Putty

Kitt is the name for an adhesive and sealant.

Historically, the term was "glue " (also Kütt ) generally used for very different types of binders such as glues, pastes and mortars. Today it is often used as a composite with the materials to be joined, such as putty or putty.

Conventional cement is a well known since about 1700 sealant that around 85 percent of whiting (calcium carbonate) and 15 per cent of linseed oil varnish is - which is why he is also known as Linseed Oil. It is available as supple malleable paste in the trade. From the constituents of whiting and boiled linseed oil putty can also be produced even. Mainly used as putty seal upon insertion of windows, but can also, like wood filler be used for repairing damaged areas of wood components. Putty hardens in the air by oxidation of the linseed oil over several years and is brittle. He can no longer follow the relative movements between windows and glass and crumbling. Thus, the window is leaking and cementing must be repaired or replaced. Age embrittled putty can be the gentlest soften by brief irradiation with short- wave infrared radiation and then lightly scrape. Such lamps are offered commercially.

Currently insulating glass panes are mainly glassified with fully synthetic sealants. Classic linseed oil putty is indeed rarely used in industrial production, but is still used in traditional crafts for glazing, for waterproofing and repair work, especially in single-glazed windows in wood, metal and concrete frames, as well as composite and casement windows with wooden wings. Classic linseed oil putty can be painted unlike silicone, with traditional linseed oil paint after only one week. However, If you want to paint over it with synthetic resin paint, so he must first harden up to 4-6 weeks.

Modern putty can also be produced as intumescent material which is used in the foreclosure of electrical and mechanical penetrations in structures to achieve a specific fire resistance class.
