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.
