A solvent is widely used to disperse or dissolve various components that are used in the formulation in coatings and paintings. One can find different types of industrial paints such as organic coatings – alkyd coatings, epoxy coatings, polyurethane coatings and inorganic coatings – acrylic coatings, ceramic coatings, intumescent coatings. Epoxy paints define high performance and large of coating products that pack up with excellent mechanical, film-building and chemical properties also with short drying and curing duration. There are many paint companies in India that provide the best paints which many of the well-known industries and factories use. One can find many types of solvents that are used in paints and coatings namely hydrocarbon solvents, ketones, esters, alcohols and glycol ethers.
Solvents play a vital role in many of the products that the customers use such as to create paint in the desired consistency to avoid globs or clums and for application, in paints, disperse or dissolve the components used in the paint formulation. In some spray paints glycol ether esters are added to prevent them from drying in the mid-air. It is added coatings and paints formulations that dissolve additional compounds like pigments, additives and binders. Cyclic hydrocarbon, linear or branched chains such as pure solvent like hexane are called aliphatic solvents. Like Toulene and Xylene, aromatic solvents feature a benzene group. One can find many paint companies in India that provides the best services and products.
There are different types of industrial paints that one can find in the market. Solvents role is important in coating formulation even if they’re not present in the final stage due to evaporation and control viscosity for the application. Epoxy paints have many characteristics including performance. They have a vital effect on film quality as they are strongly dependent on the evaporation rate during drying. When it comes to the great solvating ability, ketones solvents are considered in that criteria which is due to carbonyl group – a hydrogen acceptor. For polar resins, these are good as they are critical for higher ketones and in short they become favourable for non-polar resins while only tiny of the ketones are miscible with water. Esters have similar solvating power like ketones as they also are hydrogen acceptors and if small ester is great solvents for polar resins and their dissolving for non-polar boosts like ketones.
Alcohol is both hydrogen acceptors and donors that gives them a tremendous solvating power for polar resins, OH group has its influence on it as it’s in the same position. The solvating power for polar resins decreases as the breadth of hydrocarbon chain increases. Miscibility falls from the hydrocarbon chain length are lengthy and in water, small alcohols are soluble. One need to know that alcohol react to isocyanates that can interfere with the drying process of coatings which can be reduced by adding secondary alcohols or tertiary alcohol.
Glycol Ether solvents are divided into two namely E-series – based on ethylene and P-series – based on propylene.
