Castor oil is a triglyceride of fatty acids. Castor oil is found in castor beans In the seeds, its content is 35% to 57.%. “Castor oil is obtained by squeezing or solvent extraction. It is almost colorless or slightly yellow, clear and viscous liquid; has a slight odor; has a light taste and then is slightly pungent, and is easily soluble in ethanol. , can be freely mixed with absolute ethanol, chloroform, ether or glacial acetic acid, and should be widely used in coatings.
Castor oil is a non-drying oil that can be dehydrated by vacuum dehydration at high temperatures or in the presence of catalysts. The molecule becomes a conjugated or non-conjugated dienoic acid structure, that is, dry dehydrated castor oil.
The functions and characteristics of dehydrated castor oil:
Dehydrated castor oil is mainly used in coatings, inks, polyurethane waterproof materials, etc. It can completely replace tung oil and make up for the shortcomings of tung oil. It gives coatings good flexibility, toughness, quick drying, excellent color retention, and water resistance. performance, so it is mostly used in industries such as ships (such as ocean-going ships, large ships, etc.), aerospace (such as aircraft), transportation (such as high-end cars, rail trains, etc.), underground waterproofing (such as underground tunnels, underground transportation, etc.).
Dehydrated castor oil is popular in the printing ink industry for its properties of non-discoloration, impermeability, cleanability and brightness. It is especially effective in phenolic blended paints, alkyd resin paints, epoxy resin paints, and metal exterior paints. Good.
Dehydrated castor oil is a renewable energy source, biodegrades well, and does not cause pollution to the atmospheric environment. Therefore, intramolecular dehydrated castor oil is an environmentally friendly green product.
