Electronics/PCB Manufacturing
The demands placed on today’s electronics can seem simply overwhelming. Consumers want devices to be smaller and faster. Engineers are requiring more flexibility, power, and durability from components within those devices. Protecting these delicate components demands innovative adhesives and coatings.
Novagard’s electronics grade silicones combine increased flexibility and high temperature resistance, allowing you more versatility in the design and assembly process. Our silicones reliably seal, bond, coat, gasket, and encapsulate to protect sensitive components and modules, increase the reliability, and extend the useful life of your product.

Why use alkoxy silicones in electronics?
- Non-corrosive
- Flexible and durable
- Environmental, UV, and chemical resistant
- Excellent physical properties
- Superior dielectric performance
- Primerless adhesion
- Thermal stability
- Preferred solution for shock absorption and vibration damping
- Easy to dispense

800-245 is a UV-cured conformal coating. Its moderately flowable viscosity easily coats complex geometries. Fully cured with UV light only (no secondary cure), this silicone offers moderate hardness with good electrical properties.
800-620 is a very soft, clear, encapsulant/gel, designed to maximize vibration damping. It is a low strength silicone with limited adhesion which reduces strain on delicate components. UV only cure.
800-255 is a first-generation pin connector sealant. Its oxime secondary moisture cure provides improved physical properties. The oxime moisture cure can present potential corrosion issues in enclosed applications.
800-260 is a first-generation conformal coating for printed circuit boards. While its oxime secondary moisture cure provides improved physical properties, it offers limited adhesion and can present potential corrosion issues in enclosed applications. This silicone is rated UL 746 E, V-1.
With viscosity of 50,000 cPs, 800-750 clings readily to components for staking and glob-top applications. This non-corrosive, single component silicone will cure to an extremely soft elastomer in seconds upon exposure to UV light, making it ideal for stress and strain relief as well as protection of delicate circuits. It has a secondary, neutral alkoxy moisture cure for enhanced adhesion and shadow cure.
800-230 offers design engineers a higher viscosity coating option, while still remaining flowable. 800-230 is an ideal staking material for securing small components against vibration. It is a UV only cure, providing limited adhesion.
800-235 is UV-cured, semi-flowable material. A UV-cure only silicone with limited adhesion, its higher viscosity makes it ideal for cured-in-place gaskets.
800-240 is a UV-cure only, semi flowable material similar to 800-235. 800-240 offers higher hardness and abrasion resistance with good elongation and electrical properties.
800-400 is a UV-only, fast-curing paste without adhesion. With nominal viscosity of 360,000 cPs, 800-400 consistently holds its shape even when dispensed into complex shapes.
800-610 is a low viscosity, pourable encapsulant. Its extremely low viscosity ensures the material flows easily around components for thorough wet-out. This is a UV cure with no secondary moisture cure, offering very low adhesion.
800-520FC is a UV-curable, silicone conformal coating, pottant, or sealant. This version of our original 800-520 coating utilizes Fast Cure technology to begin moisture cure of shadow areas in as little as 30 minutes, and provides a harder, more durable surface than our standard 800-520.
800-550 is a UV-curable, silicone coating, pottant, or sealant. With nominal viscosity of 5,500 cPs, 800-550 flows readily to surround the complex geometry of modern circuitry design. It has a secondary, neutral alkoxy moisture cure for enhanced adhesion and shadow cure. This non-corrosive, single component silicone will cure to a solid elastomer in seconds upon exposure to UV light.
800-505FC is a UV-curable, silicone conformal coating with a secondary, neutral alkoxy moisture cure for enhanced adhesion and shadow cure. It is UL 746E certified with a V-1 rating for flammability. Utilizing our Fast Cure technology, this secondary moisture cure begins immediately and develops full adhesion in hours.
