What is the difference between water-based paint and polyester paint in paint?
Polyester paint for the three components: the main paint, thinner, curing agent: the main agent is unsaturated polyester styrene solution, in addition to the initiator (also known as curing agent, hardener, common name white water) and accelerator And the unsaturated double bond in the main chain of the unsaturated polyester is subjected to free radical copolymerization with an ethylenic monomer (styrene) as an active solvent to cure the film.
Polyester paint is also called unsaturated polyester paint, it is a multi-component paint, polyester resin is the main film made of a thick paint. Polyester paint film fullness, thick layer of hard surface. Polyester paint also has a varnish variety, called polyester varnish. Polyester paint in the construction process need to be cured, the weight of these curing agent accounted for one-third of the total weight of paint. These curing agents are also known as hardeners, the main component of which is TDI (toluene diisocyanate / toluenediisocyanate). These in the free state of the TDI will turn yellow, not only make the furniture paint yellow, also will make the adjacent wall yellow, which is a major drawback of polyester paint.
Water-based paint is a water-based thinner, organic solvent-free paint. Film full, crystal translucent, good flexibility and has a water, wear, anti-aging, anti-yellowing, fast drying, easy to use and so on. Can be used in: wood, metal, plastic, glass, building surface and other materials.
Such as all of our interior and exterior paint, metal paint, car paint and so have the corresponding water-based paint products. Visible water-based paint in many industries has been widely used. We are generally concerned about the water-based wood paint, wood coatings is the technical difficulty and the highest technological content of the product. Water-based wood paint with its non-toxic environmental protection, odorless, volatile very little, non-combustible non-explosive high security, no yellowing, brushing area, etc., with the people's awareness of environmental protection, more and more by the market Welcome.
