Propylene glycol ether and ethylene glycol ether are both diol ether solvents. Propylene glycol methyl ether has a slight ether smell, but no strong irritating odor, which makes its use more extensive and safer.
What are the uses of PM CAS 107-98-2?
1. Mainly used as solvent, dispersant and diluent, also used as fuel antifreeze, extractant, etc.
2. 1-Methoxy-2-propanol CAS 107-98-2 is an intermediate of the herbicide isopropylamine.
3. Used as solvent, dispersant or diluent in coatings, inks, printing and dyeing, pesticides, cellulose, acrylate and other industries. It can also be used as a raw material for organic synthesis.
Water-based coatings and propylene glycol methyl ether:
Currently, the coatings on the market can be divided into water-based coatings, solvent-based coatings, powder coatings, high-solid coatings, etc. according to their forms. Among them, water-based coatings refer to coatings that use water as a diluent. The volatile organic solvents are very small, only 5% to 10% of solvent-based coatings, and are green and environmentally friendly products.
To make green and environmentally friendly water-based coatings, there is an indispensable chemical raw material – that is propylene glycol methyl ether. What is the role of propylene glycol methyl ether as a solvent in water-based coatings?
(1) Dissolving water-based coating resins: Propylene glycol methyl ether is a high-boiling point, low-density solvent that can dissolve the resin in water-based coatings to form a uniform mixture, thereby improving the fluidity and solubility of water-based coatings.
(2) Improving the physical properties of water-based coatings: It has a lower density and higher vapor pressure, so it can improve the physical properties of water-based coatings, such as increasing the viscosity of the coating and maintaining the stability of the coating.
(3) Improve the durability of water-based coatings: It has good chemical stability and antioxidant properties, which can provide excellent durability and chemical resistance for water-based coatings.
(4) Reduce the odor of water-based coatings: It has a lower odor, which can reduce the odor emitted by water-based coatings and improve the comfort and safety of coatings.
In short, propylene glycol methyl ether has good solvent properties and physical properties in water-based coatings, which can provide important support for improving the performance and durability of water-based coatings. At the same time, it can also reduce the odor of water-based coatings and the release of harmful substances, and improve the safety and environmental protection of coatings.
