An Overview of Alkyd Resins, · Alkyd coatings are typically sold in three classes: long, medium, and short. These terms represent the oil length in the resin. Alkyds are also modified with phenolic resin, styrene, vinyl toluene, acrylic monomers (to make them dry more quickly), and .ADDITOL® VXW 6208, · ADDITOL® VXW 6208 by allnex is a polymer non-ionic dispersing additive for grinding inorganic and organic pigments in water or in waterborne alkyd resin, acrylic, epoxy and urethane emulsions. The binder-free pigment paste is used in gloss and silk finish emulsion paints.PET Processing, · In extrusion, most PET is processed into sheet for food packaging applications. The PET sheet or PET film is thermoformed into products such as drinking cups, trays, clam shell containers and the like. rPlanet Earth looks to disrupt the plastics recycling industry ...How to Identify Different Types of Plastic, · The production of plastics begins with the distillation of crude oil in a refinery. This step separates the heavy crude into groups of lighter components, called fractions. Each fraction is a mixture of different hydrocarbon chains, which differ in terms of the size and structure of their molecules.Catalyst for Coatings, · Read on to know how catalysts in paints enhance the polymerization of resin, strengthen the dry film and deliver better quality coatings. Many coating systems such as high solids, specific waterborne, urethane, amino systems and other 2 components require a high reactivity, low viscosity resins and crosslinkers to achieve a perfect curing, especially in the fields of industrial coatings ....
Epoxy Resin: Types, Uses, Properties & Chemical Structure, · Get detailed on Epoxy Resin, a versatile advanced thermoset. Explore its key properties, chemical structure and uses in high-end structural applications. The oxirane group of an epoxy monomer reacts with different curing agents such as aliphatic amines, aromatic ...Recycling Polyethylene Terephthalate, · Recycled polyethylene terephthalate is known as RPET, and it is the most widely recycled plastic in the world. According to PETRA, the PET Resin Association, the U.S. recycling rate is about 31% in 2012, while it is 52% in the European Union.In 2016, the U.S ...The carbon fiber process, · Once the epoxy resin is added to the carbon fibers it is wound up on large rolls: the carbon fiber prepregs. In order to prevent the carbon fiber prepreg from slowly reacting and thus hardening, the prepreg ideally should be stored at minus 18 degrees Celsius (0 degrees Fahrenheit).Saponification Definition and Reaction, · Saponification is the name of the chemical reaction that produces soap. In the process, animal or vegetable fat is converted into soap (a fatty acid) and alcohol. The reaction requires a solution of an alkali (e.g., sodium hydroxide or potassium hydroxide) in water andTypes of Solder Flux, · Flux remains on the surface of the metal while you're soldering, which prevents additional oxides from forming due to the high heat of the soldering process. As with solder, there are several types of flux, each with key uses and some limitations..
How Is Crude Oil Turned Into Plastic?, · Naphtha and the other crude oil components used for plastic production are then further processed. One of these processing steps is known as polymerization, which uses ingredients like ethylene to convert the chemical structure of the oil fractions, creating long, repeating chains of molecules known as polymers.What Is the Relationship Between Flow Rate and Viscosity?, · Predictions of flow rate are possible when the viscosity and forces known are involved, as long as the fluid is not compressible and the flow is laminar. This means that the molecules of fluid flow in straight lines parallel to the walls of the pipe or other channel.
