Black Bros. Hot Melt Adhesive Spreaders are built to handle the increasing market demands for both reactive hot melt adhesive and polyurethane hot melt adhesive (RHM/PUR) applications. The RHM-775 Hot Melt Adhesive Spreader is equipped with the necessary features to accommodate RHM/PUR materials: rugged steel frame, drive components on one end, heat connections on the opposite end, easy access to the roll ends for maintenance, large diameter rolls with heavy duty wall thickness, easy roll change, safety glass shielding for visibility, and vent or port for vapor control.

The oil heating unit mounts on the same base as the machine and is sized to meet your needs. Standard units are available from 32″ (812 mm) through 74″ (1880 mm) capacity. Units of 74″ (1880 mm) to 128″ (3250mm) can be designed and manufactured to customer specifications.

* Bulk melt or drum unloader units are also available. Black Bros. can also make arrangements to connect the hot melt adhesive supply with our liquid level feature to provide a precise and uninterrupted supply of hot melt adhesive.


Hot melt adhesives come in many types, for a variety of uses, here are the most common products:

Ethylene-Vinyl Acetate (EVA) / Thermoplastic polyurethane (TPU) / Polyamides (PA)
Polyurethanes (PUR) / Polyethylene (PE) / Polyolefins (PO) / Pressure Sensitive (PSA)

Hot melt adhesive technology has opened up the door to many manufacturers for quicker, stronger, more flexible applications. The following reasons are reasons for your manufacturing process to look at PUR (Poly Urethane Reactive) hot melt adhesives:

  • A PUR hot melt is the most versatile adhesive manufactured today

  • PUR’s can be formulated for virtually any substrate and laminate

  • PUR’s work well with dissimilar substrates/laminates

  • There are extremely high green strengths (initial bond) in the laminated product

  • Panels can be processed further without long staging times

  • There are typically no volatile ingredients in the formulation of PUR’s – No VOC’s

  • The amount of adhesive you spread at application will be the same amount present after curing

  • PUR adhesive offers an exterior grade glue line, resistant to water and temperature changes

What is Lorem Ipsum?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
