    MasterSeal 740SPF - Spray applied polyurethane foam (SPF) for seamless, high performance thermal insulations

    What is MasterSeal 740SPF?

    MasterSeal 740SPF is a polyurethane spray foam system (in-situ foam) for the production of rigid foam with closed cells for thermal insulation.

    What is MasterSeal 740SPF used for?

    • Thermal insulation layer in building envelope; mainly on roofs, walls or cold stores where a seamless thermal insulation is required
    • Thermal insulation in industrial plants, storage tanks, containers, cargo ships, agricultural storage and all types of buildings.
    • The system can be applied on substrate like metal, plywood and concrete.
    • Suitability must be examined by the user prior to commercial use.

    What are the benefits of MasterSeal 740SPF?

    • Maximum thermal insulation – Maximum energy saving due to optimal insulation with no joints or thermal bridges
    • Fast reacting – Rapid installation. Does not run when applied on vertical surfaces.
    • Seamless – No risk of leaky seams and laps.
    • Spray applied - Fast installation on large surfaces, easy application on complex details.
    • Fully bonded – Eliminates water collection behind the foam and offers high wind uplift resistance.
    • High compressive strength – withstand necessary load
    • Quick Refurbishment - Usually no break-up of the old roof surface
    • Environmental friendly
