1: What is Aniline Leather Degreasing?
1.1: Degreasing or removing surface and penetrated grease is essential for good topcoat bonding, just like any other refinishing work based on the same principle.
1.2: However, amphoteric protein leather material is especially pH-sensitive, leather pH value of 3 to 5 should be maintained at all times during the degreasing process.
1.3: A high pH value product bleeds the dyestuff and displaces it with blotchiness.
1.4: A high pH or alkalinity degreaser denatures the leather when the tanning agents leach out resulting in tackiness and in the worst case sliminess.
1.5: All degreasing processes will also dry up the original fatliquor to a degree and a high pH value does more harm in drying up the leather.
1.6: When degreasing existing cracks or dried leathers it is recommended that hydrating it with Hydrator 3.3 before Fatliquor 5.0 first to top-up the fatliquor content before degreasing.
1.7: Preconditioning helps prevent over-drying of the leather during the degreasing process that may accentuate or magnify existing cracks.
2: How to Degrease Aniline Leather?
2.1: Aniline leather is degreased with Degreaser 2.2, pH balancing rinse with Acidifier 2.0.
2.2: It is highly recommend that the degreased and pH balanced area is clean over with Cleaner 3.8 and rinse with Rinse 3.0 to have an overall even darkening appearance without a dry line or edge.
2.3: Degreaser 2.2 is a dual-purpose formulation with a pH value of 2.2 to safely degrease the leather surface and penetrated soiling while charging the protein fiber ionic positive (+ve) for an increased hydrogen bonding with the other ionic negative (-ve) leather constituents like the tanning agents, dyestuff and fatliquor.
2.4: Acidifier 2.0 is a water-based acidifier with a pH value of 2.0 that works in sync with Degreaser 2.2 to rinse and pH-balance by charging the leather protein fiber ionic positive (+ve) to increase the attraction between the ionic negative (-ve) leather constituent like the tanning agent, dyestuff, and fatliquor from tackiness, bleeding, and stiffness.
2.5: Clean 3.8 is an all-purpose leather-safe mild anionic universal cleaner particularly effective in emulsifying oily soils and suspending particulates without the potential side effects like rings and browning on sensitive leather, suede, Vachetta, and Nubuck. A holistic cleaning system is recommended with Rinse 3.0 to return the leather to its pH chemistry integrity.
2.6: Rinse 3.0 is a pH-3.0 value rinse to remove suspended soiling that also functions as a pH balancer, it is used for an overall rinse after Acidifier 2.0 to bring the leather closer to its pH neutral.
3: How to work with Degreaser 2.2, Acidifier 2.0, Clean 3.8, and Rinse 3.0 system?
3.1: Degreaser 2.2 is applied after about 5min of swirling with final shaking when coagulating build up.
3.2: The gel degreaser is for easy control for saturating sufficiently where apparent body contact soiling is evident and feather out to less body contact soiling areas, with an overall darkening appearance.
3.3: Eraser 4 is used for better traction without the risk of scratching the finishes.
3.4: Eraser 4 has the potential of removing deteriorating topcoat that need refinishing.
3.5: Leather Brush 1 is used for stitching rows, welting, groves, creases, and wrinkles.
3.6: Emulsified and suspended soiling are extracted with a dry towel until new folding sides shows clean.
3.7: Acidifier 2.0 is applied, brushed, and erased followed by towel extraction changing folding sides until the towel shows clean.
3.8: Acidifier 2.0 is again applied and left to pH balance any tackiness to a healthy squeaky feel, is a sign of healthy leather.
3.9: Cleaner 3.8 and Rinse 3.0 system is repeated as above to clean any sticky residue or clean over hidden areas.
4: What is Hydrating and Fatliquoring?
4.1: Hydrating is the process of introducing Hydrator 3.3 into the leather structure to plump it to relax.
4.2: Fatliquoring is the continuous process after hydrating to impart the original ionic negative (-ve) charged fat and oil to hydrogen bond with the leather protein fiber, with its fat that plumps the leather for fullness and the oil that lubricates the millions of connecting fiber like hinges to move over one another smoothly, with softness and strength.
5: How Hydrator 3.3 and Fatliquor 5.0 works?
5.1: Hydrator 3.3 is a water-based pH 3.3 hydrating conditioner that relaxes and plumps soft leather fibers with strength for easy stretching. and shaving existing topcoats.
5.2: For shaving existing topcoats, the leather structure becomes stretchable against the stiffer topcoats causing the aging topcoat to shiver for easy shaving.
5.3: Fatliquor 5.0 is a pH 5.0 ionic negative (-ve) charged micro-emulsion of fat, oil, and water for conditioning leather softness with strength when dry.
5.4: Fatliquor 5.0 on application, the water-encased ionic charged fat and oil molecule breaks free when attraction takes place between the fat and oil with the leather protein fiber.
5.5: The excess free water wicks out leaving a breathing space behind for leather's natural transpiration.
6: How to work with Hydrator 3.3 and Fatliquor 5.0 system?
6.1: Hydrator 3.3 is applied and brushed using a horsehair Leather Brush 1 to distribute and be absorbed into the leather structure.
6.2: When the leather appears evenly with moisture saturation, staking, massaging, and flexing return to dimension and is ready for fatliquoring.
6.3: Fatliquor 5.0 is applied and brushed to distribute and be absorbed into the leather structure.
6.4: Fatliquor 5.0 is repeatedly applied each time the water content evaporates and until the leather takes no more, let to slow drying, and the surface residue is further worked in with Hydrator 3.3 until it turns clear, and let to slow drying again.
6.5: Before it is fully dried, staking, massaging, or flexing until fully dry will result in softer leather.
6.6: Darkening effect after drying is reduce by stretching with a table spoon, or Razor 60 and is ready for topcoat refinishing and or protective conditioning.
7: What is Aniline Topcoat Refinishing?
7.1: Topcoat refinishing preparation varies depending on the extent of the physical damage and the conditions of the topcoat itself.
7.2: In most cases, partial or total removal is recommended to provide a stronger foundation and even out appearance uniformly.
7.3: Degreaser 2.2 followed by Acidifier 2.0 degreasing system is normally the first step.
7.4: Followed by sanding as the second step for physical damage repairs, damages caused by stains that darken will need shaving off the topcoat entirely with Razor 60 in conjunction with Hydrator 3.3 and Fatliquor 5.0 hydrating and conditioning system.
7.5: The third step is the removal of resurfaced soiling particulate's appearance to satisfaction and pH balancing any tackiness with Acidifier 2.0 before topcoat refinishing.
7.6: Topcoat refinishing with a lint-free folding towel is recommended and let dry between coatings to the desired result.
7.7: The final sequence of steps is the application of Protector B to reduce friction wear to the topcoat and reduce soiling with a non-stick protective shield.
8: What is Aniline Gloss Topcoat 76G
8.1: Aniline Gloss Topcoat 76G is a water-based fine particular size urethane-resin emulsion clear gloss topcoat to protect natural tanning color and aniline dyestuff with excellent toughness and flexibility.
9: How to work with Aniline Gloss Topcoat 76G?
9.1: The leather is inspected especially the stained area typically turns dark when soiling particulates resurface.
9.2: Stretching with a tablespoon, brushing, erasing, and shaving with optional Razor 60 will lighten up the appearance.
9.3: Any sanding required is after the first coating has dried to smooth out without damage to the leather grain.
9.4: First coating with a lint-free folding towel is recommended, follow with other methods of topcoat applications like using a foam brush, roller brush, varnishing brush or airbrushing to produce a professional result.
9.5: Let dry between the coating and further fine sanding to smooth out continues in between coatings to satisfaction.
9.6: Let the topcoat cure overnight for extra strength and inspection before the non-stick protection.
10: What is a Rub-resistant, Non-stick Protector?
10.1: A rub-resistant protector imparts a buttery feel that lubricates the leather surface against friction rubs.
10.2: Its non-stick properties reduces sticky soiling and fails the ballpoint to spin out its nasty ink.
11: How to work with Leather Protector B?
11.1: Protector B is applied and spread with a folding towel for an even appearance, let dry, and ready to use.
11.2: Protector B imparts non-stick, rub-resistant protection with a buttery feel to reduce leather topcoat wears from friction rubs.
11.3: Protector B Plus is the leather scent version.
12: What is Aniline Leather?
Aniline leather is leather that has dyed through to the reverse suede side with transparent aniline dyestuff. The surface is further dye coated to even out appearance and sealed with a urethane clear gloss topcoat to bring the beauty of the grain surface show through.
13: Why Products in Concentrates?
Concentrate product has an indefinite shelf life, reduces freezing damages, reduces handling damages, and save cost on shipping weight. Concentrates is easily mixed with distilled water before use.
14: What is a Leather Wet Processing?
Wet processing is a continuous system that includes the working sequence of Degreaser 2.2 followed by Acidifier 2.0, followed by Rinse 3.0, followed by Hydrator 3.3, and ends with Fatliquor 5.0. The leather is at a continuous wet stage extraction with a cotton terry towel until it is dry throughout the product applications. Hydrator 3.3 is again used after Fatliquor 5.0 to clean up any surface residue. It is then left to slow natural dry and when almost dry a little stretching to dry produces the softest leather, in terms of softness and strength.
15: What is Leather Dry Processing?
The dry process begins by stretching with a tablespoon, erase with Eraser 4 and shave with Razor-60 is an option to remove wick-up surface residues. Aniline Gloss Topcoat 76G first coating is applied with lint-free towel padding, followed by hand brushing, roller brushing, varnishing brushing or air brushing for professional result. Sand2000 may be an option to use in-between coatings. Sanding on the leather crust alone is not recommended. Protector B is the end of the Dry Process.
