Polyurethane is a new kind of organic polymer material. It is reputed as &ldquo and the fifth largest plastic &rdquo. Because of its excellent performance, polyurethane is widely used in many fields of national economy. What are the differences between waterborne polyurethane and oily polyurethane? Today, Xiao Bian came to tell you the difference between the two.
Difference between waterborne polyurethane material and oily polyurethane material
Introduction of waterborne polyurethane:
Water borne polyurethane is a new polyurethane system which uses water instead of organic solvent as dispersing medium. It is also called water dispersible polyurethane, water polyurethane or water-based polyurethane. Water borne polyurethane, with water as solvent, has the advantages of no pollution, safety, good mechanical properties, good compatibility and easy modification.
Waterborne polyurethane resin has gradually replaced solvent type, becoming an important direction of polyurethane industry development. Waterborne polyurethane can be widely used in coatings, adhesives, fabric coatings and finishing agents, leather finishing agents, paper surface treatment agents and fiber surface treatment agents.
The modified silicone resin into a series of polyurethane leather, polyurethane finishing agent, polyurethane adhesive, shoe material, polyurethane coating, printing ink, by contrast test engineers found that can solve all kinds of problems of waterborne polyurethane and oily polyurethane products.
Difference between waterborne polyurethane material and oily polyurethane material一：
The aqueous polyurethane chemical grouting material is light yellow, while the oily polyurethane plugging agent is dark brown. This is the two product intuitive, the most obvious difference.
Difference between waterborne polyurethane material and oily polyurethane material二：
The water borne polyurethane chemical grouting material has large packing capacity and large radius of penetration, which is suitable for sealing and protecting the shallow soil layer and surface layer of the water formation. And because water polyurethane chemical grouting material consolidation body elasticity is good, so it is most suitable for concrete dynamic joint seepage control, plugging.
The oily polyurethane chemical grouting material is commonly called &ldquo in domestic, and the &rdquo of the solidified material is strong, and the permeability is good. It is suitable for strengthening the foundation, protecting the forest and plugging the water. At the same time, the polyurethane polyurethane chemical grouting material has little elasticity, so it is more suitable for seepage prevention, leakage stoppage and reinforcement of concrete static joint.
以上关于Difference between waterborne polyurethane material and oily polyurethane material就简单介绍到这里了，希望对您有所帮助。更多资讯，尽在齐家网，敬请期待。
