Who Is This For?
Window and curtain-wall installers, fabricators and maintenance crews sealing white or light-colored joints that have to move, and anyone working indoors or in occupied buildings where the vinegar smell of an acid-cure silicone is a problem.
What This Is Not For
Silco publishes no paintable claim for its silicone lines, so where the bead has to be painted over, the Silco Eco-Flex 9500 Hybrid Adhesive Sealant is the product Silco does publish as paintable. Where the published mildew-resistance claim matters, that claim belongs to the acetoxy Silco Sil-Bond RTV-3500 Silicone Sealant in white, not to this line.
Frequently Asked Questions
Is white a standard color for this line?
Yes. Silco publishes clear, white, black and aluminum as standard colors for Sil-Flex RTV-7500, with almond, bronze, gray and trans white available as customs.
Why choose a neutral cure over an acetoxy silicone?
A neutral cure silicone cures without releasing acetic acid, so it has little odor during application. Silco gives the Sil-Flex RTV-7500 cure system as neutral/oxime and publishes the line as non-corrosive and low odor.
What specifications does it meet?
Silco publishes Sil-Flex RTV-7500 as meeting ASTM C920 Type S, Grade NS, Class 50, TT-S-00230C, TT-S-01543A, MIL-A-46106A, AAMA 808.3 and 803.3 (Type II), and as a UL Recognized Component.
What size is the cartridge and where does that figure come from?
Sil-Flex RTV-7500 is sold in a 10.3 oz. cartridge. That size is published by distributors rather than by Silco, which shows its packaging data only as an image.
