How to Use

Here are some general guidelines on how to use DOWSIL™ 732 Multi-Purpose Sealant:

1. Surface preparation: Clean the surface to be sealed or bonded thoroughly, removing any dirt, dust, oil, or other contaminants. Ensure the surface is completely dry before applying the sealant.
2. Cut the nozzle: Cut the nozzle of the sealant tube to the desired size and puncture the inner seal. Install the cartridge into a standard caulking gun.
3. Apply the sealant: Apply the sealant to the prepared surface in a continuous and uniform manner. Tool the sealant with a wet finger or spatula to ensure a smooth, even finish.
4. Curing time: DOWSIL™ 732 Multi-Purpose Sealant cures quickly at room temperature upon exposure to moisture in the air. The cure time will depend on the temperature, humidity, and thickness of the sealant layer.
5. Clean up: Clean any excess sealant with a clean cloth before it cures. If the sealant has already cured, it can be removed mechanically or with a solvent.
6. Storage: Store the sealant in a cool and dry place, away from direct sunlight and heat. Ensure that the sealant tube is sealed properly to prevent it from drying out.

Cure Time

DOWSIL™ 732 Multi-Purpose Sealant cures quickly at room temperature upon exposure to moisture in the air. The cure time will depend on several factors, including the temperature, humidity, and thickness of the sealant layer. At standard temperature and humidity conditions (77°F/25°C and 50% relative humidity), DOWSIL™ 732 Multi-Purpose Sealant typically skins over in about 15-25 minutes and cures to a depth of 1/8 inch in 24 hours. However, the cure time can vary significantly depending on the specific application conditions.

Compatibility

DOWSIL™ 732 Multi-Purpose Sealant is compatible with a wide range of materials, including glass, ceramics, metals, plastics, and wood. However, it is always recommended to conduct compatibility tests before using the sealant in your specific application.

Usable Life and Storage
When stored in its original, unopened container at or below 32°C (90°F), the shelf life of DOWSIL™ 732 Multi-Purpose Sealant is 12 months from the date of manufacture. However, if the product is exposed to high temperatures or moisture, its shelf life may be significantly reduced.
