1. What is a Bicast Leather?
1.1: Bicast or Bycast is split leather with a layer of polyurethane applied to the surface and then embossed.
1.2: Bicast, as a result, is a slightly stiffer product that is cheaper than top-grain leather but has a much more consistent texture and is easier to clean and maintain.
1.3: Bicast furniture exhibits none of the characteristics associated with aniline wax pull-up leather.
1.4: Bicast leather may develop delaminating in the often constant use of the flexed area.
1.5:The sitting cushion may also develop splits at the weak points, and exposure to inert gases, body oils, grease, and sweat causes stickiness to the urethane finishes.
2: What is a Bicast Leather Sticky Problem?
2.1: Owners often describe the problem with Bicast leather as the finish becoming dull on the seating areas and any material that comes in contact with it sticking to it.
2.2: After 5 minutes of sitting, deteriorating Bicast feels rubbery and the clothing becomes stuck.
2.3: The area that experiences tackiness also exhibits roughness when touched.
2.4: There is a sound of tape being pulled when sitting down and getting up and a pattern from jeans can be seen on the couch.
2.5: If these experiences sound familiar, then this Kit B7 Plus is the answer.
3: Why a Holistic System to Solve Bicast Sticky Problem?
3.1: Degreaser 2.2 and Acidifier 2.0 systems are used for restorative cleaning and pH balancing to reduce stickiness.
3.2: Eraser 4 removes accumulated materials from the surface.
3.4: Suspended soiling is removed by towel extraction and rinsed with Acidifier 2.0.
3.5: A 1000/2000 grit or matching coarser sandpaper smooths rough surfaces.
3.6: Bicast Gloss Topcoat 76G is a water-based urethane resin emulsion gloss topcoat with excellent flexibility.
3.7: Crosslinker is a high-solids auxiliary hardener that binds some hydrophilic elements to prevent sticky topcoats when mixed into the topcoat.
3.8: Protector B is a protective non-stick, soft, buttery feel for reducing leather stickiness and squeaking noise.
4: How a 3-Step Process Solves the Bicast Sticky Issue.
4.1: Degreasing System by Degreaser 2.2 and Acidifier 2.0.

5: How to work with Degreaser 2.2 and Acidifier 2.0 systems?
5.1: Degreaser 2.2 is shaken until it gels from separation.
5.2: Swirl the marble around for about 5 minutes to see the coagulation building up from the bottom, when the coagulation reaches 75% level give it a vigorous shake to gel.
5.3: Saturate to reach penetrated soiling with appropriate brushes and erasers to remove accumulated soiling and extract with a dry terry cotton towel until the towel shows clean.
5.4: Acidifier 2.0 is applied and worked by brushing and erasing, then towel extracted until folding sides are clean.
5.5: Let it dry or blow dry it.
5.6: Rough surfaces are smoothed with appropriate sandpaper and rinsed clean, free of dust and lint, with a towel.
5.7: Let it dry, or use a hair dryer to blow it dry.
5.8: It is now ready for top coating.
6: How to work with the Bicast Gloss Topcoat 76G and Crosslinker system?
6.1: Add 4oz ready-to-use Bicast Gloss Topcoat 76G into the 1.25gm Crosslinker Bottle.
6.2: Add a little at a time while swirling to avoid seeding.
6.3: Swirl well for 2-3 minutes to ensure proper mix.
6.4: Allow the mixture to react for at least 30 minutes before using.
6.5: This will ensure optimum catalyst reaction time and flow/leveling performance of the coating during application.
6.6: This optimum catalyst reaction time ensures the flow and level performance of the coating during application.
6.7: After 48 hours, it is recommended to re-cross-link the top coat.
6.8:The mix is transferred to the foam brush and applied in a light circular motion to avoid streaks.
6.9: Blow dry to avoid streaking on subsequent coatings.
6.10: Subsequent light touching coatings are applied until the desired gloss is achieved and let overnight for curing.
6.11: Allow at least 48 hours for a complete curing before use.

8: How to Reduce Sticky Topcoat Issues?
8.1: Bicast leather exposure to inert gases, body oil, grease, and sweat when neglected eventually causes stickiness to the urethane finish.
8.2: A preventive solution to reduce potential stickiness is to use a low-pH product system to clean and neutralize alkaline soiling, especially from fermenting sweat.
8.3: A 3-step holistic system includes Bicast Pro 1.5, Acidifier 2.0, and Protector B.
8.4: Bicast Pro 1.5 is cleaner to rectify sticky Bicast leather from body oil, grease, sweat, and unknown alkaline cleaners.
