BIW provides a clear view – HighQSil LFO “Low Fogging” Silicone

The newly developed BIW Silicone series HighQSil LFO reduces streaking on glass surfaces. The insulating material thus reduces an aesthetic annoyance and can also provide greater safety on the road.

BIW can help - HighQSil LFO

When non-volatile components made of silicone de-gas and meet cooler surfaces, this can result in unwanted fogging. This is referred to as the “fogging effect,” a streaking that shows up as a whitish coating on the glass surface. The phenomenon occurs, for example, with window façades of buildings, windscreens or aeroplane windows.

Streaking is not just an aesthetic problem; it constitutes a considerable safety risk if visibility is impaired, for example while traveling in a car. Therefore, it makes sense to use low-gassing insulating materials that prevent fogging, not just in building construction, but also in automobile and aeroplane design.

BIW has now developed the HighQSil LFO material series, which sharply reduces the fogging effect. The silicone materials, according to EDAG testing in conformity with DIN 75201, have a gravimetric fogging value of < 0.1 mg per 10 g of material and a reflectivity of > 98.5%. There is little or no streaking. The low-gassing silicone is available in the hardness range from Shore A 50 to 80.

Your BIW team will be glad to entertain any other questions you may have.
