Teflon® (PFA) Coat Glass - KLEARCOAT® Glass

KLEARCOAT® Glass is the observing material which NIHON KLINGAGE CO.,LTD.(N.K.G) was first developed in the world. It is produced by coating glass surface with TEFLON® PFA film by a special technique.

・Superior chemical resistance

Coated with TEFLON® PFA film, KLEARCOAT® Glass has outstanding resistance to those chemicals that corrode glass; caustic soda, hydrofluoric acid. (the only exception being molten alkali metals)
It is to be noted, however, that TEFLON® PFA film, like any other thermoplastics, allows a slight degree of permeation. Thicker coating is desirable if the purpose of its use requires non-corrosion.

・Superior non-sticking property

The surface coated with TEFLON® PFA film repels water, oil and almost all sticky substances. If such a substance should stick to it, it can be easily washed off.

・Remdrkable High Temperature Resistance

TEFLON® PFA has a better high temperature resistance than any other fluoroplastics. KLEARCOAT® GLASS can be continuously used at the temperature of 260℃. Heat cycle test (200℃ to 10℃) shows no observable signs such as peeling.

・High transparency

TEFLON® PFA film has a much higher transparency than any other fluoroplastics. The transparency of KLEARCOAT® GLASS is also excellent.

・High safety

If KLEARCOAT® GLASS should break caused by a high pressure, TEFLON® PFA coating prevents the fragments from scattering and moderates the gushing of fluid. This gives KLEARCOAT® GLASS the safety factor required of observing material for pressure vessels. The photographs right show a comparison when a 200g steel ball is dropped from the height of 3m.

It is possible for the KLEARCOAT glass to correspond to glass with various shapes of glass for the Liquid Level Gages, various circle glass for the sight glass and the others.
