Aniline leather degreaser Kit A3.dr - features Degreaser-2.2 with a pH value of 2.2 and aniline Topcoat-79G. Degreaser-2.2 is a high viscosity aqueous formulated leather degreaser; for degreasing leather of penetrated sweat, oil and grease stains from skin and hair contact. Topcoat-79G is a gloss topcoat for aniline leathers. It’s an aqueous fine particular size urethane resin emulsion topcoat to protect aniline dyestuff with excellent toughness and flexibility. In most cases the damaged topcoat is camouflaged by the greasy contamination and becomes apparent once the grease is removed. A complete restoration process would involve removing the entire deteriorating topcoat with the help of optional Stripper-2.3, leather Eraser-4; and rejuvenate the leather structure for softness to prevent cracks prior to topcoat refinishing it.

■ Aniline Leather Degreasing System
Degreasing process involves two steps; first is the sufficient penetration of the degreaser to react with the grease and second is to cause a wicking action to bring out the grease. This process may be repeated depending on the depth of grease penetration. An advance technique is to cling wrapped the degreaser to control evaporation for a more effective dwell time.
Instructions
1st Phase Degreasing:
1] Warm up Degreaser-2.2 and shake very well until it turns to an opaque gel.
2] Apply direct and agitate with horsehair Brush-1 and/or Eraser-4 and towel extract until it shows clean.
3] Penetrated stains may require a deeper penetration, a dwell time of 5 to 30 minutes or before it dries for chemical reaction to occur, follows with towel extraction. Severe cases can be saturated and cling wrapped to control evaporation for a longer overnight dwell.
4] Suspended residue is to be rinse with Rinse-3.0 and towel extract until it shows clean.
5] Let natural dry for suspended particulates to wicks up, erase with Eraser-4 and inspect for satisfaction, otherwise repeat as necessary.
2nd Phase Stripping:
When topcoat damages are revealed, it is recommended that the entire panel is stripped to ensure an even appearance for topcoat refinishing. This is best done after the degreasing process.
1] Apply optional Stripper-2.3, scrub with leather Eraser-4 and towel extract to remove the topcoat damaged panel entirely.
2] Optional is use leather Razor-60 for shaving off topcoat, smoothen with 1000 – 1500 grit wet/dry sanding disc in conjunction with Rinse-3.0 with repeat towel extraction.
3] Spray Rinse-3.0 to remove topcoat residues to a squeaky clean.
3rd Phase Hydrating:
1] Spray Hydrator-3.3 with help of foam brush to penetrate the leather for an even appearance.
2] To further activate dormant dyestuff to resurface, the entire seat is wrapped with clear cling wrapper to control evaporation for an overnight dwell for an even appearance. The relaxed leather structure allows the creases and wrinkles to be further worked out for better appearance.
3] Towel extract until towel shows clean prior to immediate fatliquoring.
4th Phase Fatliquoring:
1] Fatliquor-5.0 follows the same procedure as the Hydrator-3.3, with in between drying application as moisture evaporates until it’s saturated.
2] The fully saturated leather is left for slow natural drying for extra softness.
5th Phase Dry Preparation:
1] Inspect for complete removal of existing topcoat, texture roughness is to be smoothen with sanding (1000 – 1500 grit).
2] The leather surface is work over free of residues with Eraser-4 to an even appearance.
6th Phase Topcoat Application:
1] First coating is applied by lint free towel or foam brush with optional 1500 grit fine sanding in between dry coating for smoothness.
2] Airbrushing is optional for a professional result with in between fine sanding to achieve the desired smooth feel.
7th Phase Non-stick Rub Resistant Protection:
1] Spray Leather Scent-B, spread with lint free towel or foam brush and it’s ready to use when dry.
Topcoat Refinishing System
The objective of the topcoat is to impart a film forming coating that provides abrasion and stain resistance to the aniline leather crust. It is this Topcoat-79G that decides its desired luster. Without this topcoat, the aniline leather crust would be: a) poor in aesthetics such as appearance and feel; b) poor physical properties such as wet rub, sweat resistant and scuff resistant; c) poor in ageing properties such as soil resistant and wet cleaning resistant. To improve appearance for faded leathers, reactivating the dormant dyestuff to resurface with Hydrator-3.3 is often an option worth trying before resorting to dye refinishing. Topcoat will enhance the beauty of the leather crust, thus it’s a good practice to test out a little line along the seam on how the appearance will turn out. It is after the appearance test out that the need to apply new dyestuff is decided.
Instructions:
1] It is recommended that the leather surface is free from foreign soiling prior to topcoat touch-up or refinishing.
2] Touch-up is applicable where a healthy topcoat is physically damaged by working in conjunction with fine sanding in between dry coats for an even appearance.
3] Used, worn and deteriorated topcoat damages are recommended to be stripped clean of the entire panel prior to topcoat refinishing.
4] Sanding is recommended progressively in between coatings rather than on the leather crust itself, as the crust becomes coarser the more it is sanded.
5] Test out a little line along the seam with a cotton swab to see how much the color can be bounced back.
6] Option to increase the color intensity is to use matching transparent Aniline Dye-21. It is best done by airbrushing as color intensity is increase by layers. Do not over do it as the color intensity will be magnified with topcoat.
7] First topcoat is recommended to be applied with lint-free towel or by brushing for better anchorage to the leather crust.
8] Subsequent coating can be airbrush to avoid streaks to the desired appearance.
9] When dry with satisfaction, non-stick rub resistant protects the seats with leather Scent-B.

■ Aniline Leather Dye Transfer Stain Removal System
Common dye stains are from blue jeans, newsprint and dyed goods. Most of these leathers are absorbent and in most cases the suspended stains is easily reabsorbed into the leather than can be towel extracted entirely. Complete removal of these reabsorbed residual dyes may require a hydrating process to disperse and wicks them. The technique is to place absorbent tissue paper as an extension of the leather surface to trap these fugitive dyes in the wicking process. Fatliquoring to soften and strengthen the leather after complete stain removal is highly recommended. Topcoat refinishing is an option found in Kit A3.r. Note: Stains that have been attempted by unknown products may be set tougher to remove. It’s also recommended to use tap water wet finger test for tackiness or sliminess. If it is, acidifying it with Acidifier-2.0 found in Kit A3.t to return the leather to a squeaky feel is highly recommended prior to Prep-4.4 application.

■ Aniline Leather Leather Rejuvenating System
Rejuvenating system is the process of restoring the original fatliquor diminished through aging and cleaning to return to its characteristic suppleness. Leathers, when wet and then dry again, have the tendency for the fibrils to becomes stick together - known as the Van der Waals or London force phenomenon. This results in stiffness and when flexed, may lead to premature cracks, as often seen on neglected leathers. It is recommended to hydrate these exposed leather structure and replenish the diminished fatliquor while it is still damp. When dry thereafter, the leather fibrils will be well separated and lubricated to slide over one another smoothly during practical usage.
