DOWSIL™

DOWSIL™ Adhesives and Sealants

Many components in the automotive, electronics, electrical, and engineering industries require sealing or gaskets to protect against dust and moisture or to prevent gas and liquid leakage.

• Typical characteristics of DOWSIL™ sealants are:
• Excellent resistance to prolonged compression, even at extreme temperatures
• Good adhesion to all substrates
• Long-term stability over a wide temperature range ( -60°C to > 200°)
• Resistance to oil, water, coolants, detergents and many other chemicals
• Resistance to different climatic factors (UV, ozone, oxidation)
• Excellent electrical properties
• Low flammability and toxicity near heat sources
• They do not require solvents during the process.

DOWSIL™ Electronic Protection Products

DOWSIL™ has always been a leading global authority on silicones. The Electronics Division is entirely dedicated to the development of products and technologies dedicated to the world of electronics, starting from semiconductor production to the assembly stage.
In electronics, silicones are preferred because of the following characteristics: excellent dielectric properties, excellent weathering resistance, stability over a wide temperature range, good adhesion on a wide variety of substrates, lower stresses on components, resistance to ultraviolet rays and chemicals.The products can be used for applications in modules, connectors, sensors, PCBs and many more.

The DOWSIL™ range includes:

• Silicone adhesives and sealants, designed for clamping components, sealing joints, and protecting delicate components
• Conformal Silicone Coatings for protecting printed circuit boards from moisture, contaminants, mechanical abrasion, thereby preventing short circuits and increasing board life. Products conform to the circuit by protecting it for a long time
• Silicone-based encapsulants and gels designed to electrically insulate and protect electronic components from harsh chemicals, mechanical stress, and external tampering. Gels are particularly suitable for sensitive components
• Thermoconductors developed to meet the increasing needs to dissipate heat in components that are becoming smaller, more powerful, and faster. Dowsil thermal conductives are available both in ‘wet’ form, that is, to be cured, and in film or mat form.

Lighting DOWSIL™

In Lighting, DOWSIL™ is entirely dedicated to the development of products and technologies specifically dedicated to semiconductor manufacturing, LED packaging, molding of optics, to the assembly stage of lamps and luminaires. The DOWSIL™ range includes:

• Printable optically transparent silicones for manufacturing optics
  Optical encapsulants that have an optimized refractive index to maximize luminous flux
• Gels and thermal encapsulants that ensure reliable performance of LED modules even under the harshest conditions, with the best sealing. They protect delicate system components, including connectors, circuits and power supplies, by dissipating damaging heat and absorbing the noise component
• Thermally conductive thermal interface materials developed to meet the increasing needs for heat dissipation in components that are becoming smaller, more powerful, and faster
• Adhesives and sealants to form excellent joints and seals on a wide range of substrates commonly used in LED applications
• Conformal coatings to protect the delicate electronics connected to LEDs from moisture, thermal stress and critical weather conditions.

Photovoltaic DOWSIL™

DOWSIL™ silicone products improve the efficiency, durability and performance of solar panels and photovoltaic devices, making them more technically and economically viable.
While solar cells are made of silicon, silicones are instead used during module assembly and installation as encapsulating and insulating coatings, adhesives, and sealants.

The most popular applications in the photovoltaic industry are:

• Coating and encapsulation of cells
• Encapsulation and bonding of junction-boxes
• Bonding and sealing of frames, rails and supports
• Because they can withstand the relentless rays of the sun year after year, silicones are ideal and unsurpassed materials for applications on both solar and photovoltaic (PV) panels.
