Slide 3

Silicone Sealant Chemistry Silicone sealants consist of inorganic Siloxane (Si-O-Si-O-Si) polymers Basic formulation includes: polymer, filler, crosslinker, catalyst, adhesion promoter, pigment and plasticizer Silicone sealants may be one component or two components (fast cure) 3

Slide 4

Silicone Adhesives and Sealants from Dow Corning These products are versatile, durable and have exceptional performance characteristics This combination of properties has made them valued products for endless applications in the Industrial Assembly and Maintenance market; engineers have come to rely on Dow Corning Adhesives and Sealants to solve their most challenging problems Following are seven reasons why Dow Corning brand silicone sealants should be used 4

USING DOW CORNING BRAND SILICONE SEALANTS 5

Slide 6

1. Wide Service Temperature Range Dow Corning Adhesives and Sealants offer users exceptional thermal stability over a wide service temperature range Fully cured, these all-purpose materials can be used for extended periods at temperatures ranging from -85 to 450F (-65 to 232C), and there are some products that can be used for shorter periods up to 600F (315C) Glass transition temperatures are very low [e.g. -196F (-127C) compared to -100F (-73C)]; therefore, silicone sealants and adhesives remain flexible across a wide range of temperatures 6 -85F450F

Slide 7

2. Extremely Weather Resistant Dow Corning Silicone Adhesives and Sealants are virtually unaffected by weather including rain, sleet, snow, ultraviolet (UV) radiation, ozone and temperature extremes When compared with organic sealants and adhesives, these materials show excellent resistance to hardening, cracking, crumbling, drying out or becoming brittle with aging 7

Slide 8

3. Good Dielectric Properties When used for electrical/electronic applications, Dow Corning Silicone Adhesives and Sealants exhibit good dielectric properties over wide thermal cycling conditions. 8

Slide 9

4. Good Bond Strength Dow Corning Silicone Adhesives and Sealants are specially designed to provide good adhesion and bond strength to a variety of surfaces The materials have been developed to achieve excellent adhesion to glass, wood, silicone resin, vulcanized silicone rubber, natural and synthetic fiber, painted surfaces and many plastics and metals 9

Slide 10

5. Low Flammability In fire conditions, silicone adhesives and sealants are reluctant to burn; in fact, some grades are exceptionally flame retardant Even those types which eventually ignite have a low rate of heat release and low by-product toxicity Many products comply with UL-94 flammability standards such as UL-94 HB or UL-94 V-0 10

Slide 11

6. Chemically Stable Featuring good chemical stability, Dow Corning Silicone Adhesives and Sealants are ideal for use in applications exposed to harsh environments. 11

Slide 12

7. Environment Dow Corning is always striving to improve operations, working largely from the framework of the Responsible Care Pollution Prevention Code. 12 Responsible Care is a registered trademark of the American Chemistry Council, Inc.
