Antifreeze is essential during the colder months due to its main function of regulating the temperature of a car’s engine. This important additive helps to prevent cracking in the engine components when the water inside the engine freezes during cold months. During the summer months, it helps cool down the engine to prevent overheating. Antifreeze was commercialized in the 1920’s... Read more »
Formulation 101: Plastisol Polyvinyl chloride (PVC) plastisols are liquid dispersions of fine PVC resin particles in a liquid plasticizer. When heated, the mixture undergoes gelation and fusion, resulting in a flexible, durable solid film or molded product. Due to their versatility, PVC plastisols are widely used in coatings, flooring, automotive parts, toys, textiles, adhesives,... Read more »
Metalworking fluids (MWFs) are essential in machining and metal-forming processes, providing lubrication, cooling, and corrosion protection. A well-formulated metalworking fluid enhances tool life, improves surface finish, increases production rates, and maintains workplace safety. This article outlines the key components and formulation process for a basic metalworking fluid. Understanding Metalworking Fluid Types Metalworking fluids are categorized... Read more »
Coatings have been around since ancient times by using sap, berry juices and eggs. In 1880, Sherwin Williams produced the first gallon of premixed paint and since then the industry has been growing into a multibillion-dollar industry. The main markets for coatings are architectural, automotive, marine, industrial and specialty. Within these markets the typical coating... Read more »
The first use of grease dates back to ancient times, when man first used animal fats and vegetable oils to reduce friction. Analysis of these crude lubricants shows that lime was sometimes mixed in as a thickener, making this the first complex grease. The science of lubricating technology has come a long way since ancient... Read more »
PVC is often used for electrical cable jacketing due to its excellent electrical insulating properties and dielectric constant. PVC is commonly used in low voltage cable (up to 10 KV), telecommunication lines, and electrical wiring. Basic formulation for the production of PVC insulation and jacket compounds for wire and cable is generally composed of the... Read more »
