What solvents belong to aromatic hydrocarbons? Aromatic hydrocarbons are composed of carbon and hydrogen ring molecules. The best known aromatic solvent is benzene, from which other aromatic compounds are derived, such as toluene, xylene and styrene. Because benzene has been found to be carcinogenic, it must not be used as a solvent for binders.
Aromatic hydrocarbons are often used as diluents. Styrene – due to its reactive double bond – is used as a solvent for unsaturated polyester resins. It reacts during curing by polymerization with the unsaturated polyester resin.
How is styrene different from other solvents, when it is used in varnishes on unsaturated polyester resins? While the solvents, when drying (curing) varnishes and paints, they usually evaporate, it is styrene that reacts chemically when hardening varnishes and paints on unsaturated polyester resins by polymerization with unsaturated polyester resin and becomes a component of the binder. This also explains the high content of non-volatile components in varnishes and paints based on unsaturated polyester resins.
For which binders can be solvents alcohols? Alcohols can be a solvent for shellac and some nitrocellulose varnishes. Alcohol is usually used in the form of spirit. It is ethanol, to which ingredients that make it unfit for consumption are added. Alcohols are also included in many special thinners as fillers.
What solvents are contained in the so-called. thinners for polymer resins?
The so-called. diluents for polymer resins contain aromatic compounds in addition to white spirit, as well as esters, ethers and alcohols.
For which varnishes and paints the so-called. thinner for polymer resins?
The so-called. the thinner for polymer resins is suitable for varnishes and alkyd paints. Some polymer resin thinners are also suitable for varnishes and oil paints, Cyclocanuchetch, for bituminous and asphalt paints. Thinners for these resins are usually developed by the manufacturer of a specific varnish or paint – specifically for the product. To avoid coating defects, such as e.g.. bad flow, always use the diluent specified by the manufacturer.
What solvents does the so-called. nitro thinner? The nitro thinner is a mixture of esters, ketones, aromatic compounds and alcohols.
What solvents are contained in coating removers? Coating removers contain a mixture of solvents, consisting of esters, ketones, aromatics and tetralin. As a rule, the use of chlorinated hydrocarbons is not used – for health and environmental reasons.
What solvents are contained in special thinners for epoxy varnishes?
Special thinners for epoxy varnishes contain ketones, ethers, Aromatic compounds and alcohols.
What solvents are included in special thinners for polyurethane varnishes?
Special thinners for polyurethane varnishes mainly contain esters and ketones.
What solvents are included in special thinners for chlorinated rubber paints?
Special thinners for chlorinated rubber paints contain esters, ketones and ethers.
