Henkel's Loctite® Foaming Polyurethane Protects Hydraulic Roof Supports from Longwall Mining Debris

Self-Extinguishing, Low-Odor Foam Fills Pocket and Hydraulic Cylinder to Reduce Equipment Damage

Rocky Hill, Conn. -- For hydraulic roof support equipment used in longwall mining, Henkel Corporation has introduced Loctite® MR5898™ Foaming Polyurethane, a pour-in-place foam material designed to bond to pockets and hydraulic cylinders. By foaming up to fill entire cavities and adhering to edges, this innovative foam effectively blocks out  debris, particulates, teeth or tools that might damage the equipment, yet is flexible enough to allow free movement of the hydraulic leg.

Loctite® MR5898™ Foaming Polyurethane replaces precut foam inserts that allow debris to migrate into cavities through gaps between inserts and equipment edges. This self-extinguishing, low-odor foam is  intended for use underground and in confined spaces. The two-part formula begins to foam a few minutes after mixing and becomes tack-free within minutes of pouring. The flexible cured foam can be easily cut or trimmed using a serrated blade.

Use of Loctite® MR5898™ Foaming Polyurethane on hydraulic roof supports ensures proper functioning of equipment, reduces unplanned downtime and prevents costly component replacement. Workers spend less time cleaning pockets and cavities, and do not need to inventory or store spare foam inserts. The foaming polyurethane product is available in convenient kit sizes.
