4. Setup and Preparation
Proper preparation is crucial for optimal performance of the adhesive/sealant.
4.1 Surface Preparation
Ensure all surfaces to be bonded or sealed are clean, dry, and free from grease, oil, dust, and other contaminants. For best adhesion, surfaces may require mechanical abrasion or chemical cleaning.
4.2 Nozzle Preparation
Before application, cut the tip of the nozzle to the desired opening size. A smaller opening provides a finer bead, while a larger opening allows for a thicker application.

5. Application Instructions
Apply the DOWSIL™ 3145 RTV Adhesive/Sealant directly from the tube onto the prepared surface. Since it is a one-part, room temperature vulcanizing (RTV) adhesive, no mixing is required. The sealant cures upon exposure to moisture in the air.
5.1 General Application
Dispense a continuous bead of sealant onto one of the surfaces to be joined or into the area to be sealed. Bring the surfaces together within the sealant's tack-free time. For optimal adhesion, ensure good contact between the sealant and both surfaces.
5.2 Curing
The sealant cures at room temperature by reacting with atmospheric moisture. Cure time will vary depending on humidity, temperature, and the thickness of the applied bead. Thicker applications will require longer cure times.
6. Storage and Handling
To maintain product integrity and performance, store the DOWSIL™ 3145 RTV Adhesive/Sealant in its original, unopened container in a cool, dry place. Ensure the cap is tightly sealed after each use to prevent exposure to moisture, which can initiate the curing process.
