Chambers with Controlled Atmosphere Systems must be thoroughly gastight. In order to achieve the gas tightness of a chamber all the joints in the chamber must be covered with high quality gas sealants. OXYCAT offers a high quality solution for CA chambers gastightness – OXY GT Materials. The most important and main product of gas tightness material is GT COAT coating. If this coating is applied correctly and in sufficient quantities without leaving any air gaps, it can serve for decades without any maintenance or repair.


OXY GT-COAT™ is a ready-to-use, elastomeric main coating material for gas sealing. It is an acrylic dispersion-based, water-based, one-component, ready-to-use sealant for walls and ceilings. This coating has been specially developed for gas-tight finishing of CA Chambers.


It is generally used in gas-tight cold rooms, which are suitable for the CA technology applied for long-term storage of fruits and vegetables, server rooms, high altitude system rooms, O2Low organic fumigation rooms, ripening rooms and other places that require
professional high level gas tightness barrier. It can be used on any surface, coated steel, sandwich panels and concrete, etc., indoors, with horizontal and vertical angles of application.



OXY GT COAT stands out as a unique leader in the field of sealing. This tremendous product is the pioneer of gas tightness and plays a critical role, especially in the chambers with Controlled Atmosphere. Thanks to its ability to perfectly seal the joints between panels with a unique gas barrier feature, OXY GT COAT offers superior performance compared to other coating products in the controlled atmosphere sector.

First of all, its special formula is designed to deliver excellent performance of %100 gas tightness for years to come. OXY GT COAT coating provides not only gas tightnes but also a gas barrier between the atmosphere inside the chamber and the air outside. This maintains the required gas ratio parameters in the chamber and reduces the work load on the system.

It is also a perfect solution for dealing with problems such as mold and mildew in cold stores. Mold formation may be observed in the cold stores due to cross contamination coming from the orchards or due to condensation of cooling application problems. Our special formula of the coating doesn’t let any kind of fungi or mold growth over the surfaces it is applied on.

When the temperature outside changes from hot to cold and vice versa, the ground the facility is built on may move and cause openings in the joint places of the panel construction. However, these changes are neutralized by OXY GT COAT’s flexible and strong adhesive gas-tight properties.

Moreover, in the region where the facility is located, earthquakes severe enough to dislodge the grounds may lead to the panels slipping during the ground settlement. When these situations occur, OXY GT COAT prevents the panels from splitting thanks to its flexible and strong adhesive gas-tight feature.
