Waterborne polyurethane adhesive is a kind of high-grade adhesive, with excellent flexibility, impact resistance, chemical resistance and wear resistance, the most important is its low temperature resistance.It has adsorption and chemical bonding effect on many kinds of materials. It can not only bond porous materials, but also bond smooth surface materials. It is widely used. Polyurethane adhesiv...
The most important application indexes of water-based adhesives in the packaging and printing industry mainly include four aspects: bonding strength, high/low temperature resistance, moisture resistance and viscosity holding.In practical application, defects such as weak adhesion and brittle degumming film are basically caused by the above four application indicators are not up to standard.In prac...
Water-based plastic composite ink is a product with water as the solvent. From the perspective of printing mode, water-based ink is not suitable for offset printing at present. Its main application fields are flexographic printing gravure printing and screen printing. Printing costs are related to the raw materials selected by ink manufacturers, such as the size of the molecular weight of the resi...
From the development of printing industry in developed areas of the future development track can be considered in China's packaging and printing industry to take the road of environmental protection is an inevitable trend, and the environmental protection of ink plays an increasingly important role.Although the stage has not yet established green ink or environmental protection ink discrimination ...
Water-based ink resin is suitable for intaglio printing ink. The ink coating prepared with this product has good film forming ability, quick drying, high gloss, high hardness and scratch resistance, good film forming ability on the surface of paper foil and good compatibility with water-based pigment. Application characteristics 1 Good film formation 2 Suitable for a variety of substrates, good ad...
Waterborne polyurethane fabric coating agent can give the fabric a good soft and plump feel and skin feeling, and the anti-wrinkle, anti-shrinkage, resilience and flexure of the coated fabric have been greatly improved, waterproof waterproof polyurethane fabric coating agent has become the fabric manufacturers and consumers favored object.So how does waterborne polyurethane work as a waterproofing...
Finally, ordinary glue products, ordinary glue products have a certain elasticity and softness, and have a good tensile length but tensile strength and strength is not very large, adhesion welcome you to consult, this is our email sales@sinogracechem.com
Waterborne polyurethane is often used in the preparation of waterborne coatings because of its excellent film formation and adhesion, excellent flexibility and wear resistance.However, water-based polyurethane dispersion contains a lot of surfactant, easy to produce bubbles, and because of the special properties of water-based polyurethane, it is necessary to use the characteristics of water-based...
Printing pressure has a great influence on printing quality.Maintaining an average and constant printing pressure in the effective printing area can not only make the printing ink uniform, small color difference, but also keep the size of the printing mark.It is feasible to achieve maximum flat flat printing printing pressure But because it is the manufacturing precision of printing plate flatness...
Surfactants are a large group of organic compounds, their properties are very characteristic, application is extremely flexible, extensive, has great practical value. Surfactants have been as emulsifier, detergent, wetting agent, penetrating agent, foaming agent, solvent, dispersant, suspending agent, cement water reducing agent, fabric softener, leveling agent, fixing agent, fungicide, catalyst, ...
Polyurethane sealant is widely used in civil construction, transportation and other industries: Applications in construction - filling and sealing of doors and Windows, glass, etc.; Applications in civil engineering - caulking sealing of expressways, Bridges and airstrips; Automotive applications - Assembly and sealing of Windows (mainly windshield). Polyurethane sealant has many excellent charact...
What is a coupling agent? Coupling agent is a class of substances with amphoteric structure, a part of their molecules coupling agent is a class of substances with amphoteric structure, a part of their molecules can be divided into groups and inorganic surface chemical groups reaction, forming chemical bonds; The groups can react with the chemical groups on the inorganic surface to form chemical b...
In the process of coating manufacturing, it is necessary to belong to the hydrophilic polar material Yan, fillers dispersed to belong to the hydrophobic non-polar material organic base material.In order to increase the affinity between inorganic matter and organic polymer, it is generally necessary to use coupling agent or other surfactants to treat the surface of inorganic matter, so that it chan...
Automobile seal strip is one of the important parts of the automobile, widely used in doors, Windows, body, seats, sunroof, engine case and trunk and other parts, with waterproof, sealing, sound insulation, dust, antifreeze, shock absorption, heat preservation and energy saving important role.The rubber flocking seal occupies a very important position in the automobile seal system. The rubber floc...
Coupling agent is a kind of material with two different properties of functional groups, the biggest characteristic of its molecular structure is that the molecule contains two groups with different chemical properties, one is an inorganic group, easy to react with the inorganic surface; The other is an organophile group, which can react with synthetic resins or other polymers or form hydroge...
Water-based adhesives have various kinds and different properties, which can adapt to the trend of environmental protection. The important properties of water-based adhesive are: solid content (non-volatile mass percentage), viscosity, emulsifier or surfactant total agent dosage, surface tension, pH value, particle size and distribution, film forming temperature, mechanical stability, etc.Com...
