APPLICATIONS

• General industrial sealing and bonding applications
• Complies with MIL-A-46106 and FDA 177.2600

How to use

• All surfaces must be clean and dry. Degrease and wash off any contaminants that could
  impair adhesion. Suitable solvents include isopropyl alcohol, acetone or methyl ethyl
  ketone.
• Unprimed adhesion may be obtained on many substrates such as glass, metals and most
  common engineering plastics. Substrates to which good adhesion is normally not obtained
  include PTFE, polyethylene, polypropylene and related materials.
  However, for maximum adhesion, the use of DOWSIL™ 1200 OS Primer is recommended.
• After solvent cleaning, a thin coat of DOWSIL™ 1200 OS Primer is applied by dipping,
  brushing or spraying. Allow primer to dry for 15 to 90 minutes at room temperature and a
  relative humidity of 50% or higher.

How to Apply

• Apply DOWSIL™ 732 Multi-Purpose Sealant to one of the prepared surfaces, then quickly
  cover with the other substrate to be bonded.
• On exposure to moisture, the freshly applied material will "skin-over". Any tooling should be
  completed before this skin forms. The surface is easily tooled with a spatula. The
  adhesive/sealant will be tack-free in less than 45 minutes.

Cure Time

• After skin formation, cure continues inward from the surface. In 24 hours (at room
  temperature and 50% relative humidity) DOWSIL™ 732 Multi-Purpose Sealant will cure to a
  depth of about 3 mm. Very deep sections, especially when access to atmospheric moisture
  is restricted will take longer to cure completely. Cure time is extended at lower humidity
  levels.
• Before handling and packaging bonded components, users are advised to wait a sufficiently
  long time to ensure that the integrity of the adhesive seal is not affected. This will depend on
  many factors and should be determined by the user for each specific application.

Compatibility

DOWSIL™ 732 Multi-Purpose Sealant releases a small amount of acetic acid during cure.
This may cause corrosion on some metallic parts or substrates, especially in direct contact
or when the cure is carried out in a totally enclosed configuration which would not allow cure
by-products to escape.

Handling Precautions

PRODUCT SAFETY INFORMATION REQUIRED FOR SAFE USE IS NOT INCLUDED IN
THIS DOCUMENT. BEFORE HANDLING, READ PRODUCT AND SAFETY DATA SHEETS
AND CONTAINER LABELS FOR SAFE USE, PHYSICAL AND HEALTH HAZARD
INFORMATION. THE SAFETY DATA SHEET IS AVAILABLE ON THE DOW WEBSITE AT

Usable Life and
Storage

Product should be stored at or below 32°C (90°F) in original, unopened containers.
As DOWSIL™ 732 Multi-Purpose Sealant cures by reaction with moisture in air, keep the
container tightly sealed when not in use. A plug of used material may form in the tip of a
tube or cartridge during storage. This is easily removed and does not affect the remaining
contents.

Limitations

This product is neither tested nor represented as suitable for medical or pharmaceutical
uses.
