PUR Hot Melt Adhesive for Bookbinding Applications

Application Overview

SINOHESIVE PUR hot melt adhesive for bookbinding is designed for the binding of standard books, magazines, brochures, dictionaries, and other thick-volume publications.The adhesive provides excellent adhesion to common substrates such as paper and can be applied using dedicated moisture-resistant hot melt adhesive equipment through roller coating, spray coating, or slot-die coating processes.It provides reliable support for book spine adhesive application, cover attachment, and high-speed bookbinding production.

Low VOC & Environmentally Responsible

The product uses a 100% solids system.According to technical data, it is designed with zero VOC characteristics and excludes harmful substances such as aldehydes, ketones, benzene, and hydrocarbons.The system supports bookbinding projects where manufacturers place emphasis on printing and binding workplace conditions, finished-product odor, and material safety requirements.

Key Benefits

Suitable for Various Book Types and Spine Structures

The adhesive is suitable for binding standard books, magazines, brochures, dictionaries, and other thick-volume publications.It supports different page counts, paper types, and book spine thicknesses for various bookbinding applications.

Tough and Durable Adhesive Film

After curing, the adhesive film provides toughness, durability, and good resistance to heat, cold, water, and chemicals.According to technical data, it can withstand temperatures up to 155°C and low temperatures down to -35°C, supporting reliable bookbinding performance during transportation, storage, and daily use.

Suitable for High-Speed Bookbinding Production

The adhesive provides fast curing performance and can be used on high-speed production lines.It also maintains stable viscosity in the adhesive tank for extended periods, helping ensure consistent adhesive application during continuous bookbinding operations.Actual production speed and coating performance should be verified according to book structure, equipment conditions, and ambient temperature.

Suitable Open Time for Cover Attachment

The adhesive provides an open time of approximately 5 minutes, allowing sufficient working time for spine coating, cover attachment, and pressing.Actual open time may vary depending on application temperature, adhesive thickness, paper temperature, thermal conductivity, and ambient conditions.

Supports Multiple Coating Methods

The adhesive can be applied through roller coating, spray coating, or slot-die coating.The recommended application temperature is 100–130°C, and processing parameters can be adjusted according to bookbinding equipment, coating method, and production requirements.

Application Support for Your Bookbinding Project

Final bookbinding performance can be affected by paper type, book block thickness, paper moisture content, spine preparation, adhesive amount, equipment temperature, pressing pressure, and curing conditions.
