Description

The kit is intended for quick local repair of chips, scratches, fastener removal spots and panels, when preparing paint in standard packaging is not justified. It is a plastic bottle with two internal compartments, where the base and the hardener are kept separately. The user removes the safety ring, presses the cap until it clicks, shakes the bottle for about a minute until uniform, and applies the material. A regular TUK holds 30–45 ml and a MiniTUK 8 to 20 ml depending on the mixing ratio, and MiniTUK is so far available only in the USA. It is applied with a natural dense-bristle brush or a very short-pile roller, and spraying is not recommended. The bottle can be resealed, but not tightly, so that pressure does not build up. The kit exists for a number of materials, in particular 454-4-1, 20P1-21, Varnish F80, Topcoat F70-A, XS420, FR2-55, Aerodur 2122 and 10P20-13.

How to choose

The kit is chosen by the scope of the repair. A TUK of 30–45 ml is enough for small areas on panels, and a MiniTUK of 8–20 ml is needed for the smallest damage. Surface preparation, pot life, film thickness and drying schedules are determined by the technical description of the specific material. TUK packaging is not always listed in the material specification, so the TDS and QPL are checked. For painting large areas, materials in standard packaging are used, for example Aerowave 3003 or Alumigrip 4200.
