With a lot of construction activities going on in the world, and especially in the APAC region, home to two of the most populated nations, China and India, mainly to provide housing to the increasing population. it will also have a positive impact on the demand of paints and coatings as well.
Let us start:
Solvents have an important role to play in many customer-use products for making paint, with a good consistency avoid clumps and for application, in paints, dissolve the components, which are used in the making of paints and coatings.
Glycol ether esters are added to the paints for resisting them from drying in the mid-air. It is added to paints formulations dissolving additional compounds, such as, additives, pigments and binders.
Solvents Have an Important Role
Solvents are important in the formulation of coatings even if they’re not there at the final stage because of evaporation and control viscosity for the use.
These are good for polar resins as they are important for higher ketones and favorable for non-polar resins when only tiny ketones are mixable with water.
Esters have solvating power just as ketones as they also accept hydrogen and if small ester works well as a solvent for polar resins and their dissolving for non-polar boosts just as ketones.
Alcohol is Both Acceptor and Donor of Hydrogen
Alcohol is both hydrogen acceptor and donor that giving them an incredible solvating power for polar resins, OH group has its effect on it as it is in the same position.
Alcohol reacting to isocyanates that can interfere with the process of drying of coatings can be reduced by the addition of secondary or tertiary alcohol.
So, all in all solvents have a big role to play in the formulation of coatings and prevent them from drying. With the growing construction sector in the Asia Pacific, the demand for paints and coatings is on the rise and will reach USD 133.03 billion by the end of this decade.
