Film formation in waterborne latex coatings is not a process in which the resin first dissolves and then dries directly into a film. Instead, after water evaporates, the latex particles gradually approach one another, pack together, deform, coalesce, and finally form a continuous coating film. ...
In the early stages of drug discovery, researchers usually focus first on activity: whether a compound can bind to the target, inhibit enzymatic activity, or produce the desired effect at the cellular level. However, as a project enters lead optimization, the factors that limit further ...
Amides are among the most common functional groups in drug molecules. They can provide hydrogen-bonding interactions, connect different structural fragments, and help molecules maintain specific conformations through their relatively strong planarity. However, an amide is not always the optimal ...
Fluoropyridines can be divided into three positional isomers: ortho, meta, and para. For synthetic chemistry, these three isomers do not present the same level of difficulty. Ortho- and para-fluoropyridines can usually be obtained through well-established halogen-exchange reactions, commonly ...
The long-term storage stability of a waterborne pigment concentrate is outwardly reflected in whether the particle size increases again, whether sedimentation occurs, whether flocculation develops, whether viscosity drifts, and whether color development remains stable. At its core, it depends on ...
In small-molecule drug discovery, the value of a molecular building block depends not only on whether its structure is novel, but also on whether it can be effectively introduced into target molecules and provide well-defined variables for structural optimization.
Many personal and home care products encounter the same issue during development: they smell very fragrant from the bottle and have a noticeable scent during use, but after rinsing, towel-drying, air-drying, or standing for a period of time, the fragrance quickly weakens. Common solutions ...
Most coatings use resin as the continuous phase and typically exhibit high electrical resistance after film formation. For ordinary decorative and protective coatings, this insulating property is not necessarily a problem. However, in applications such as antistatic flooring, electronic-industry ...
When daily chemical products show a decrease in viscosity during summer, the issue should not simply be attributed to “high temperature.” An increase in temperature does reduce the viscosity of most liquid systems, but the extent of viscosity thinning mainly depends on whether the thickening ...
