Crusher Backing Compound

Epoxy Crusher Backing Compound is an ambient temperature curing, filler extended epoxy system used for the lining of cone crushers. The epoxy crusher backing compound is also suitable for the following ancillary applications: bonding, filling, fastening, or grouting of holding/fastening bolts.

Technical Information:

Product: Rotex  EP – 64F Epoxy Crusher Backing Compound is a two – part, ambient temperature curing, filler extended epoxy resin with good impact resistance and very low shrinkage.

Colour	Resin - Brown Hardener – Green
Mixing Ratio	By Weight - 100 Parts resin : 6.25 parts hardener. By Volume - 100 parts resin : 10 parts hardener.

Note:  Mix resin and hardener for 3 – 5 minutes. Use a spatula, or other flat-edged implement. Increase in temperature will shorten the working time, geltime and setting time. Decreases in temperature will extend the working time, geltime & setting time.

Specific Gravity@ 25 ºC	Mixed Compound 1.60 g/cm
Viscosity @ 25 ºC	Mixed Resin
Practical Working Time (Pot life)	8.5 kg @ 25 ºC = 10 – 15 mts.

Typical Cured Properties:

Hardness after 24 hours@ 25ºC	Shore D 80 – 90
Shrinkage after Cure	Maximum 0.5 %.
Elongation (Average)	1 %.
Tensile Strength	250 – 300 kg/cm²
Compressive Strength	700 – 900 kg/cm²
Heat Resistance	- 10 to100 +
Adhesion	To Cleaned and roughened metal and concrete – Excellent.

Chemical Resistance:  Excellent against water, oil, grease, detergents, diluted acids and alkaline. Resistant to solvents, aliphatic alcohols and aromatics. Against esters, ketones and chlorinated hydro-carbons, tests are recommended.

Water Absorption:  Immersion for 24 hrs @ 25ºC  in distilled water- maximum 2%.

Typical Properties: Easy Pourability and good penetration even at low temperatures. Minimal filler settlement in containers – easily mixable. Fast reactivity and outstanding mechanical properties. Good curing properties at lower temperatures.

Crusher preparation:   Block all cracks or gaps in the lining between the crusher and steel lining. If no adhesion is required, apply a grease or silicon – based release agent to the crusher bowl before casting.

Safety Precautions: Avoid direct contact of resin with skin. Use of hand gloves during handling is recommended. Splashes on the skin, if any should be removed immediately with suitable remover.
