The dissipation of heat at high power densities, the protection of components and possible undercuts, the compensation of stresses, and much more require the highest standards for a permanently stable potting compound. Our Novasil® potting compounds can be optimally adapted to your applications and, among others, offer the following advantages:
Excellent plastic adhesion
Quick curing, even with thick layers for fast industrial production
Low viscosity for filling cavities without air bubbles
The flow behaviour of potting compounds is particularly relevant when working with them. The viscosity should be adapted to the conditions of the components. The self-levelling can, for example when using a low viscosity potting compounds for components with gaps and undercuts, avoid air pockets when filling and thus achieve the best-possible protection of the components.
In the case of high power densities in components and therefore any resulting hot spots with a high temperature load, sufficient thermal conductivity of the potting compounds used should be ensured. Our Novasil® potting compounds have different conductivities depending on the product and application and can therefore optimally dissipate the heat in the components so that the service life of the components is not negatively impacted by higher power densities.
High temperature resistance
Applications with high thermal loads require materials that withstand these loads without compromising their properties. By using high temperature resistant potting compounds, the installed components can be permanently functionally connected to each other and protected from high temperature fluctuations. Our high temperature resistant Novasil® potting compounds have different temperature resistances of up to 250°C so that we are sure to find the right product for your application.
Depending on the application, there are different requirements for the reactivity of the potting compounds used. Some potting compounds of our standard product range are therefore already available ex works with different pot lives so that the handling time can be perfectly adapted to the present application.
Potting compounds must be able to compensate for stresses that occur in components. That is why the mechanical properties of the potting compounds or the end state after curing play an important role when selecting the right product. Our product range has potting compounds with different shore A hardness grades to cover a wide range of applications.
Potting compounds must have self-extinguishing properties in many electronic applications. Fire tests, for example, define by category (V-0, V-1, V-2) a certain gradation over time in which the self-extinguishing must occur. Special additives and fillers in our Novasil® silicones improve the fire behaviour in order to fulfil the ULV criteria.
The adhesion is composed of a physical interaction, chemical bond and interlocking between two substrates. Our Novasil® potting compounds have a long-term stable adhesion and permanently protect components from environmental influences. They also have a good self-adhesion to many surfaces.
