EINECS 241-431-6 - Introduction
(diphenylsilylene)bis(oxy-2,1-ethanediyl) bismethacrylate, also known as TMSPMA, is an organosilicon compound.
Nature:
1. Appearance: TMSPMA is a colorless to light yellow liquid.
2. Solubility: TMSPMA is soluble in common organic solvents, such as toluene, benzene and ethanol.
3. Melting point and boiling point: Since TMSPMA is usually used in liquid form, its accurate melting point and boiling point data are rarely reported.
Use:
1. Crosslinking agent: TMSPMA can be used as a monomer for the preparation of polymer crosslinking agent, such as UV curing coatings, adhesives and optical films.
2. Surface treatment agent: TMSPMA can be used as a surface treatment agent to provide improved bonding and wetting properties for materials such as ceramics, fibers, glass and metals.
3. Functional Coatings: because TMSPMA has low surface tension and high grafting reactivity, it can be used to prepare Functional coatings with anti-pollution, water resistance and heat resistance.
Method:
The preparation of TMSPMA usually involves the carbonylation of methacrylic acid and the Silylation of the carboxyl group of methacrylic acid.
Safety Information:
1. Toxicity: TMSPMA is a low toxicity compound, however, care should still be taken to avoid contact with skin and eyes. In the case of accidental contact, rinse immediately with plenty of water and seek medical help.
2. Combustibility: TMSPMA has low combustibility, but it may decompose under high temperature conditions to produce harmful gases.
3. Storage and handling: TMSPMA should be stored in a dry, cool place, avoid contact with oxygen, acid or alkali. It is necessary to comply with relevant safety practices, such as wearing appropriate protective equipment.
