What is the difference between water-based polyurethane and oil-based polyurethane?

Waterborne polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy due to its excellent performance. There are water-based polyurethane and oil-based polyurethane in polyurethane. Today, ZHEJIANG RUICO ADVANCED MATERIALS CO., LTD. will tell you the difference between the two.

Waterborne polyurethane is a new type of polyurethane system that uses water instead of organic solvent as a dispersion medium, also known as water-dispersed polyurethane, water-based polyurethane or water-based polyurethane. Water-based polyurethane uses water as a solvent, and has the advantages of no pollution, safety and reliability, excellent mechanical properties, good compatibility, and easy modification.

The water-based polyurethane resin has gradually replaced the solvent-based, and has become an important direction for the development of the polyurethane industry. Waterborne polyurethane can be widely used in coatings, adhesives, fabric coatings and finishes, leather finishes, paper surface treatment agents and fiber surface treatment agents.

A series of modified silicone resins are introduced into polyurethane leather, polyurethane finishing agents, polyurethane adhesives, shoe soles, polyurethane coatings, and inks. all kinds of problems.

The water-based polyurethane chemical grouting material is light yellow, while the oil-based polyurethane plugging agent is dark brown. This is the most obvious difference between the two products.

The water-based polyurethane chemical grouting material has a large amount of water and a large penetration radius, which is suitable for plugging and gushing water in dynamic water formations, and for the consolidation and protection of shallow soil and surface layers. And because the water-based polyurethane chemical grouting material has good elasticity of the consolidated body, it is most suitable for seepage prevention and plugging of concrete dynamic joints.

Oil-based polyurethane chemical grouting material is commonly known as "cyanide coagulation" in China. The consolidated body formed by it has high strength and good permeability. At the same time, the oil-based polyurethane chemical grouting material has small elasticity, so it is more suitable for the anti-seepage plugging and reinforcement of concrete static joints.
