Some types of biocides are disinfectants, insecticides, pesticides, fungicides, preservatives, and antiseptics. Biocides are important across almost every industry, working to deter the effects of potentially harmful things like insects, mold, rot, and pathogens. Biocides work to kill bacteria, control health risks, and prevent consumables from perishing. The biocide market is enormous in the U.S, with growth in the last decade. Biocides exist in the form of paints, coatings, and resins for use in industries in which the control of microbes and pests is necessary. Hospital walls and floors can use biocide paints to decrease the likelihood of mold, mildew, toxins, bugs, and other issues. Microbiocidal paints have the power to kill microorganisms that come in contact with the painted surface. High-performance paint biocides can keep mold, mildew, and algae growth away from important projects. view less

In order to give optimum protective and aesthetical properties most coatings should be smooth and without craters, pinholes, cracks, et cetera. Film defects can ruin coatings, and a huge amount of time and money is invested in preventing and resolving defects. Substantial savings can be made when knowledge, being both simple and available, is used. How to resolve a defect turns out to be logical as soon as the governing phenomena of the defect are known and understood. A wide variety of coating defects occur and in the following only a few of them are briefly discussed. view less

Cross-links can be ionic or covalent bonds between natural or synthetic polymer chains. In the chemical field, scientists typically use the term “cross-linking” to describe the process of bonding two polymers to define the differences between their physical properties. In the biological field, cross-linking is used to initiate protein-to-protein interactions. There are many kinds of cross-linkers and polymers available in chemical and biological settings. The cross-linking agent varies depending on the application. For example, calcium gluconate is a desirable cross-linker that controls biological microorganisms. This encapsulates biocontrol microorganisms in alginate beads with optimal survival and shelf life, according to researchers. Encapsulation via epoxidized linseed oil as a cross-linker works best for controlling the release of a liquid reactant in a matrix of reactive polymers. There are many different cross-linkers and encapsulation products depending on the application. view less

Several industries use encapsulation for a variety of different applications. One can encapsulate metal to optimize chemical reactions, and encapsulate metal surfaces to increase long-term corrosion protection. Encapsulation is also important for sealing off lead paint and protecting oil-soluble ingredients from oxidization. Encapsulation provides solutions to a wide range of problems. Microencapsulation also refers to the process of protecting oil-soluble ingredients against oxidization. Manufacturers use molecular encapsulation to mask tastes and odors, stabilize actives like light and temperature, increase the solubility of actives, and reduce volatility. Lead paint is highly toxic and is currently banned in households and other buildings in America. In homes built with lead paint (prior to the year 1978), encapsulation can solve the issue without replacing the paint. In this application, one can only use encapsulants approved by the State’s Register of Approved Products over lead paint. Encapsulation of lead paint is only effective as a barrier on surfaces in good condition, not those that are deteriorated or in high-traffic areas. Encapsulation of electronic parts and devices can lend protection from corrosion and abrasion. In the electronics industry, encapsulation can protect items such as circuit boards from moisture, dust, and harsh chemicals. view less

It is a synthetic material created by combining a polyhydric alcohol and an isocyanate through polymerization. Polyurethane creates tough coatings, strong adhesives, durable resins, and foams. Most polyurethane is heat resistant, although thermoplastic polymers are also available that can be molded by heat. Polyurethanes are unique from other polymers in that they have carbamate groups in their molecular structure. Polyurethane can come from a variety of materials, including stabilizers, monomers, and prepolymers. The addition of materials such as antioxidants can act as stabilizers to strengthen the polyurethane and give it customizable features like heat resistance. Stabilizers give manufacturers the ability to create polyurethanes that increase resistance to damage from light, temperature, oxidization, chemicals, and atmospheric contaminants. Manufacturers may also add colorants because the natural color of polyurethane is white. view less

Several industries, from food to chemical engineering, use encapsulation to repel undesirable factors such as moisture and oxidization. Using encapsulation coatings as repellents can make products resistant to extreme temperatures, abrasion, humidity, mold, and water . Using an encapsulation coating such as an epoxy adhesive can provide excellent protection in a variety of environments and circumstances. There are hundreds of different types of encapsulations and just as many combinations of ingredients to create a repellent. For example, repellents used on woods, may consist of chromated arsenicals, creosote, and pentachlorophenol (PCP). Newer wood preservatives may have ingredients like propiconazole (a fungicide), acid copper chromate, and alkaline copper quaternary (an insecticide). Encapsulation options for metal and cement surfaces will typically come in the form of water-based acrylic coatings that prevent corrosion. Hydrophobic repellents will protect surfaces and products from water, moisture, debris, and abrasions. Hydrophobic coatings are important for protecting wood, electronic devices, and other products from water damage. view less

Other materials that fall under the category of “resin” include acrylic, cellulose, and alkyds. Gel coat resins also exist, which are combinations of additives and base resins. Every resin has a unique purpose and properties that make it valuable across numerous industries. Most resins are flexible, versatile, strong, and resilient – making them important in manufacturing, automotive, construction, aerospace, and a number of other industries. Common products that utilize natural resins include: plastics, medicine, flavors, aromas, varnishes and coatings, printing inks, adhesives, insecticides, insulation, and stimulants. Synthetic resins have similarities to natural ones but with different chemical makeups. Synthetic resins and plastics are often interchangeable. There are two types of synthetic resins: thermosetting and thermoplastic. Thermosetting resins retain their shape permanently after the heating process. Thermoplastic resins, on the other hand, remain fluid after heat treatment and can undergo reshaping as necessary. Examples of synthetic resins include polyester, epoxy, and polyurethane. view less

It’s commonly found in substances such as quartz, as well as other living organisms. In certain parts of the world, silica is abundant in sand and is a raw material for ceramics, pottery, and earthenware. As one of the most complex groupings of materials, silica can exist as a compound of several natural minerals or as a synthetic invention. Silicate minerals are some of the most ubiquitous substances in the world, found in mica, quartz, feldspar, and pyroxene. Its applications are abundant, from structural engineering to food and pharmaceuticals. Because of its cost effectiveness, silica is used as an “extender” in many paint products. This means it acts as a filler substance and can also flatten the paint. In paints used for architectural purposes, silica provides durability and resistance against exterior factors likes dirt and weathering. In addition, silica can increase brightness and dimensionality of paints that are used for wide scale purposes. Silica is a flexible compound that serves a range of uses across several industries. One of the most widespread uses for silicon dioxide is in the construction industry. Silica-laden sand is often used in sandcasting. It’s an ideal match for structural purposes because of its comparatively high melting point. view less
