FLUIDS
XIAMETER® Brand Polydimethylsiloxane (PDMS) Fluids offer very low viscosity (= 2 cSt). The polydimethylsiloxane fluids are categorized as volatile methylsiloxanes (VMS). In the United States, VMS fluids are exempt from regulation as volatile organic compounds (VOCs). Features and Benefits include;

• Excellent water repellency
• Good dielectric properties over a wide range of temperatures and frequencies
• Low glass transition (Tg) temperature
• Low surface tension
• Heat stability
• Oxidation resistance
• Very low vapor pressure
• High flash point
• Inert, nonreactive

Typical Uses

• Mechanical fluids
• Dielectric coolants
• Insulating and damping fluids for electrical and electronic equipment
• Release agents
• Foam control
• Surface active fluids
• Lubricants
• Ingredients for cosmetic and personal care formulations, polishes and specialty chemical products
• Plastics additives

Structure

XIAMETER polydimethylsiloxane fluids are linear, siloxane polymers that vary in viscosity from very low to ultrahigh.
From their siloxane backbone, PDMS fluids draw strength, stability and flexibility.
From their attached methyl groups, PDMS fluids gain inertness, lubricity, release properties and water repellency.

Composition
XIAMETER silicone emulsions are stable blends of silicone and water.
They typically include:
Silicone fluid or polymer (dispersed phase)
Water (continuous phase)
One or more surfactants
Stabilizing and performance-enhancing additives (such as thickeners, wetting agents, biocides, rust inhibitors and freeze-thaw protectors)

SILANES
Xiameter offers easy, reliable, top-quality silanes with a range of organic functionalities to meet different material fabrication polymerization and performance needs.
Functions
Coupling agent
Adhesion promoter
Hydrophobing and dispersing agent
Moisture scavenger
Polypropylene catalyst “donor”

Applications
Adhesives and sealants
Automobile tires
Fiberglass and composites
Mineral and filler treatment
Paints, inks and coatings
Plastics, polymerization and rubber
Water repellents and surface protection

Silane Advantages
XIAMETER silanes are extremely versatile and can be used in a variety of ways with carbon-based materials. They can help you improve:
Mechanical strength
Electrical properties
Moisture resistance
Adhesion
Compatibility
Dispersion of pigments, minerals and fillers
Polymer yield

Composition
Silanes are monomeric silicon compounds with four chemical groups attached to the silicon atom. These groups can be nonreactive, inorganically reactive, or organically reactive, in almost any combination.

XIAMETER SILICONE RUBBER
Xiameter silicone rubber, silicone elastomer and silicone rubber base offer reliability that is cost competitive. Products include both high consistency silicone rubber (HCR) and liquid silicone rubber (LSR) including silicone rubber compound, silicone rubber base and additives to meet specific processing and performance needs.
Functions and Benifits
Silicone rubber offers a range of functions and benefits:
Protection and insulation
Flexibility and resilience
Dynamic and static sealing
Improved tactile response
Noise and vibration control
Temperature resistance
Extended service life
Food contact
Inertness

Applications
The applications of silicone rubber include these industries:
High-voltage electrical distribution
Consumer
Bakeware
Infant care
General rubber fabrication
Automotive

Silicone Rubber Advantages
Longer service life in adverse environments
Unaffected by weather – rain, snow, humidity, ozone or damaging ultraviolet (UV) rays
Flexible and resilient across a wide temperature range
Good electrical insulating qualities that do not change significantly under exposure to severe environmental stress
Enhanced comfort and feel of consumer goods
Excellent sealing performance
Inert (no taste or smell) nature enables many food-contact options
A wide hardness range (from 10 to 80 Shore A)
A wide range of color choices (from transparent to brightly colored)
Excellent processability, more fabricating options, increased productivity

Composition
Silicone rubbers are inorganic synthetic elastomers made from a crosslinked silicon-based polymer reinforced with filler. They offer unique chemical and mechanical properties that organic elastomers just can’t match.

XIAMETER silicone rubbers are available to you in two forms to meet processing needs. Learn more about the chemistry and uses of these rubber forms:
High consistency silicone rubber (HCR)
-XIAMETER high consistency silicone rubber (HCR) materials are ready-to-use blends of silicone rubber base, fillers, modifiers, vulcanizing agents and pigments, heat cured to form elastomeric components
Liquid silicone rubber (LSR)
-XIAMETER liquid silicone rubber (LSR) compounds are two-part pumpable silicone materials that are mixed and rapidly heat-cured to form elastomeric components.

SEALANTS
Dow Xiameter offers cost competitive and reliable silicone sealants and sealant polymers to meet specific performance requirements.
Functions
Weatherproofing
Sealing
Bonding and adhering
Enhancing building aesthetics
Creating formed-in-place gaskets (FIPG)
Gap fillers

Applications
Do-it-yourself
Showers, baths and kitchens
Windows and doors
Vinyl siding and trim
Roofing and flashing
Perimeter sealing
Professional building trades
Low-rise/residential construction
General sealing and caulking applications

Silicone Sealant Advantages
Silicone sealants outperform and outlast organic weatherproofing sealants
Silicone sealants have greater UV stability, and temperature and weather resistance than organic sealants
Silicone sealants are inherently waterproof
Silicone sealants remain flexible over a wide temperature range and are easy to apply in cold weather
Silicone sealants last longer and need to be replaced less often than many organic sealants, which reduces lifetime costs and contributes to sustainability

Composition
Dow Corning XIAMETER silicone sealants are mixtures of silicone polymers, fillers and crosslinkers. These one-part compounds are room temperature vulcanizing (RTV), meaning they cure at room temperature.

Types of Sealants
Acetoxy cure silicone sealants
Alkoxy cure silicone sealants
Oxime cure silicone sealants
Silicone sealant polymers
