What is a Bicast Leather?
Bicast or Bycast is split leather with a layer of polyurethane applied to the surface and then embossed.
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.
Bicast furniture exhibits none of the characteristics associated with aniline wax pull-up leather.
With constant use, bicast leather may develop delamination and peel in the often-flexed area.
The sitting cushion may also develop splits at the weak points, and exposure to inert gases, body oils, grease, and sweat can cause stickiness to the urethane finishes.
What is a Bicast Leather Sticky Problem?
The problem with bicast leather is often described by owners as the finish becoming dull on the seating areas and any material that comes in contact with it sticking to it.
Bicast finishes feel a bit rubbery, but after 5 minutes of sitting, clothing becomes stuck to it.
The area that experiences tackiness also exhibits roughness when touched.
When sitting down or standing up, there is a sound of tape being pulled, and a pattern from jeans can be seen on the couch.
If these experiences sound familiar, then Kit B7 or an upsized content with Kit B7 Plus is the answer.
Why a Holistic System to Solve Bicast Sticky Problem?
Degreaser 2.2 and Acidifier 2.0 system are used for stripping surface contamination.
Eraser 4 is used to remove any accumulated materials from the surface.
Suspended soiling is removed by a towel that is extracted and rinsed with Acidifier 2.0.
A 1000/2000 grit sandpaper or coarser is used to smooth rough surfaces to match.
Bicast Top 76G is a water-based urethane resin emulsion gloss topcoat with excellent flexibility.
Crosslinker 25 is a high-solids auxiliary hardener that binds some of the hydrophilic elements to prevent sticky topcoats when mixed at 10% into the topcoat.
Protector B is a protective non-stick, soft, buttery feel for reducing leather squeaking noise.
It also prevents ballpoint ink from dispersing when it comes in contact with the leather.
This product increases the leather's resistance to wet and dry rubs, reducing stretch, scuffs, and abrasions.

How to reduce sticky topcoat issues?
Bicast leather exposure to inert gases, body oil, grease, and sweat when neglected eventually causes stickiness to the urethane finish.
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.
