WHY JOD-32 SEALANT HAS BEEN CREATED?
Already at the beginning of the last decade it became clear that the needs of buyers of sealants depend not only on the value and quality of the product offered. But also from the global process related to energy saving, ecology, the use of renewable energy sources, etc.
This was the start of the European Commission work related to the development of the so-called REACH. Namely, the chemical substances registration system which introduces restrictions on the use of substances that are potentially harmful to humanity and the environment. Mercury is an element commonly used in the polyurethane manufacture based on sealant.
Mercury is dangerous as a chemical element
Since the middle of 1990, humanity began to seek answers to questions about the restrictions on the use of mercury. The restrictions on its use were primarily related to such products as batteries, accumulators, thermometers. And expected that this trend would eventually transfer to other industries. While produce of sealants, people deal with mercury vapors, which are dangerous and very easy penetrate to human body. At that, not only when inhaled, but also through the skin and can cause negative effects. Therefore, it is necessary to avoid this dangerous component of the manufacturing process in order to minimize the potential risk of mercury vapors exposure to humans.
In addition, the final product in the form of a hardener (two-component sealant) containing mercury carries potential risk for users. Instructions and restrictions on the use of such elements always described in the material safety certificate (the so-called MSDS). However, there is a risk and practice associated with the possibility of “scorches” because of contact with the component, various allergic reactions, etc.
Create of JOD-32 sealant without mercury
All of this has led the fact of creation a new type of non-mercury-free polyurethane sealant in 2012 called JOD-32 by the GRAN POLYCHEM company. The recipe was developed, patented and carefully refined with the help of the GRAN POLYCHEM research team.
The works carried out in the GRAN laboratory were also associated with the possibility of using alternative raw materials to reduce the cost of the product without compromising the quality of a final mass. This led to the flawless ratio “price-quality”.
