What are the types of crosslinking agents

What are the types of water-based adhesives classified?

1： According to the raw materials of isocyanates, they can be classified into aliphatic, cycloaliphatic, and aromatic types. According to specific raw materials, it can also be subdivided into TDI type, MDI type, and HDI type

2： According to the properties of hydrophilic groups and the presence of ionic groups on the polyurethane molecular chain (polarity of the ionic chain), waterborne polyurethane can be divided into anionic, cationic, non-ionic, weakly cationic, anionic, cationic containing, also known as ionic polymer waterborne polyurethane.

3： Waterborne polyurethane can be divided into polyurethane lotion, polyurethane dispersion and polyurethane aqueous solution according to product appearance, among which polyurethane lotion and dispersion are most widely used in practice.

The above is the classification of water-based adhesive types.
