The anaerobic composition VAK-5, grades A and B, is a colorless or yellowish liquid consisting of unsaturated oligoesters and catalysts. The manufacturer prepares the composition, prepares it in a plastic container and delivers it to the consumer in a ready-to-use form. The composition VAK-5 is intended for sealing micropores up to 0.1 mm in size in welds made by fusion welding on aluminum, magnesium and titanium alloys, as well as all types of steels. It is possible to introduce the composition VAK-5 under the overlap of welded joints made by resistance welding (spot and suture).
The temperature range of the composition from -50 to + 150 ° C for a long time and at 200 ° C for a short time. The composition VAK-5 grade A is intended for cold curing, and grade B is for hot curing. The composition of VAK-5 grades A and B ensures the performance of parts located in water, acetone, gasoline or aviation fuel. The curing of the VAK-5 grade A composition located in the pores or under the lap occurs at room temperature for 24 ... 48 hours, and grade B at a temperature of 140 ... 150 ° C for 0.5 ... 1 hour
