The main raw material components used in powder coatings include: 1. Resins are the key component of powder coatings. The range of resins used is increasing steadily in an attempt to meet the more demanding needs of new market sectors. Thermosetting Powders Thermoplastic Powders Epoxy Polyvinyl Chloride Epoxy-Polyester Hybrid Polyolefins Urethane Polyester Nylon Polyester TGIC Polyester Acrylic Polyvinylidene Fluoride 2. Curing agents are used according to the type of resin system employed and the final properties required of the coating 3. Accelerators are used to increase the cure reaction rate 4. Pigments are generally solid particulate materials such as titanium dioxide or carbon black 5. Fillers are used to reduce the cost of the coating formulation and / or to improve specific properties such as flow, surface texture, lubricity, etc. Common fillers are barytes, calcite, mica, talc, whiting, and wollastonite 6. Extenders, such as aluminum silicate, are used to provide opacity and act as a filler 7. Degassing agents are particularly important in low-bake systems. They are used to eliminate / dissipate gas bubbles that may cause film porosity and embrittlement or poor finish 8. Dry Flow agents improve the free flow of powders within the production delivery systems 9. Flow agents enhance film properties and minimize/eliminate surface defects by improving the flow of the molten coating. Examples of flow agents include polyacrylates, silicones, surfactants, and fluorinated alkyl esters 10. Matting agents are used to reduce the gloss of the cured film 11. Texturing agents are used to control/enhance the gloss level of cured films 12. Rheological additives provide viscosity control to molten coatings for improved edge coverage or for textured surface effects 13. Waxes are added to the formulation to provide slip, hardness, scratch and mar resistance, and to act as free flow powders and anti-bridging agents in processing 14. Tribo-charging additives such as antioxidants and light stabilizers are frequently used in powder coatings. Depending on their composition, tribo-static powders require additives, such as HALS to improve their charge ability in addition to their light stabilization properties. 15. Heat Stabilizers are required to be thermally stable and non-volatile during high-temperature powder extrusion and curing processes (electric and direct-fired gas ovens), and to show no discoloration. Various classes of antioxidants have different thermal stabilization mechanisms. High resistance against UV degradation is necessary for all exterior applications. This is achieved through a synergistic combination of UV absorbers and HALS. The raw powder coating materials are generally mixed dry and then fed into an extruder for melt mixing. Once cooled, the extrudate is then chipped and ground into the final product. The chips are ground to a very specific particle size distribution depending on the application.

The acrylic is a water-based floor coating made of acrylic polymer emulsions. Meanwhile, the epoxy coating comprises a resin and polyamine hardener, making epoxy better. As a 100% resin product, it is more resistant and durable than acrylic. Following, pls check five key differences between both types of coatings. Usability If you want to focus on interior floor coating, epoxy coating is specially developed, while acrylic coating can be used on both exterior & interior floors. Also, epoxy is designed for areas prone to oil or chemical leaks. Abrasion-resistant The epoxy coating provides a long-wearing surface due to its being abrasion-resistant, unlike the acrylic coating. Finishing Epoxy coating provides a high gloss finish, while acrylic coating provides a more diverse option for finishing looks, ranging from matte to glossy. Besides, acrylic coatings are more rentable for decorative concrete where there is no heavy foot traffic. Acrylic works like a protective coating, and it does not penetrate the concrete. Affordability Affordability plays a deciding factor for any product, which applies when choosing between acrylic and epoxy. As mentioned before, as epoxy is more durable due to the resin, it increases the price. Besides, it has been shown that water-based solutions are cheaper than 100% solid epoxy resin products. Application It’s vital to know that epoxy lasts more time to dry than acrylic. Also, you should be careful with the application because water could damage the application if it is not well dry.There are some areas where you can use acrylic and epoxy: Acrylic Coating • Exterior surfaces like stamped concrete • Interior floors to make them resistant to staining Epoxy Coating • High traffic areas • Manufacturing facilities • Chemical containment areas • Garages and Kitchens

Looking at packaging printing inks, the more high-end, especially water-based printing inks, the stronger the printing characteristics and the narrower the application range. From ordinary batter starch, dextrin to shellac, casein, sodium lignin; from rosin-modified maleic acid resin to styrene-acrylic acid copolymer resin, and even the current polymer with core-shell structure and network structure Emulsion resins are all called water-based inks without exception. Water-based ink for folding cartons need to be formulated with moderately high gloss and good surface rub resistance. It has combined the characteristics of various packaging and printing materials in manufacturing experiment trial printing, production and application, and firmly grasped: ① It can make the ink have sufficient leveling, spreading and gloss on the printing material; ② The film-forming substance in the ink adheres the pigments and fillers to the substrate. And give the ink a stand-alone body without sticking; ③ Maintain and improve pigment dispersion and printability; ④ It has high efficiency wetting agent and abrasion resistance; ⑤ It can have sufficient printing resolubility, but it must have a certain degree of water resistance after drying. Changed the traditional ink and wash using pure water-soluble polymer compounds (such as casein, shellac, polyvinyl alcohol resin, etc.) as the ink binder, because it only relies on water to adhere and is not resistant to friction and water. The printing and gravure ink system uses acrylic, polyurethane and other water-based ink binders, which have changed from the past glycol ethers (which can metabolize harmful substances such as alkoxy acetic acid) to propylene glycol ether series (metabolism produces almost no The toxic 1,2-propylene glycol is finally decomposed into carbon dioxide and water, which has very low toxicity. There is also a non-toxic water-based ink that will be introduced into the market without an initiator water-based UV ink.
