Solvents
There are three main types;
1. Oxygenated Solvents- alcohols, glycol ethers, ketones, esters, and glycol ether esters. Oxygenated solvents are synthesized from other chemicals to form the desired solvent. Those solvents are typically of a high purity with specifications ranging from 99.0% to 99.9% purity.
2. Hydrocarbon Solvents (Petroleum Distillates) - aliphatic (include methane, propane, and kerosene, they are flammable and may be explosively flammable).
3. Aromatic hydrocarbons- which are the most toxic compounds found in petroleum products and include such substances as para-xylene (Benzene, Toluene, Ethyl benzene, and Xylene), which are all volatile organic compounds (VOC)
Notes- when using solvents always use Nitrile medical gloves (usually the blue or purple ones) if you are going to be using them for any length of time.
Solvents are used for chemical cleaning, and as a carrier system, it also makes products workable and to provide spread ability, as is the case with Carnauba wax, which in its natural state is rock hard.
The low surface tension of silicones is sometimes added to solvents to improve the wetting ability and to improve the surface contact.
Solvents require an aerobic cure (exposure to air) to allow them to evaporate (outgas); some solvents contain formaldehyde, which dissolves both natural rubber and synthetic compounds, and some contain petroleum distillates specifically hydrocarbon and oxygenated solvents, which represent most of the total organic solvents used.
Organic solvents can be classified by chemical structure, for example water is a solvent, but is inorganic. Solvents provide solubility for the other ingredients, dependent upon the type of solvent used will determine the product's drying time.
Use a safe solvent; Anhydrous Isopropyl alcohol , Isoamyl acetate(Banana oil) or d-Limonene (citrus based) that does not contain any harmful components (Butyl, Heptanes or Xylene or hydrocarbon aliphatic solvents) With all cleaning products (especially solvents) always test a small inconspicuous area first to ensure it won't discolour, stain or etch the surface, and ensure that the pH of the product is suitable for the material
After the paint surface has been subjected to a chemical cleaning its protective layer (s) have been removed and the paint surface left without protection, so it is very important that a wax or polymer protection be applied immediately.
MSDS
Read the manufacturers application instructions and then obtain and read the MSDS sheet to ascertain the chemicals used, although it should be said that an MSDS is a document that contains details of the hazards associated with a particular chemical and provides information regarding its safe use. The MSDS is required to state the chemical's risks, safety and impact on the environment.
Environmental Commitment- always dispose of all non-biodegradable materials from your vehicle cleaning in a responsible manner
