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 107-98-2is 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.
