Loctite ® Nordbak ® <strong>Backing</strong> <strong>Materials</strong> —<br />
industry leaders with proven performance<br />
for over 30 years.<br />
<strong>Crusher</strong> <strong>Backing</strong> <strong>Materials</strong><br />
Loctite ® Nordbak ® <strong>Backing</strong> Material<br />
• 100% solids epoxy compound for backing wear<br />
plates in cone crushers and grinding mills<br />
• Provides high compressive strength and<br />
impact resistance<br />
• High volumetric stability eliminates gaps<br />
between liners<br />
• Nonfl ammable<br />
• Pourable compound requires no melting or<br />
special equipment<br />
Loctite ® Nordbak ® High Impact<br />
<strong>Backing</strong> Material<br />
• Excellent resilience while retaining high<br />
compression and tensile strengths<br />
• Maintains all other features of regular Loctite ®<br />
Nordbak ® <strong>Backing</strong> Material (heat distortion<br />
temperature, ease of mixing and pouring)<br />
Loctite ® Nordbak ® Accelerator<br />
for <strong>Backing</strong><br />
• Added to resin prior to mixing to speed the cure<br />
of the material when equipment and ambient<br />
temperatures are below 55°F<br />
• Can be used with the following products:<br />
– Loctite ® Nordbak ® <strong>Backing</strong> Material<br />
– Loctite ® Nordbak ® High Impact <strong>Backing</strong> Material<br />
– Loctite ® Nordbak ® High Performance<br />
<strong>Backing</strong> Material<br />
<strong>Loctite®</strong> <strong>Nordbak®</strong> High Performance<br />
<strong>Backing</strong> Material<br />
• For use in water fl ush systems and<br />
protecting wear plates under the most<br />
demanding conditions<br />
• Provides the highest compressive strength<br />
and impact resistance<br />
• High volumetric stability eliminates gaps<br />
between liners<br />
• Nonfl ammable<br />
• High hydrolytic stability provides low<br />
water absorption<br />
Loctite ® Nordbak ® Trowel Mix<br />
• <strong>Backing</strong> material in a trowelable, putty form<br />
• Used to back liners in all types of mills<br />
without dismantling the mill or removing the<br />
grinding charge<br />
• Recommended for backing head liners,<br />
division heads, diaphragms, and securing<br />
liner bolts<br />
• Unused portions may be resealed for<br />
future use<br />
Loctite ® Nordbak ® Locking Compound<br />
• Locks the inner and outer eccentric bushings in<br />
Symons ® Cone <strong>Crusher</strong>s<br />
• High impact system resists temperatures<br />
to 225°F<br />
• Safe and easy to use; saves time and money<br />
• One kit required for all sizes of Symons ® Cone<br />
<strong>Crusher</strong>s up to 5.5 foot<br />
• Two kits required for 5.5-foot Symons ®<br />
Cone <strong>Crusher</strong>s<br />

Product Storage<br />
For better performance, <strong>Loctite®</strong> <strong>Nordbak®</strong><br />
<strong>Backing</strong> <strong>Materials</strong> should be stored at 60°F-75°F<br />
(15ºC- 24ºC), at least 24-48 hours before your pour.<br />
Prolonged exposure to temperatures below 50°F<br />
(10ºC) may affect product performance:<br />
• Diffi culty to mix resin and hardener<br />
• Diffi culty to pour<br />
• Longer cure time<br />

Cure time depends on temperature and mass.<br />
The higher the temperature and the larger the<br />
mass, the faster the cure.<br />
Cold Weather Conditions (100°F)<br />
To increase cure time under extreme warm weather<br />
conditions (100ºF/ 38ºC or higher) you can mix<br />
backing in small masses and/or cool down backing.<br />
