Horizon Adhesive #HM225 EVA hot melt for perfect binding

Print & Finishing Solutions supplies Horizon Adhesive #HM225 for production perfect binders that run high-temperature EVA hot melt. HM225 is a white chip adhesive packed in a 44 lb carton, with a nominal operating temperature of 356°F. Before ordering, confirm the binder model, glue-tank configuration, setpoint, stock coatings, and spine preparation. HM225 cools quickly for routine production turnaround. Difficult digital stocks may need testing or another adhesive formulation.

FAQs

Which perfect binders can run Horizon HM225 adhesive?

HM225 is made for Horizon BQ perfect binders that run standard EVA hot melt. Many other EVA-equipped binders can use it, but check tank temperature, roller settings, and adhesive specifications before switching products.

What temperature should I use for Horizon HM225?

The published operating temperature is 356°F. Follow the binder manual and verify the glue temperature in the tank. The control-panel reading may differ from the adhesive temperature at the application roller.

Is Horizon HM225 an EVA or PUR adhesive?

HM225 is an EVA hot-melt adhesive. It cools and sets quickly, which works well for short-turn production and same-shift trimming. It does not match the coated-stock adhesion, flexibility, or heat resistance of properly processed PUR adhesive.

Will HM225 bind digitally printed and coated stocks?

Results depend on toner coverage, fuser oil, coating, grain direction, milling depth, and fiber exposure. Run page-pull and flex tests with the actual stock. For difficult digital work, compare HM225 with an EVA made for toner-printed sheets or with PUR.

How is Horizon HM225 packaged?

Print & Finishing Solutions supplies HM225 as white adhesive chips in a 44 lb carton. The chip format allows manual replenishment in compatible EVA glue tanks and premelters.

Can HM225 replace another EVA glue without cleaning the tank?

Do not mix adhesives unless the manufacturer documents compatibility. When changing formulations, drain and clean the system according to the binder and adhesive instructions. Mixed products can change viscosity, application weight, pot stability, and bond performance.

What should operators check when page-pull strength drops?

Check glue temperature, application thickness, spine milling, notching, paper grain, cover scoring, nip timing, and adhesive age. Record the settings and test a fully cooled book block before raising the temperature or application weight.

Where can Western U.S. print shops order Horizon HM225?

Print & Finishing Solutions supplies Horizon HM225 to commercial printers and in-plants across the United States. Include the binder model and current adhesive when requesting a compatibility check.
