Use of spiro-orthosilicates as blocked polyols/reactive diluents in high-solid PUR clear coats for car refinish applications was written by van den Berg, K. J.;van Oorschot, R.;van der Ven, L. G. J.. And the article was included in Surface Coatings International in 2006.Recommanded Product: 2-Butyl-2-ethylpropane-1,3-diol 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: 115-84-4Recommanded Product: 2-Butyl-2-ethylpropane-1,3-diol).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. 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.Recommanded Product: 2-Butyl-2-ethylpropane-1,3-diol
