Tremsil 200
Tremsil 200 is a single-component, acetoxy silicone sealant, cures to a flexible rubber when exposed to moisture present in the air.
Tremsil 200 is a silicone sealant from Tremco. Tremco lists it for kitchens, bathrooms, spas. Tremco gives the application temperature as 5 to 40 °C (41 to 104 °F), which the product and the surface both have to meet on the day. Cranco carries it, and which counter has it on the day changes, so ask at the counter.
Tremsil 200 is Tremco's single-component acetoxy silicone for kitchens, bathrooms and spas. It seals to glass, metal, porcelain, ceramic and most painted surfaces, skins in 20 minutes, takes 25% movement under ISO 11600, and conforms to ASTM C920 Type S Grade NS Use NT, G, A and O plus CAN/CGSB-19.13-M87.
Its Greenguard Gold certification is the reason it goes into hospitals and schools. Cranco carries Tremco at Concord, Barrie and Mississauga. Call the branch to confirm the colour and size in stock, and the price.

FEATURES AND BENEFITS
- Tremsil 200 is easy to apply with conventional caulking equipment.
- Tremsil 200 may be used in any joint designed in accordance with accepted architectural/engineering practices.
- Joint width should be 4 times anticipated movement, but not less than 1/4" (6 mm) wide.
- Tremsil 200’s Greenguard Gold certification ensures safety for use in the most sensitive indoor environments including hospitals and schools.
What is Tremsil 200 used for?
Kitchens, bathrooms, spas and similar work. Tremco says it produces a weathertight seal to glass, metal, porcelain, ceramic and most painted surfaces.
Is Tremsil 200 safe for indoor use?
Tremco's own sentence is that the Greenguard Gold certification ensures safety for use in the most sensitive indoor environments including hospitals and schools. Tremco still says to use it with adequate ventilation while it cures, because an acetoxy silicone gives off acetic acid vapour.
Will Tremsil 200 corrode metal?
Tremco rules it out on surfaces sensitive to corrosion by acetic acid vapours, which are a by-product of the cure. Copper, brass, lead and some galvanised finishes are the usual ones a contractor watches. Where the metal is a question, Tremsil 400 is Tremco's neutral-cure silicone in the same range.
What joint size does Tremsil 200 take?
Tremco's rule is a joint width of four times the anticipated movement, and never less than 1/4 inch, 6 mm, wide. The sealant is rated 25% movement, so a joint expected to move 1/16 inch wants a 1/4 inch bead.
What is the cure time for Tremsil 200?
Tremco lists a skin-forming time of 20 minutes. The data sheet Cranco holds gives no tack-free or full-cure time. Confirm the required cure and return-to-service time with Tremco before using the joint.
How cold can you apply Tremsil 200?
Between 5 and 40 °C, which is 41 to 104 °F. Cured, it holds from -40 to 100 °C.
What colours and sizes does Tremsil 200 come in?
Aluminum, black, clear, dark bronze, gray and white, in 300 mL cartridges. The colour chart and the data sheet are both linked at the foot of this page.
