Coupling agent.VP Si 525 is a silane silane or silicon hydride Any of a series of inorganic compounds of silicon and hydrogen with covalent bonds and the general chemical formula SinH(2n + 2). coupling agent for silica filled peroxide peroxide (pərŏk`sīd), chemical compound containing two oxygen atoms, each of which is bonded to the other and to a radical or some element other than oxygen; e.g. cured rubber compounds. Compared to the standard silanes for peroxide curing, like vinyltris (2-methoxyethoxy) silane (VTMOEO) or vinyl trimethoxy silane (VTMO), the coupling agent VP Si 525 does not emit toxic substances, neither during production nor during the life cycle of the rubber goods, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. Instead of the evolution of noxious noxious adj. harmful to health, often referring to nuisances. alcohols like 2-methoxyethanol or methanol methanol, methyl alcohol, or wood alcohol, CH3OH, a colorless, flammable liquid that is miscible with water in all proportions. Methanol is a monohydric alcohol. It melts at −97. during the mixing process, only small amounts of ethanol are produced. VP Si 525 reduces the evolution of volatiles by 70%, while providing the same coupling efficiency and product properties, according to the company. Another advantage is said to be the high flash point, which makes handling easier and improves safety aspects remarkably. Comparable product properties can be achieved with significantly lower silane concentrations, according to the company. The required amount of coupling agent can be reduced.
