BIRKOSIT Dichtungskitt®

for maximum temperature and pressure resistance

Product number AIS B010

BIRKOSIT Description
BIRKOSIT Dichtungskitt® is a single-component, paste luting agent/sealing material for industrial use wherever conditions of temperature combined with pressure on smooth, plane sealing surfaces (butt joints) make extreme demands on the quality of the sealing compound.

This applies, in particular, to the sealing of metallic joints in:
steam and gas turbines, compressors, generators, expanders, pumps, flange joints, etc.

BIRKOSIT Temperature resistance
BIRKOSIT Dichtungskitt® withstands hot steam and air, hot and cold water, light fuel oils and lubricants, as well as crude oil and natural gas at temperatures of up to 900 °C.

BIRKOSIT Pressure resistance
The adhesion on sealing surfaces and butt joints is so high that a one hundred percent seal is guaranteed even for pressures up to 250 bar. The pressure resistance for flanges without sealing rings is guaranteed up to 450 bar, and even up to 550 bar for screw joints.

BIRKOSIT Service life
When used in accordance with instructions and with regular servicing as required for steam and gas turbines as well as for the application areas stated above, we guarantee a service life for use on machined sealing surfaces (butt joints) of 10 years.

BIRKOSIT Fields of Application
BIRKOSIT Dichtungskitt® is suitable for sealing all surface sizes. The surface quality of the sealing surfaces complies with milled/scraped surfaces with a finishing accuracy of
Ra = 0.8 µm to 1.2 µm. Sealing surface damage of ≤ 0.2 mm is compensated with BIRKOSIT Dichtungskitt®. For spot repairs on badly damaged areas of ≥ 0.2 mm to 1.0 mm, we recommend the products FILLING basic®, FILLING 1000® and FILLING 2000®.

BIRKOSIT Application
Apply the BIRKOSIT Dichtungskitt® to the dry sealing surfaces with a brush or putty knife on both sides. The layer thickness to be applied is 0.2 mm to 0.3 mm. The product can be subjected to workloads immediately! It does not cure, will not change its consistency even after several hours, and remains flexible and elastic. It is therefore also suitable for butt joint machining. The colour is reddish brown. Heating the tin to room temperature or adding a tenth part of standard linseed oil varnish (AIS B020) from our product range will improve the brushability.

BIRKOSIT Storage
Packed in 1 kg tins. If stored correctly, BIRKOSIT Dichtungskitt® has a storage life
of 5 years in the tin. Its properties are stable and it is flexible in use. Close the tin properly if only a part of the contents is going  to be used.
