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.

It’s no secret that the flexible packaging market is growing and growing fast. Many consumers and packagers are turning to flexible packaging because of its light weight, convenient features, and endless customization options. Heat seal and Cold seal are both used in a variety of flexible packaging applications. They each have difference characteristics and work best for specific product needs. Do you know the difference between the two and which works best for your application? Read on to find out. Heat Seal Packaging Both surface printed inks and lamination inks can also be heat sealed. In this instance, a heat sealable film is used or a heat sealable coating is used to combine two films by applying heat to achieve the seal. Sealing temperatures and pressures can vary so when formulating these types of inks, it’s important to know and test the inks under these sealing conditions. A typical sealing specification maybe 350 degrees Fahrenheit for half a second at 40p.s.i. Heat sealing is used for joining thermoplastic films, typically less than0.5 mmthick. There are two main types of heat sealing: hot-bar welding and impulse welding.Hot-bar welding and impulse welding have found applications in a number of industrial sectors, but are most widely used in the packaging industry for sealing bags, films, and containers made from thermoplastics. This includes plastic pot and tray sealing for food packaging applications. Cold Seal Packaging Cold-seal packaging is a complex package. It often involves two films, one reverse-printed with the brand owner’s graphics, and a second that provides the barrier to protect the product inside. These two films are then laminated together to produce a single inseparable web. From there, the cold seal is applied on the inside surface of the web in a pattern registered/aligned with the graphics on the outside of the web. Many temperature-sensitive confectionary items (e.g. chocolate) are packaged and sealed using cold seal adhesives. These surface printed constructions consist of a surface printed ink and a cold seal release lacquer (CSRL), which prevents the printed ink from offsetting against the cold seal glue when in the printed roll. Inks for cold seal packaging should not be formulated with any kind of fatty amide or PFE waxes as these can “poison” the cold seal adhesive if left in contact with the adhesive for any length of time in the printed roll.
