Tremsil 200: Acetoxy Silicone Sealant

Tremsil 200 produces a weathertight seal to glass, metal, porcelain, ceramic and most painted surfaces. Tremsil 200 sealant is suitable for use in kitchens, bathrooms, spas and similar applications.

Substrate Preparation

For good adhesion, the joint interface must be sound, clean and dry. Depending on the substrates, the joint surface may require a thorough wire
bushing, grinding, sandblasting, solvent washing and/or primer. Tremco recommends that air temperatures be 40 °F (5 °C) or above before
applying any sealant.


Tremsil 200 is easy to apply with conventional caulking equipment. Fill joint completely and tool. At 75 ˚F (23.9 ˚C), 50% RH, a durable skin will form
within 30 min.

Joint Design

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.

Join Backing

Closed-cell polyethylene, reticulated foam and some open-cell polyurethane
rods may be used as joint backing to control depth of sealant bead. Where
depth of joint will prevent use of joint backing, an adhesive-backed
polyethylene tape should be installed to prevent three-sided adhesion. Joint
backing must be dry at time of sealant application.

Sealant Dimensions

For joints 1/4″ (6 mm) to 1/2″ (13 mm) wide, the width to depth ratio should be
equal. Joints 1/2″ (13 mm) wide or greater should have a depth of 1/2″ (13
mm). Minimum joint size is 1/4″ x 1/4″ (6 mm x 6 mm).

Clean Up

Tooling is recommended immediately after application to ensure firm, intimate
contact with the joint interface. Dry tooling is preferred. Cleaning can be
accomplished with solvents such as IPA, Xylol, Toluene or MEK while sealant
is in uncured state.


  • • Do not apply over damp or contaminated surfaces.
  •  Use with adequate ventilation.
  •  Not intended for continuous water immersion.
  •  Do not use on surfaces sensitive to corrosion by acetic acid vapors (a byproduct of sealant cure).
