 and adhesives. These materials are noted for their versatility, but their relatively high cost has limited their use. High resistance to chemicals and outstanding adhesion, durability, and toughness have made them valuable as coatings. Because of their high electrical resistance, durability at high and low temperatures, and the ease with which they can be poured or cast without forming bubbles, epoxy resin plastics are especially useful for encapsulating electrical and electronic components. Epoxy resin adhesives can be used on metals, construction materials, and most other synthetic resins. They are strong enough to be used in place of rivets and welds in certain industrial applications.

The global waterborne epoxy resins market was valued at US$ 2,764.0 Mn in 2018, according to Waterborne Epoxy Resins Market Report, by Product Form (Liquid, Semi-Solid, and Solid), by Molecular Weight (Low Molecular Weight and High Molecular Weight), by Application (Adhesives, Coatings, Composites, and Others), by End-use Industry (Construction, Automotive, Textile, Packaging, and Others), and by Region (North America, Latin America, Asia Pacific, Europe, Middle East, and Africa) published by Coherent Market Insights.
Then, towards the end of May, some of the Chinese epoxy resins producers and their downstream customers were given permission to restart.
Therefore, various additives from polymers to inorganic materials were used to modify cyanate esters such as polymeric microcapsules [3], polymeric microspheres (porous crosslinked poly(phenylene oxide)-epoxy polymer) [6], polyhedral oligomeric silsesquioxane [13, 16J, carbon-based materials [7, 9, 17-21], titanium dioxide [22], montmorillonite clay [12], epoxy resin [13, 23], polysiloxane, and butadiene-acrylonitrile rubbers [10].
New epoxy resin dispersions and unique water-borne curing agents are available for metal coatings that combine each of these important attributes.
The effect of these combined treatments on the impact toughness and hardness of their composites with epoxy resin is also looked into.
