Silco Eco-Flex 9500 Hybrid Adhesive Sealant – 20 oz. Foil Sausage, White
Silco Eco-Flex 9500 Hybrid Adhesive Sealant – 20 oz. Foil Sausage, White
The Silco Eco-Flex 9500 Hybrid Adhesive Sealant is a one-component, high-modulus hybrid moisture-cure sealant and adhesive based on silyl-terminated polyether, supplied here as a single 20 oz. white foil sausage.
Key Features
- Hybrid moisture cure, published by Silco as cure system Hybrid, Moisture Cure. It is a silyl-terminated polyether, not a polyurethane and not a silicone.
- Contains no solvents and no isocyanates, per Silco's published product data.
- Paintable, and published as non-yellowing and non-staining.
- VOC content 18 g/L and VOC compliant. High modulus by ASTM D-412.
- Silco publishes adhesion to PVC, concrete, glass, aluminum, painted surfaces, wood, plywood, marble and metal among other common substrates.
- This item is one 20 oz. foil sausage, which loads into a bulk or sausage gun, not a cartridge gun.
Who Is This For?
Fabricators and installers who want one product that both bonds and seals: panel and trim bonding, perimeter joints, sink and splash work, and exterior joints on mixed substrates. The single sausage suits a shop trying the product or finishing one job rather than buying a case.
What This Is Not For
A 20 oz. foil sausage will not load into an ordinary cartridge caulking gun; without a bulk gun on the truck, a cartridge product such as the Silco Sil-Flex RTV-7500 Silicone Sealant in white is the practical choice. Where the requirement is specifically a silicone rubber joint rather than a hybrid, either Silco silicone line is the right family. If the job needs a full case, buy the 16-sausage bundle of the same product instead.
Frequently Asked Questions
Is Eco-Flex 9500 a polyurethane?
No. Silco publishes Eco-Flex 9500 as a hybrid, moisture cure sealant and adhesive based on silyl-terminated polyether, and states it contains no solvents or isocyanates. Describing it as a polyurethane is a chemistry error.
Can it be painted?
Yes. Silco publishes Eco-Flex 9500 as paintable, along with non-yellowing and non-staining. Silicone sealants generally are not paintable, which is the practical reason to choose the hybrid.
What gun does a 20 oz. foil sausage need?
A foil sausage needs a bulk or sausage gun, which holds the foil pack in a barrel and takes a separate nozzle. A standard cartridge caulking gun will not accept it.
What is the VOC content?
Silco publishes the VOC content of Eco-Flex 9500 as 18 g/L and describes the product as VOC compliant. No LEED, GreenGuard or ISO certification is published for it.
How long does it take to cure?
Silco publishes no tack-free or full-cure time for Eco-Flex 9500 in the sources on file. It is a moisture-cure hybrid, so cure depends on humidity, temperature and bead depth.
