Solvents
Solvents are the most effective cleaning agents for industrial cleaning. Currently there are types that differ greatly and have various applications.
Chlorinated solvents.
Although they are highly effective, chlorinated solvents have a high level of toxicity, meaning their use is even more limited.
Amongst these products we have trichlorethylene (R45) and perchlorethylene (R40).
Brominated solvents.
A clear substitute for chlorinated solvents due to their equal cleaning performance.
The Hidrofluoreters and hydrofluorocarbons.
These are the most ecological solvents. Although they do not have the same cleaning power, their combination with hydrocarbons or modified alcohols make them as effective as previous cleaners but with less risk of toxicity.
