Use of spiro-orthosilicates as blocked polyol/reactive diluent in high solids PUR clearcoats for car refinish applications was written by van den Berg, Keimpe J.;van Oorschot, Ren;van der Ven, Leo G. J.. And the article was included in Pitture e Vernici, European Coatings in 2006.SDS of cas: 115-84-4 The following contents are mentioned in the article:
Spiro-orthosilicates, prepared from tetra-Et orthosilicate and a diol (2-butyl-2-ethyl-1,3-propanediol or 2-ethyl-1,3-hexanediol), were used as latent reactive diluent in two-pack polyurethane coatings. A fast curing and long pot life was achieved due to the latency in the can. Spiro-orthosilicates hydrolyze with moisture forming a diol and a polysiloxane. Kinetic data on hydrolysis and curing are given. The formation of polysiloxane was characterized by solid state Si NMR. The spiro-orthosilicates based films were tested as clearcoat for refinishing of automobiles. The coatings showed good stability after many car washes. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4SDS of cas: 115-84-4).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.SDS of cas: 115-84-4
