The sealant Vitap NT

The sealant VITAP-NT - characteristics, use of

The sealant VITAP-NT is a three-component sealant, pinkish-beige color after curing, consisting of the main paste, curing paste and a vulcanization accelerator. In the delivery state the components of the sealant are in separate containers in the ratio ready to use. VITAP-NT used in civil and military aircraft industry for surface and nutricional sealing bolted and riveted joints, glazing element devices operating in the environment of fuel type TS-1 at temperatures from - 60 to + 130 °C. the Sealant Vitap-NT allowed to use in different climatic conditions, and the use of sublayers usilivayushchikh adhesion of the sealant is not required. VITAP-NT after mixing the components retains thixotropy, has excellent adhesion to metals and organic glass.

Method of application Vitap-NT
The sealant Vitap-NT is applied with a spatula, syringe and, when diluted with solvent - brush. As the solvent used R-5 (40 M.). The complete curing process, when the passport physico-mechanical and adhesive properties, expires after 7 days at room temperature. Incomplete curing process, wherein the sealant becomes elastic properties, but results have not yet stabilized carried out 72 hours. The surface to be sealed before applying the sealer thoroughly cleaned from dust, dirt, chips and other foreign debris and litter through the hair or metal brushes or rags. To remove moisture, traces of mineral oils and other fatty stains and dirt on the surface is degreased with benzene brands of BD-1 ("Shoe"), applied on a clean cloth or rag, and wiped dry with a clean dry cloth. Then, after 5-10 min, produce secondary degreasing in the same order or wiping with acetone aged 10-15 min until the moment of applying the sealant to the surface. The degreasing zone shall overlap the part where you want the seal, not less than 10%. The homogeneity of the prepared sealant, no air inclusions and unmixed particles of ingredients determine the required technological and operational properties of the sealant.

Warranty period of storage of basic paste - 6 months., curing - 3 months. The basic pasta is packaged in metal containers, curing the paste - in a plastic jar, a vulcanization accelerator in plastic bags. Next, the sealant Vixent-1-88. Specifications, operating instructions.
