How to Use
Here are some general guidelines on how to use DOWSIL™ 732 Multi-Purpose Sealant:
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.
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.
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.
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.
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.
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.
Usable Life And Storage
Usable life: The usable life of DOWSIL™ HAOSHI NT Sealant is typically 12 months from the date of manufacture, provided it is stored properly (see below). It is important to use the sealant before the expiration date to ensure its effectiveness.
Storage: The sealant should be stored in a cool, dry place, away from direct sunlight and heat sources. It should be stored at temperatures between 5°C to 27°C (41°F to 80°F) to prevent the material from hardening or curing prematurely. The sealant should be kept in its original container and the lid should be tightly sealed to prevent air exposure.
Limitations
Here are some of the limitations of DOWSIL™ HAOSHI NT Sealant:
Paintability: This sealant may not be compatible with all types of paint, and it is important to test compatibility before painting over the sealant.
Non-porous surfaces: It is not recommended for use on non-porous surfaces, such as polished or glazed surfaces, as it may not adhere well.
Structural bonding: This sealant is not recommended for use as a structural adhesive, and it should not be used to support heavy loads.
Cold temperature application: It should not be used in applications where it will be exposed to temperatures below -40°C (-40°F).
Food contact: This sealant is not recommended for use in food contact applications.
Submerged applications: It is not recommended for use in submerged applications or below the waterline.
