Method and dose of Disperse Agent (Using in Coating&inks): The dose of the Disperse Agent is small, and the Disperse Agent cannot demonstrate its advantages, and Over-dose can also affect the stability of the grinding. This is mainly because the superfluidly applied Disperse Agent cannot extend the solvated chain of the Disperse Agent on the pigment surface, and a large amount of loose Dispers...
Principle of Dispersant (Using in Coating): 1. In Mechanical method, the most basic purpose of pigment dispersion in the medium is to disperse lipophilic concentrated particles due to drying during pigment manufacturing. As the fineness of the particles decreases, the exposed surface area of the particles increases, which improves the optical properties of the pigment, such as coloring properties,...
China and the United States signed the first-phase economic and trade agreement on January 15, 2020. Foreign media said that the agreement has suspended the trade war between the two economic giants and is good news for the world. Among them, many US tariffs on Chinese pigments, resins and plastics appear to have remained unchanged. During a signing ceremony at the White House, U.S. President Trum...
Status of global hot melt adhesives, how is the Chinese hot melt adhesive market? Speak with graphic data of World and China Hot melt adhesives ! 1.Hot melt adhesives-global demand ratio by region 2. Hot melt PA adhesives - Proportion of global applications China Hot Melt Adhesive 1. Sales volume of hot melt adhesives in China in 2019 2. China's Hot Melt Adhesive Export Statistics, 2011-2019
Generally, for Hot melt Polyamide adhesives, Melt Viscosity means the resistance generated by the liquid when it is flowing, that is the resistance generated when painting. The number expressed in a certain unit is the melt viscosity.The unit is 1800~3200 cps/mPa s at 190 degree celsius. 1. High viscosity, poor fluidity; low viscosity, better fluidity. 2. There is no absolute relationship between ...
A polyurethane resin (commonly abbreviated as PU) refers to a class of polymers comprising a characteristic of a carbamate in the main chain. This polymer material is widely used in industrial applications such as adhesives, coatings, low speed tires, gaskets and automotive mats. In the daily life, polyurethane is used to make different foams and plastic sponges. Polyurethanes are also used ...
High viscosity soluble polyamide resin is a chemical raw material with excellent performance and can be divided into two categories according to its properties: non-reactive or neutral polyamide and reactive polyamide. Neutral polyamides are mainly used in the production of inks, heat-sensitive adhesives and coatings. Reactive polyamides are suitable for epoxy resin curing agents and thermose...
Why is the role of high softening point polyamide resin very large? This will benefit from its own advantages. Polyamide has good comprehensive properties, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubricating properties, and has low friction coefficient, certain flame retardancy and easy processing. It is suitable for filling w...
High gloss co-solvent polyamide resin is a polycondensation type polymer compound having a CONH structure in a molecule, which is usually obtained by polycondensation of a binary acid and a diamine. The most prominent advantage of co-solvent polyamide resin is that the softening point is particularly narrow, unlike other thermoplastic resins, which have a gradual cure or softening process w...
