy duty 50 mil flexible vapor retarder sheet membrane. It is comprised of a synthetic, rubber modified asphalt laminated to a tough polymer film and a treated peel and stick release liner. It is available in 4” and 36”* widths.

MAST-A-FAB 42 24 has a synthetic fiber composition that provides for significantly greater elongation,recovery, and freedom from stress breakage. Glass cloth has virtually no elongation and breaks sharply under stress.
