Smartening up appearance and function
Applied to surfaces or parts of surfaces, coatings can be either decorative or functional or both.
Decorative coatings add color, texture and effects, making items eye-catching and attractive. Functional coatings provide protection against damage caused by light and heat, corrosion and weathering, scratching and abrasion, microbial attack, and more.
Coatings create appeal and provide a wealth of different functions
Coatings are an important area in chemicals and used in a wide variety of industries. Like most of the industries it serves, the coating sector aims at enhancing quality while saving costs. Other trends driving developments in coatings are the increasingly stringent emission regulations in many countries as well as other environmental considerations.
Coatings, which are supplied in a variety of physical forms, can be either water- or solvent-based. Intense efforts are being made to replace solvent- with waterborne coating technologies and to reduce generation of volatile organic compounds (VOCs).
The sector benefits from a special additional trend: coatings are able to provide individuality, a much sought-after feature that adds enormously to the appeal of cars, for example. Novel structures and colors, and effects such as flop and changeant can be combined to produce a unique image and appearance.
In the functional area, there is strong focus today on improving existing technologies and also on smart, such as self-healing, coatings. Self-healing materials automatically repair damage to themselves. Super absorbent polymers, for example, can seal cracks in concrete.
Coatings can be applied on almost all materials or substrates, including ceramics, concrete, glass, metal, plastic and wood.
Coatings are a crucial component in numerous industries
The numerous different sectors in which coatings play an important role include architecture and industry, architecture, automotive and transportation, and flooring and furniture.
Architectural and industrial equipment is characterized by large surfaces and irregular shapes. Technologies have been developed to enable coverage of surfaces that are difficult of access. The coatings are designed to provide protection against damage caused by heat and light, weathering and corrosion.
Architectural and decorative coatings provide color and function, depending on the particular parts of a building for which they are used – for example basements, roofs, ceilings, decks foundations or walls.
Automotive and transportation coatings require excellent properties in order to protect vehicles from scratches, weathering and extreme temperatures as well as from the harmful effects of UV radiation. Interior automotive coatings provide protection against the extremes of light and temperature encountered inside vehicles, while enhancing esthetics and conveying a sense of comfort and luxury. Today, as coating technologies advance, consumers have a greater choice of colors for interior trim and car seats, for example, than in the past.
Furniture and flooring can be made of a number of materials, including wood, metal and plastic. The choice of coating will depend on the substrate and the end use: indoor and outdoor applications, for example, might require different properties.
To prolong their life and protect them from the damaging effects of heat and light, coatings require additives for stabilization.
SONGWON develops, manufactures and supplies a comprehensive range of high-value, high-performance coating stabilizers (among those, products like benzotriazoles, BTZ and hydroxyphenyl triazines or HPT) for numerous substrates, including steel, wood, ceramics, special composites, plastic films and plastic parts used in the architecture and industrial, architectural and decorative, automotive and transportation, and furniture and flooring industries among others.
