People Also Ask:
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.
What is Aniline Leather Degreasing?
Degreasing or removing surface and penetrated grease is essential for good topcoat bonding, just like any other refinishing work base on the same principle. 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. Otherwise, a high pH value bleeds the dyestuff and displaced it with blotchiness. High pH or alkalinity degreaser denatures the leather when the tanning agents leach out resulting in tackiness and in the worst case sliminess. 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. When degreasing existing cracks or dried leathers of fatliquor contents below 7% when read with a leather moisture meter, it is recommended that hydrating it with Hydrator-3.3 prior to Fatliquor-5.0 first to top-up the fatliquor content up to the original 14% prior to degreasing. Preconditioning helps prevent over-drying of the leather during the degreasing process that may accentuate or magnifies existing cracks.
What is Aniline Topcoat Refinishing?
Topcoat refinishing preparation varies depending on the extent of the physical damage and the conditions of the topcoat itself. In most cases, partial or total removal is recommended to provide a stronger foundation and even-out appearance uniformly. Leather Degreaser-2.2 followed by Leather Acidifier-2.0 degreasing system is normally the first step, follows 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. The third step is the removal of resurfaced soiling particulate's appearance to satisfaction and pH balancing any tackiness with Leather Acidifier-2.0 prior to topcoat refinishing. Topcoat refinishing with a lint-free folding towel is recommended and let dry between coatings to the desired result. The final sequence of steps is the application of Leather Protector-B to reduce friction wear to the topcoat and reduce soiling with a non-stick protective shield. Note: To rectify existing finish tackiness or extra water resistance adds up to 10% Leather Crosslinker-25 to Leather Aniline Top-76.
'Why these Products are Picked as a Holistic System to Degrease Aniline leather?'
The answer is . . .
Degreaser-2.2, Acidifier-2.0, Cleaner-3.8, and Rinse-3.0 system!
Leather 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.
Leather 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.
Leather Cleaner-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 Leather Rinse-3.0 to return the leather to its pH chemistry integrity.
Leather 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.
Hydrator-3.3 and Fatliquor-5.0 system!
Leather 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. The leather structure becomes stretchable against the stiffer topcoats causing the aging topcoat to shiver for easy shaving.
Leather 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.
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. The excess free water wicks out leaving a breathing space behind for leather's natural transpiration.
Leather Aniline Top-76!
Top-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.
Leather Protector-B imparts non-stick, rub-resistant protection with a buttery feel to reduce leather topcoat wears from friction rubs.
Why Products in Concentrates?
Concentrate product has an indefinite shelf life, does not freeze, has less handling damage, and save cost on shipping weight. Concentrates in the bottle have to be cut/mixed with distilled water prior to use.
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.
How to work with Degreaser-2.2, Acidifier-2.0, Cleaner-3.8, and Rinse-3.0 system?
1- Apply Degreaser-2.2 after shaking it well, saturating sufficiently where apparent body contact soiling is evident and feather out to less body contact soiling areas.
2- Leather Eraser-4 is used for better traction without the risk of scratching the finishes.
3- Horsehair Brush-1 is used for stitching rows, welting, groves, creases, and wrinkles,
4- Emulsified and suspended soiling are extracted with a dry cotton terry towel until it shows clean.
5- Acidifier-2.0 is sprayed, brushed, and erased followed by towel extraction changing folding sides until the towel shows clean.
6- Acidifier-2.0 is again sprayed and left to pH balance if tackiness persists until a squeaky feel with finger testing is a sign of healthy leather.
7- Cleaner-3.8 and Rinse-3.0 system is repeated as above to clean any sticky residue or clean over hidden areas.
How to work with Hydrator-3.3 and Fatliquor-5.0 system?
1- Hydrator-3.3 is sprayed and brushed using a horsehair leather Brush-1 to distribute and be absorbed into the leather structure.
2- When the leather appears evenly with moisture saturation, staking, massaging, and flexing return to dimension and is ready for fatliquoring.
3- Leather Fatliquor-5.0 is sprayed and brushed to distribute and be absorbed into the leather structure.
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.
5- Before it is fully dried, staking, massaging, or flexing until fully dry will result in softer leather, and ready for protective conditioning.
What is Leather Dry Processing?
The dry process begins with Eraser-4 and Leather Razor-60 is an option to remove wick-up surface residues. Aniline Top-76G is applied best with lint-free towel padding. Sand2000 may be an option to use in-between coatings. Sanding on the leather crust alone is not recommended. Leather Protector-B is the end of the Dry Process.
How to work with Leather Aniline Top-76?
1- The leather is inspected especially the stained area typically turns dark when soiling particulates resurface.
2- Stretching, brushing, erasing, and shaving with optional Razor-60 will lighten up the appearance.
3- Any sanding required is after the first coating has dried to smooth out without damage to the leather grain.
4- Coating with a lint-free folding towel is recommended among other methods of topcoat applications.
5- Let dry between the coating and further fine sanding to smooth out continues in between coatings to satisfaction.
6- Let the topcoat cure overnight for extra strength and inspection before the non-stick protection.
How to work with Leather Protector-B?
1- Protector-B is sprayed and spread with a folding towel for an even appearance, let dry, and ready to use.
