Pb in varnishes - serious a problem
One of the earliest known heavy metal was lead, which was used in ancient times. His popularity owes its physical and chemical properties - is primarily easy to process.
Lead and its compounds are highly toxic, even at very low concentrations. For the organisms lead gets easily through the gastrointestinal tract, respiratory system and through the skin. The dose of lead absorbed by an adult human within one week should not be greater than 3 mg, and children who are more susceptible to lead poisoning should not take more than 1 mg in a week. Lead accumulates in the human body. The largest storehouse of lead in the human body are the bones. Lead in bones can stay for 40-90 years. Consequences of its toxic effects may be synthesis blood disorder, hypertension, neuropathy or brain damage.
Lead was one of the reasons for the fall of the Roman Empire. We know that water from the aqueduct was fed by water pipes. These tubes were made of lead. People drank water - saturated with lead, which led to a number of diseases and consequently to death.
Nineteenth and twentieth century’s are common applications of lead in paints for use as a protective layer and decorative in developing dynamically industry with a new branch: the automotive industry. Lead compounds are used to produce pigments which produce automotive paint. It turns out that the pigments (especially yellow) made of lead have a high hiding power, and what is important is inexpensive to manufacture.
Although car manufacturers stopped using lead pigment on the production lines many years ago, it is because the demand for them (low price) they were still offered in industrial paints and renovation. Regulation of the European Parliament called REACH (ang. Registration, Evaluation and Authorisation of Chemicals) on safe use of chemicals introduces significant limitations. Under that regulation, manufacturing, marketing or use of dangerous substances which include heavy metals such as lead and cadmium are prohibited. REACH aims to increase the protection of health and the environment and is valid on the territory of the European Union, Norway, Iceland and Liechtenstein.
Currently, significant company in the market no longer apply in their varnishes toxic lead paints. Among them, they are the same as Multichem that long before the introduction of stringent regulations has developed components that replace those toxic. The new products are not inferior to those of predecessors in terms of a parameter away while they are safe to use.
Using the latest products do not need to worry about the quality of the coating and resistance to weathering product to be free of heavy metals. Thanks to the experience through years of research collected by research and development team obtained new product lines like automotive paint lines Kar-Bon devoid of toxic lead. Coatings from PROFIX brand meet the highest quality standards, ensure the safety of employees and users of paint products.
