Ideal for applications that require superior bond strength and moisture resistance, NovaFlex High Impact Glazing Sealant (M400 series) is designed primarily for glazing and back-bedding applications to meet the stringent requirements of the Dade County hurricane testing.
A cost-effective alternative to competitive 2-part sealants, structural tapes, and windshield urethanes, NovaFlex High Impact Glazing Sealant (M400 series) is a one-part neutral cure silicone sealant/adhesive with excellent adhesion to numerous substrates, formulated for impact protection and blast resistance.
- Neutral cure silicone
- High elongation and tensile strength
- Non-corrosive formulation
- Excellent chemical resistance
- Deep section cure
- Excellent adhesion to window and door substrates
- Utilized in window fenestration for impact resistant systems
- Miami-Dade approved (Part of an impact resistant window system)
NovaFlex High Impact Glazing Sealant (M400 series) is a non-corrosive, single-component silicone paste that cures upon exposure to atmospheric moisture to a rubber-like solid. It is specially formulated to retain its physical properties even in extreme environmental conditions.
Ideal for applications that require superior bond strength and moisture resistance, it is designed primarily for glazing and back-bedding applications to meet the stringent requirements of the Dade County hurricane testing. It is often used in window and door frame assembly and glazing/back bedding for impact-resistant window and door systems. It’s not recommended for joints continuously submerged under water nor areas needing paint or stain.
Meets or exceeds the performance characteristics of AAMA 802.3, 805.2 Group C, and 808.3 Type I.
