HOW TO USE

Substrate preparation

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.

• One-component adhesive/sealant

• Cures at room temperature when

exposed to moisture in the air

• Acetoxy cure system

• Non-sag, paste consistency

• Easy to apply

• Cures to a tough, flexible rubber

• Good adhesion to many substrates

• Stable and flexible from

-60ºC (-76ºF) to +180ºC (356ºF),

with short peaks up to +205ºC

(401ºF)

• Black version: stable and flexible

from -60ºC (-76ºF) to +205ºC

(401ºF), with short peaks up to

+230ºC (446ºF)

• Excellent dielectric properties

• Complies with MIL-A-46106

• Complies with FDA 177.2600

• Available in white, black or clear

However, for maximum adhesion, the use of DOW CORNING® 1200 OS Primer is recommended. After solvent cleaning, a thin coat of DOW CORNING 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 DOW CORNING 732 MultiPurpose Sealant to one of the prepared surfaces, then quickly cover with the other substrate to be bonded.
