DESCRIPTION

Dow Corning

brandone-part

moisture cure adhesivesare generally

cured at room temperature and in an

environment of 30 to 80 percent

relative humidity eliminating the need

for curing ovens and the associated

costs of energy and capital. Greater

than 90 percent of full physical

properties should be attained within 24

to 72 hours and varies according to

product. Faster manufacturing

throughput can be achieved since the

adhesive and component can be

handled in much shorter times of

about 10 to 120 minutes, depending on

the adhesive selected and the amount

applied. These adhesives are not

typically used in highly confined

spaces or where a deep section cure is

required as they generally cure from

the exposed surface inward at a rate of

0.25 inch per seven days. Cure

progresses from the outer exposed

surface and is dependent on the

moisture in the air. Working time is

generally a few minutes to an hour for

these products until a surface skin

begins to form. Mild heat below 60°C

(140°F) may be used to increase

through-put by accelerating the cure.

adhesives retain their original physical

and electrical properties over a broad

range of operating conditions which

enhance the reliability of and service

life of electronic stable

options of these adhesives offer

benefits for a variety of electronics

needs from increasing component

safety and reliability, reducing total

cost or increasing the performance

envelope of devices or modules.

USABLE LIFE AND

STORAGE

For best results, Dow CorningRTV

adhesives should be stored at or below

the storage temperaturelisted on the

product label. Special precautions

must be taken to prevent moisture

from contacting these materials.

Containers should be kept tightly

closed with head or air space

minimized. Partially filled containers

should be purged with dry air or other

gases, such as nitrogen. The product

should be stored in its original

packaging with the cover tightly

attached to avoid any contamination.

Store in accordance with any special

instructions listed on the product label.

The product should be used by its Use

Before date as indicated on the

product label.

contaminants such as mold release

agents, oils, greases and oxide films.

ADHESION

Dow Corningsilicone adhesives are

specially formulated to provide

unprimed adhesion to many reactive

metals, ceramics and glass, as well as

to selected laminates, resins and

plastics. However, good adhesion

cannot be expected on non-reactive

metal substrates or non-reactive

plastic surfaces such as Teflon

®

,

polyethylene or polypropylene.

Special surface treatments such as

chemical etching or plasma treatment

can sometimes provide a reactive

surface and promote adhesion to these

types of substrates. Dow Corning

®

brand Primers can be used to increase

the chemical activity on difficult

substrates. Poor adhesion may be

experienced on plastic or rubber

substrates that are highly plasticized,

because the mobile plasticizers act as

release agents. Small-scale laboratory

evaluation of all substrates is

recommended before production trials

are made.

PREPARING SURFACES

All surfaces should be thoroughly

cleaned and/or degreased with

Dow Corning

®

brand OS Fluids,

naphtha, mineral spirits, methyl ethyl

ketone (MEK) or other suitable

solvent. Solvents such as acetone or

isopropyl alcohol (IPA) donot tend to

remove oils well, and any oils

remaining on the surface may interfere

with adhesion. Light surface abrasion

is recommended whenever possible,

because it promotes good cleaning and

increases the surface area for bonding.

A final surface wipe with acetone or

IPA is also useful. Some cleaning

techniques may provide better results

than others; users should determine

the best techniques for their particular

applications.

USEFUL TEMPERATURE

RANGES

For most uses, silicone adhesives

should be operational over a

temperature range of -45 to 200°C

(-49 to 392°F) for long periods of

time. However, at both the low-and

hightemperature ends of the

spectrum, behavior of the materials

and performance in particular

applications can become more

complex and require additional

considerations. For low-temperature

performance, thermal cycling to

conditions such as -55°C(-67°F) may

be possible, but performance should

be verifiedfor your parts or

s that may influence

performance are configuration and

stress sensitivity of components,

cooling rates and hold times, and prior

temperature history. At the high-

temperature end, the durability of the

cured silicone elastomer is time and

temperature dependent. As expected,

the higher the temperature, the shorter

SUBSTRATE TESTING

Due to the wide variety of substrate

types and differences insubstrate

surface conditions, general statements

on adhesion and bond strength are

impossible. To ensure maximum bond

strength on a particular substrate,

cohesive failure of the product in a lap

shear or similar test is needed to

ensure compatibility of the adhesive

with the substrate being considered.

Also, this test can be used to

determine minimum cure time or to

detect the presence of surface
