Demand for Paints and Coatings to Decline from the Automotive Sector

The primary purpose of paints and coatings is to prevent corrosion. This corrosion prevention comes from two sources, first, with the materials used to manufacture the coatings, and second, by using certain solvents and heat treatments. Materials used to manufacture the coatings have varying levels of porosity, thickness, hardness, tensile strength, etc., and depending on these characteristics, the paints and coatings will adhere better to the surface. Heat treatments, often referred to as catalyzing or mechanical plating, increase the porosity, strength, and hardness of the material and make them more resistant to corrosion.

Paints and coatings have been the industry standard for all sorts of chemicals. Unfortunately, there are always accidents and catastrophes that can threaten the integrity and effectiveness of paints and coatings. Many industrial coatings have been classified as either "fireproof" or" Protective" based upon whether or not they contain an oil or water-based formulation. The food and drug industries also have their own stringent regulations and market.

There are several primary coatings on the market. However, the demand is expected to decline, especially from the automotive sector, owing to decreasing sales of automobiles due to Covid-19 pandemic. However, launch of novel products is expected to revive the market. The Paints and Coatings Expo in Japan is expected to witness the launch of novel types of primary coatings. The expo is slated for 23 - 25 June 2021 in Osaka, Japan.

Other types of industrial coatings include solvent evaporation paints and drywall paints. Solvent evaporation paints are highly absorbent paints containing volatile organic compounds (VOCs), which are carcinogens. Solvent evaporation paints also have excellent fire resistance properties, but some of these types contain toxic solvents that evaporate into the atmosphere at a relatively low rate. Drywall paints are applied directly to the surface and tend to last longer than solvent evaporation paints, but they can be chipped or damaged easily by water or air.

Paints and coatings also come in numerous liquid formulations, including oils, alkyds, and acrylics. These coats are used to provide resistance to abrasion, moisture, chemicals, and corrosion. Liquid coatings can be applied in a number of different ways. Some formulations are solid and cover a large area of the surface, while others are semi-viscous, which mixes with the air and form a protective layer that hardens under pressure and is then used as a sealant.

Chemists formulate paints and coatings with specific formulations according to their needs. Some chemicals and processes must be specially formulated, and often test samples are mixed with other additives to determine the right chemical reaction. Paints and coatings must also be allowed for time to cure before they are applied, which can take several hours. There are three different processes used to speed up the drying time: Stirling, buffing, and spraying.

Pregnancy Testing Devices are proving to be revolutionary tool with hassle-free testing and rapid results

Image
Pregnancy Testing Devices are medical devices that aid in identifying the potential of pregnancy. It is mostly used by pregnant women for determining the exact time they missed their periods. Pregnancy Testing Devices come in different types like basal body membrane technique (BBMT), digital analysis, embryo transfer method (ETM), ultrasonic Doppler microform method (UDM), and hysterosalpingogram (HSG). Pregnancy Testing Devices is also calling pregnancy test kits.  They can also be termed as basal body membrane technique test kits. Pregnancy test kits are available in various online stores at affordable prices. The most common one is kits for basal body membrane technique (BBMT) and digital analysis. BBMT uses a wet mount for conducting the test whereas digital analysis requires no dry mounts. Some of the other methods of analyzing pregnancy tests include determining the LH level, HCG level, sugar level, cervical mucus, and viral detection. A pregnancy test can also be used for d...

Liquid Crystal Polymers are witnessing wide range of applications as Industry Leaders in Japan Develop Novel LCP Products

Image
Liquid crystal polymers (LCPs) are a category of aromatic polymers that are extremely inert and unreactive and also highly resistant to fire. LCPs are mainly useful in mechanical and electrical parts, food containers, and also other applications where chemical inertness is necessary. They are also used in plug connectors, transmission system components, lamp sockets, pump sockets, and sunlight sensors. The most recent technology to emerge as one of the most sought after polymeric materials is the LCD or Liquid Crystal Display.  This technology is now used in almost every commercial production process from the initial manufacturing stage right through to the final display unit of an electronic display. Liquid crystal polymers are currently used in the construction industry and are widely available as a wide range of goods. Polypropylene, polystyrene, and polyimide are popular building material which use these compounds to make various products including insulation, plastic, insulati...

Polydimethylsiloxane (PDMS): A Member of Polymeric Organosilicon Compounds Used In Various Industries Due To Its Versatility and Properties

Image
Polydimethylsiloxane (PDMS) is a compound that is commonly used for the development of contact lenses, but it has many other uses as well. Surfactants and foaming agents are among the many things that are made from PDMS. Other uses include, the treatment of petroleum jelly and rubber. The chemicals used in the manufacture of cosmetics and medicines may also be derived from PDMS. The production facilities for PDMS in Europe are located in France, Germany and the U.K. In Germany, PDMS is classified as “slightly water polluting”. It was not that long ago that scientists thought there might be some connection between the use of polydimethylsiloxane in cosmetics and the development of allergic reactions. Scientists have since conducted studies and discovered that there actually are connections between the use of this chemical agent and the development of eczema and allergic reactions. The link between cosmetics and skin irritation and allergy is a result of the fact that the ingredients in...
