Lighting

By forming durable, low-stress elastomers, Mascherpa silicone adhesives and sealants enable excellent bonding and sealing between a variety of common LED lighting materials. This increases design flexibility and ensures reliable long-term performance at temperatures up to 150°C. These solvent-free materials, cure at room temperature, this greatly simplifies processing and due to their low volatility, helps your product maintain its light output throughout its lifetime.

The use of an encapsulating resin to protect LEDs has become increasingly common in recent years. The choice of resin depends on several factors; viscosity, service life and gelation time, as well as hardness, density, and operating temperature of the hardened resin. When directly protecting the LED, there are a number of essential factors; fundamental among them is the transparency of the material applied to ensure maximum utilization of the light emitted by the LED. In addition, any changes that may occur over the life of the LED should also be considered.

The delicate electronic components of your project must be protected from moisture and physical stress. Mascherpa’s silicone conformal coatings can provide this protection, as well as excellent insulation from shock and short circuits. They are available in different viscosities and curing chemistries.

Protection and performance go hand in hand; Mascherpa encapsulants help balance both. In addition to moisture resistance, they absorb the stresses of thermal cycles, protecting sensitive components. Their high transmittance and thermal stability help your project maintain light quality for a longer period of time, while their unique chemistry offers minimal yellowing and degradation.
With a selection of curing, viscosity and hardness profiles, new design options can be explored in a variety of applications. Mascherpa encapsulants also expand processing options, from dispensing materials to the ability to make overmolded lenses.

Nothing shortens the life of LED lighting more than heat–and LEDs generate a lot of it. By designing with silicone thermal interface materials, you have more options for heat management.
The thermal stability of silicones provides consistent and long-lasting thermal conductivity, even at temperatures at which traditional materials might begin to degrade.

Thermal adhesives form thermally stable bonds with most LED PCBs and heat sink substrates and offer excellent thermal conductivity. Their low volatility does not adversely affect components or light output. In addition, their sealing and adhesive qualities make it possible to minimize the number of components and optimize the production process.

Mascherpa’s moldable silicone optics offer an unprecedented level of design freedom. Versatile and moldable, these materials allow more complex designs to be explored, often simplifying the manufacturing process.
In addition, they can increase the long-term performance of your project beyond the capabilities of traditional optical materials. Not only do they offer excellent optical properties, but they are also more resistant to impact damage and degradation from UV, heat and extreme environmental conditions. In this way, they can help provide greater lumen density while remaining stable over time.
With moldable silicone optics, new design possibilities can be explored in complex applications such as automotive lighting, outdoor displays, general, professional and consumer lighting.
