There are various types of leather adhesives, which are mainly classified based on their chemical composition, solvent type, and application scenarios. From the perspective of chemical system, polyurethane adhesive has become a regular customer on the industrial assembly line because its molecular chain contains highly active groups, which can form excellent chemical adhesion with a variety of porous or smooth materials such as leather, foam, wood, etc. And water-based acrylic adhesive uses water as the dispersing medium, without solvent addition, which reduces the emission of volatile organic compounds from the source and meets the current demand for green environmental protection.

In terms of application forms, leather glue can be divided into manual brushing type, mechanical roller type, and spray glue type. Due to its uniform spraying, rapid drying, and large spraying area per unit weight, spray glue exhibits extremely high construction efficiency in scenarios such as sofa sponge bonding and large-scale leather wrapping. In the field of automotive interior modification, there are extremely strict requirements for environmental protection and odor. Low odor and high weather resistance water-based polyurethane adhesive has become an ideal choice. It can withstand the extreme temperature test inside the car, ensuring that leather seats and dashboard soft packages do not fall off or become brittle during long-term use.

In addition, for some special needs that require later adjustment or seamless removal, leather back adhesives with pressure-sensitive properties have also been derived, providing more possibilities for personalized customization and repair.
