Silco Sil-Bond RTV-3500 100% Silicone Sealant – 10.3 oz. Cartridge, Trans White, Acetoxy Cure
Silco Sil-Bond RTV-3500 100% Silicone Sealant – 10.3 oz. Cartridge, Trans White, Acetoxy Cure
The Silco Sil-Bond RTV-3500 Silicone Sealant in trans white is a one-component acetoxy cure silicone in a 10.3 oz. cartridge, and is a translucent color rather than the opaque white in the same line.
Key Features
- Trans white is translucent: the bead takes on the tone of the substrate instead of covering it. It is a different color from the opaque white in this line.
- Acetoxy cure, published on Silco's own data sheet and by its Acetoxy Cure category. Acid cure, with the vinegar odor while it sets.
- Published as mildew resistant, UV stable, non-yellowing, non-shrinking and waterproof, with excellent weatherability and adhesion.
- Silco publishes the color family as Trans Colors and never uses the word translucent, so the color name stays trans white.
- Silco publishes adhesion to metal, steel, tile, fiberglass, ceramic, glass, aluminum, painted surfaces, wood, plywood and marble among other common substrates.
- 10.3 oz. cartridge for a standard cartridge caulking gun.
Who Is This For?
Tile setters and fabricators who want a soft, milky joint line on light stone, tile and glass rather than a solid white stripe, and shops matching a translucent bead to a veined or mottled surface.
What This Is Not For
Trans white will not hide a wide or ragged joint the way an opaque bead does; the opaque white in this same line is the one that covers. Silco also publishes no paintable claim for this silicone, so a joint that has to be painted needs the Silco Eco-Flex 9500 Hybrid Adhesive Sealant, which is published as paintable.
Frequently Asked Questions
Is trans white the same as white?
No. Trans white is a translucent color that lets the substrate show through the bead; white is opaque and covers it. Silco publishes both for the Sil-Bond RTV-3500 line.
Why is it called trans white and not translucent white?
Silco's own published wording is Trans Colors and trans white. The company never prints the full word translucent, so the color name is kept as Silco writes it.
What cure system does it use?
Silco publishes Sil-Bond RTV-3500 as an acetoxy cure silicone, an acid cure that gives off acetic acid, and therefore a vinegar smell, while the bead sets.
Is it mildew resistant?
Yes. Silco's data sheet for the line is headed SIL-BOND RTV-3500 (Acetoxy) Mildew Resistant, and its site lists SIL-BOND 3500 as a mildew resistant sealant.
