Freeze spray

KONTAKT CHEMIE Freeze 75 Super

Description:

Cooling agent, mixture of 1,1,1,2 tetrafluoroethane and difluoroethane

General properties and applications:

KONTAKT CHEMIE Freeze 75 Super is a mixture of fluorocarbons liquified under pressure.

The fluid vaporises very quickly and, in doing so, extracts heat of vaporisation from the

environment. As a result, the sprayed surface cools down considerably. Freeze 75 Super

volatilises totally; conventional constructional materials are not attacked. The refrigerant

mixture present does not have an ignition range with air. KONTAKT CHEMIE Freeze 75

Super is used therefore in particular in areas where it is essential to eliminate dangers posed

by the use of flammable gases and liquids.

A typical application for the product is the location of thermal faults in electrical equipment. It

is also suitable for the freeze shrinking of small components, for the removal of sticky

contaminations from textiles, for the stiffening of "rubbery" materials and for the handling of

histological specimens.

KONTAKT CHEMIE Freeze 75 Super contains no CFC's.

Application instructions:

KONTAKT CHEMIE Freeze 75 Super is used for the location of thermal faults in electrical

equipment. For this purpose the piece of equipment being tested is started up. If a fairly long

period of operation is expected before faults occur, the warm-up phase can be accelerated

using a hair drier. After the equipment malfunctions, suspect components are purposefully

sprayed with Freeze 75 Super and changes in the function of the equipment are observed. A

faulty component can quickly be located by this method.

KONTAKT CHEMIE Freeze 75 Super can be used for the shrinkage of small components. In

trials it was possible, for example, to fit ball bearings of 30 mm outside diameter into

transverse press fits. In moist air an ice coating forms on the surface on cooling. This ice

coating is washed off before fitting, for example, using KONTAKT CHEMIE KONTAKT WL or

another water-miscible solvent.

Sticky substances such as chewing gum become hard and friable when sprayed with

KONTAKT CHEMIE Freeze 75 Super. They can then be teased out of fabrics without

difficulty. Release papers on self-adhesive foils can readily be removed after brief spraying.

Freezing with KONTAKT CHEMIE Freeze 75 Super is also suitable for the handling of soft

rubber or histological sections.

Components can be immersed in a small supply of refrigerant. Well-insulated small beakers

of thick-walled Styropor® (polystyrene) are suitable as containers. The latter can be made,

for example, from the used safety packaging of glass bottles.

When soldering with electric soldering irons, sensitive components can be protected from

overheating.

KONTAKT CHEMIE Freeze 75 Super does not attack ordinary materials. However, parts

which have a sensitive reaction to rapid changes of temperature must not be treated with the

product. Freeze 75 Super volatilises completely. In a high humidity, dew is deposited which

freezes into ice and then forms a whitish coating which disappears of its own accord.

Using the procedures described, KONTAKT CHEMIE Freeze 75 Super is absolutely safe

from a health standpoint. The freezing agent must not however be sprayed into flames. If it

were, it would decompose into very toxic substances.

The product can cause frostbite to the skin. It is not suitable therefore for the treatment of

sporting injuries.
