"Non-stick pan" is a very common pot in the kitchen, because in the process of using less oil consumption, less smoke, but also not easy to paste the problem, so it is welcomed by many people. In recent years, however, there have been more and more controversies about non-stick pans: Some people think that non-stick coating will produce toxic substances, can not be used for a long time; Some peopl...
I.Overview: Refilm process is widely used in all kinds of packaging, small to medicine box, artifact box, large to outer packing boxes and various product packaging.The current recoating technology includes precoating, dry recoating and wet recoating.Wet composite uses water-soluble adhesive cold paste process. Dry composite traditional composite film process is to apply solvent-based adhesive dir...
Choice of water-based adhesive Application index Some packaging and printing enterprises reflect that some water-based adhesives will degummy soon after gluing; Viscosity is not stable, sometimes bond firmly, but sometimes not bond; It works well in hot weather, but it doesn't work in cold weather.In fact, this is due to the lack of understanding of water-based adhesive application indicators. The...
Acrylic acid Important organic synthesis raw materials and synthetic resin monomer Acrylic resin is an important organic synthesis raw material and synthetic resin monomer, is a very fast polymerization rate of ethylene monomer.Is the simplest unsaturated carboxylic acid, consisting of a vinyl group and a carboxylic group. Most of them are used to manufacture methyl acrylate, ethyl ester, butyl es...
Application Acrylic emulsion is a kind of emulsion with wide applicability for construction. It can be used as a new chemical material for repairing steel structure concrete of hydraulic construction, port construction, highway, bridge, metallurgical chemical industry (urea chloro gangue) and other industrial civil buildings, such as seepage prevention, corrosion prevention and antifreeze. Cl...
1.The role of acrylic resins in photocured inks.Acrylic resin is widely used in the manufacture of photocuring inks because of its unsaturated property and polymerization reaction under the action of ultraviolet light.It and other substances, such as polyether, carbamate, polyester, epoxy resin, modified epoxy resin, poly caprolactam copolymer, can be used as a photocuring ink resin component. 2.T...
Polyurethane is the short form of polyurethane (PU). It is a block polymer formed by addition polymerization. It is a polymer compound with flexible and elastic polyether or polyester as soft segment and rigid and hard carbamate as hard segment. It contains a considerable number of ammonia ester bonds. Waterborne polyurethane has been successfully applied in the textile printing and dyeing industr...
Water-based adhesion enhancer Product introduction Water-based adhesion enhancer, a water-based chlorinated PP acrylic emulsion, used to improve the adhesion effect of water-based paint and ink on polypropylene (PP) material. Suitable for PP substrate, can do bottom, surface coating paint. Product specifications Composition: acrylic modified emulsion Appearance: Milky white viscous liquid Non-vola...
The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...
Water - based ink is also known as water - based (oil) ink, referred to as ink.Water-based ink is made of water-soluble or water-dispersed polymer resin, colorant, surfactant and other related additives through chemical process and physical processing. Water - based ink containing a small amount of alcohol water as solvent, ink stability.Therefore, it is especially suitable for food, medicine and ...
Printing ink according to the plate type is mainly divided into relief ink, lithographic ink, gravure ink, screen printing ink four categories According to its own characteristics can be divided into two categories of water-based ink and oily ink So what is water - based ink and oil - based ink? What's the difference? Usually see a lot of books, albums and other paper printed matter are used ...
Water-based viscosifying emulsion plays a very important role in water-based acrylic pressure sensitive adhesive, which can improve the bonding strength and initial adhesion of pressure sensitive adhesive on high and low energy surfaces, so as to achieve the best balance point, and can improve the application range and grade of pressure sensitive products. Today, we will take you to understan...
Water based adhesive Water-based adhesive refers to the water-soluble polymer dissolved into appropriate concentration of aqueous solution, or insoluble polymer dispersed into micro-particles (emulsion) in water with the help of surfactant in the general term of adhesives;In simple terms, adhesives made of materials that can be dispersed or dissolved in water are aqueous adhesives and are often re...
Environmental protection pressure has prompted some traditional solvent-based products to gradually withdraw from the market and replace them with water-based, high solid content, powder products, etc.Waterborne polyurethane, as an important member of waterborne products, is facing unprecedented development opportunities with its unique excellent properties.In addition to the leather industry, it ...
With the continuous improvement of people's demand for life, glue and adhesive products are also advancing with The Times and constantly upgrading to meet people's needs. The emergence of removable glue greatly satisfies this phenomenon, so what is removable glue? What are the characteristics of removable glue? Removable adhesive is a new type of environmentally friendly synthetic material, the ap...
