Crusher Backing Compound is polyurethane based, cold pouring protective backing compound intended primarily for use in gyratory and jaw crushers, mill-liners, and other similar equipment with surfaces exposed to continuous wear.

• It is a two component polyurethane based compound that hardens by chemical reaction after mixing.
• Crusher Backing Compound bonds well to grease free metal surfaces.
• It is faster, easier and safer to use than molten metal, and is easily mixed and poured to produce a backing of high compressive, tensile and flexural strength, with excellent chemical and electrical resistance.
• It cures quickly to keep maintenance downtime as low as possible.

Provides a cushion for the abrasion wear and tear of metal surfaces of mining and quarrying jaw crushers and mill-liners. It can also be used for for the backing of cast mills and shell liners. It is ideally suited for filling worn cavities, preventing bolts from loosening and stopping bolt-hole leakages.

• When Crusher Backing Compound is exposed to heat or direct flame, e.g. from a cutting or welding torch, toxic fumes may be evolved. These should be contained. The use of breathing apparatus under such circumstances is therefore a necessity.
• Keep carton and tins upright.
• It is moisture sensitive. Store under cool, dry, well-ventilated conditions, ideally off the ground. Keep containers tightly sealed as the components may otherwise absorb moisture from the air, seriously impairing the performance of the compound.
• Prolonged exposure to temperatures in excess of 40°C must be avoided. Stored under the correct conditions.
• It is a liquid polyol cured with iscyanates, which are potentially toxic. Although of minimal irritant potential, avoid direct contact of the Crusher Backing Compound resins with eyes, skin and mucous membranes and avoid inhalation of vapours.
• Whenever working with Crusher Backing Compound, good industrial hygiene should be observed; protective gloves, safety goggles and overalls should be worn.
• Work only in well ventilated environments.
