What are the differences between acrylic resins used in coatings and adhesives
- 2026-01-22 16:56:57
- admin
Acrylic resins used in adhesives and acrylic resins used in coatings differ in the following aspects: Performance Characteristics Acrylic Resins for Adhesives High Bonding Strength Requires strong adhesion between different materials, requiring rapid curing and sufficient cohesive and adhesive strength. For example, α-cyanoacrylate adhesives can cure in seconds for rapid bonding. Good Flexibility ...

Basic Knowledge of Waterborne Polyurethane Emulsion Synthesis
- 2026-03-12 17:02:25
- admin
01 Polyurethane The structure of polyurethane is formed by the reaction of polyisocyanates (e.g., diisocyanate OCN-R-NCO) and polyols (e.g., diol HO-R-OH), where urethane segments are repeating structural units. Polyurethane structures have structures similar to amide and ester groups; therefore, the chemical and physical properties of polyurethane are between those of polyamides and polyesters. S...

What is the difference between pure acrylic emulsion and acrylic emulsion
- 2026-04-13 18:08:26
- admin
In the coatings industry, pure acrylic emulsion and acrylic emulsion (typically meaning styrene-acrylic) are two common waterborne binders. Their main differences lie in composition, performance, and application. 1. Composition Pure acrylic emulsion: Made from 100% acrylic monomers (e.g., butyl acrylate, methyl methacrylate). Acrylic emulsion (styrene-acrylic): Copolymer of styrene and acrylic mon...

Why Are Some Waterborne Polyurethane Dispersions Milky White While Others Are Translucent
- 2026-07-16 15:53:46
- admin
Waterborne polyurethane dispersions, commonly known as PUDs, may appear milky white, translucent, or slightly bluish in the liquid state. This difference is mainly related to particle size, particle size distribution, and how strongly the dispersed particles scatter visible light. In general, milky dispersions scatter more light, while finer dispersions allow more light to pass through. However, a...

How to Choose a Waterborne Polyurethane Dispersion for Industrial Glove Coatings
- 2026-08-11 18:51:37
- admin
As global environmental regulations such as EU REACH and OEKO-TEX® Standard 100 become increasingly stringent, traditional solvent-based PU systems face growing restrictions in protective glove manufacturing. With advantages such as low VOC emissions and no DMFa residue, waterborne polyurethane (WPU) emulsions are rapidly becoming a key choice for glove manufacturers transitioning from solvent...

How Do Resin Films That Are Too Soft or Too Hard Affect Textile Printing and Coatings
- 2026-09-30 15:28:08
- admin
The softness or stiffness of a textile resin film affects fabric feel, blocking resistance, and the ability of a print layer to withstand rubbing and deformation. A film that is too soft or too hard for its application may affect the finished textile during processing, storage, and use. “Too soft” and “too hard” depend on the intended application. Prints on soft clothing fabrics and backcoatings t...
