Finish First Polish is composed of three thermodynamic phases, each which plays a vital part in the working of the polish. The interaction of the three phases – application, drying, and buffing are all crucial steps in maximizing the appearance of the automobile finish. When Finish First Polish is rubbed into the car, the emulsified form of the polish is broken and the synthetic polymer precursors which form the protective coating are mixed with the reaction initiator. The polymer precursors are highly surface active and quickly migrate to the surface where they become chemically bonded to the paint. The buffing agent which is present in Finish First Polish acts to lift weathered paint and scrub out tar, road film and dirt. It also serves as a vehicle on which old wax and material dissolved by the polish is removed.
During the drying period, which begins immediately after application, the polish takes on an appearance of a haze. The carriers of the synthetic polymer precursors and intiator evaporate, leaving behind the polymer in concentrated form.
The polymer precursors quickly transfer themselves from a low viscosity, low molecular weight liquid into a high molecular weight glassy solid. This process is known as curing. The rate of curing is controlled primarily by temperature, but relative humidity also has a role. The think liquid form of the polymer precursors makes the polish spread easily.
Each synthetic precursor has four functional groups attached to it. One group is responsible for water repellency, another for binding to paint, and the remaining two for linkage with other polymer precursors and network formation. A co-polymer which is admixed with the principle monomer, is also tetrafuctional but has one group for water repellency and three for network formation. This extra group for linkage causes the network to grow in three dimensions, making the coating tough.
When polymerization has progressed a sufficient degree, the haze can be buffed out with a soft cloth. Buffing removes the buffing agent, any surface contaminants adhering to it and any other solid debris such as dead paint. It also smoothes out the polymeric film. Since the buffing agent is embedded in the polymer coating, it is important to apply to polish in a thin coat and allow the coat to dry completely. This minimizes the difficulty to buff out.
The cured polymeric coating forms a thin transparent film on the car. Because this film is optically flat and mirror-like, it reflects light coherently. This reflection of light serves to fuse ultra-violet rays and creates an exceptional sunblock to retard oxidation and sun fading. The effect of coherent reflection off a car is perceived as gloss and creates the impression of depth. The film also has the property of water repellency and is why the film is able to prevent water and waterborne materials from migrating to the paint.
Finish First Polish out performs conventional waxes or polishes. Waxes have poor adhesion to automotive paint, limited weather resistance and offer little protection. They can be difficult to spread and buff out. Because of the problem of buffing, a conventional wax may not give a particularly good shine because a coating that’s hard to buff will be difficult to make optically flat. Wax also lacks the ability to build up layers because the solvent of the second coat destroys the first coat.
Silicone-based polishes do not polymerize to chemically adhere to the paint. Finishes polished with these products look wet because they are wet. Silicones impart good gloss, are easy to work with and last in service as long as conventional waxes.
Some polishes contain PTFE (Polytera Flourethelene) either as a primary ingredient or mixed with waxes. PTFE is present as microscopic particles which are non-curing. Rubbing the car with a PTFE product burnishes the particles into the paint. While PTFE imparts good water and solvent repellency, the shine may not last long. The durability of the PTFE coating is adequate but it has no means of chemically bonding itself to the paint or of crosslinking between particles.
Our research and development of synthetic based surface care products has led to our quality which has set a standard in the automotive appearance products market.
