SEALING, BONDING AND POTTINGLighting industry

Whereas elastic bonding has been well established for decades in other fields of industry, such as in the domestic appliances industry, adhesives and sealants in the lighting industry has only really come into their own with the introduction of LED technology. The possibility to permanently install the lamp without the need to change the bulb opens up to designers a completely new way of designing things - delighting them all the way! Quality from the OTTO brand – that's what makes the difference.

Bonding, sealing and potting lights

Similar to use in the field of architecture, elastic bonding in the field of electronics enables smooth, consistent, flat surfaces in the design of lamps and spotlights, since visually disturbing screws and fasteners are now a thing of the past.

For the manufacture of interior lighting and exterior lighting alike, OTTO offers a wide range of RTV-1 and RTV-2 silicone adhesives developed especially for the lighting industry.

Not only that - OTTO also offers the right elastic adhesives for the series bonding of lamps and car headlights in the automotive industry.

SEALING, BONDING, POTTING AND COATINGCommunication technology and electronics

Whereas, in most other parts of industry, bonding and sealing are the centre of attention, the potting and coating of components play the leading role in the field of communication technology and electronics. Transformers, cables, plugs, condensers, generators, circuit boards - OTTO offers the small problem solver with the big advantages for all these. Quality from the OTTO brand – that's what makes the difference.

Bonding, sealing, potting and coating

In the world of electrical engineering, small components are generally cast with high-strength brittle material such as epoxides and polyurethanes. On the other hand, the industry is increasingly using soft, elastic materials such as silicones for larger components subject to strong vibrations or temperature fluctuations. In addition to the excellent electrical insulation properties, these potting compounds need fire retardant properties as well as high thermal conductivity. The vibration-damping properties and the excellent resistance to temperature fluctuations, which range from between -40°C and 150°C in the case of most silicones, are particularly impressive in the electronic components which are built into the engine compartment.

Coating protects printed circuit boards

The coating and the application of protective varnishing to printed circuit boards in the field of electronics and communication technology protect them from dust, light and aggressive chemicals. The mechanical and thermal stressability as well as the insulation strength of the circuit boards can be further improved by a coating.

Adapted in lines with the customer's requirements

In the field of potting compounds and elastic coatings, OTTO offers the electronics industry a selected range of 1-component and 2-component potting compounds. Like with adhesives and sealants, the properties of these potting / coating compounds can be adapted to meet the requirements of the customer if needed.
