The hot melt film formed is very tough and flexible and is highly visible on the rollers aiding the binding teams to accurately control coat weight.
Applications & Uses

- Compatible Substrates & Surfaces
- Application Instructions
- Application temperature: 130°C
- Open time (relative): medium/slow
- This product is suitable for most perfect binding applications. It can usually be applied without a primer. Typical application depths of the adhesive film should be between 0.5 and 1.0mm. The adhesive should be applied at approx. 130°C to a dust free spine. Spine preparation optimizes bonding performance especially with difficult papers.
- With cross grain papers the temperature can be raised to a maximum of 150°C to improve the bond. An ideal spine preparation should have notches of 0.5mm to 1.5mm depth and 4 - 5mm. The grinding depth of long fibrous papers may be less.
- The ideal coating and spine preparation depend to a great extent on the paper quality, size, weight and direction of the specimen fiber, cover and back lining material.
- The optimum application temperature must be adjusted to the application conditions, especially machine speed, distance and time from point of adhesive application to cover casing in and room temperature. If only a small quantity of hot melt is required and there are long machine standstills during a shift, the temperature in the pre-melt tank should be reduced to at least the softening point of the adhesive to avoid product degradation.
- Recommended Processing methods and temperatures:
- One-Shot: Primer between 130°C and 150°C
- Two-Shot: Top-Coat between 120°C and 140°C
- Cleaning Instructions: We recommend using a solid hot melt cleaning agent for applicators and adhesive tanks, and a liquid wipe-on or cold soak cleaning solution for machine parts.
- Typical Applications
- Suitable for single shot binding on automatic binding machines at high speeds and low application temperature (e.g. manufacture of catalogs, telephone directories and magazines).
- This product is also suitable for two-shot binding acting as the primer itself or with another dedicated grade.
- Approved Substrates
Standard paper stocks used for the applications listed. Difficult papers (for example coated paper, cross grain, etc.) The temperature of application needs to be on the highest level.
