Crusher Backing Materials 

Loctite ® Nordbak ® Backing Material 

• 100% solids epoxy compound for backing wear 

plates in cone crushers and grinding mills 

• Provides high compressive strength and 

impact resistance 

• High volumetric stability eliminates gaps 

between liners 

• Nonfl ammable 

• Pourable compound requires no melting or 

special equipment 

Loctite ® Nordbak ® High Impact 

Backing Material 

• Excellent resilience while retaining high 

compression and tensile strengths 

• Maintains all other features of regular Loctite ® 

Nordbak ® Backing Material (heat distortion 

temperature, ease of mixing and pouring) 

Loctite ® Nordbak ® Accelerator 

for Backing 

• Added to resin prior to mixing to speed the cure 

of the material when equipment and ambient 

temperatures are below 55°F 

• Can be used with the following products: 

– Loctite ® Nordbak ® Backing Material 

– Loctite ® Nordbak ® High Impact Backing Material 

– Loctite ® Nordbak ® High Performance 


Loctite® Nordbak® High Performance

protecting wear plates under the most 

demanding conditions 

• Provides the highest compressive strength 

and impact resistance 

• High volumetric stability eliminates gaps 

between liners 

• Nonfl ammable 

• High hydrolytic stability provides low 

water absorption 

Loctite ® Nordbak ® Trowel Mix 

• Backing material in a trowelable, putty form 

• Used to back liners in all types of mills 

without dismantling the mill or removing the 

grinding charge 

• Recommended for backing head liners, 

division heads, diaphragms, and securing 

liner bolts 

• Unused portions may be resealed for 

future use 

Loctite ® Nordbak ® Locking Compound 

• Locks the inner and outer eccentric bushings in 

Symons ® Cone Crushers 

• High impact system resists temperatures 

to 225°F 

• Safe and easy to use; saves time and money

Product Storage 

For better performance, Loctite® Nordbak® 

Backing Materials should be stored at 60°F-75°F 

(15ºC- 24ºC), at least 24-48 hours before your pour. 

Prolonged exposure to temperatures below 50°F 

(10ºC) may affect product performance: 

• Diffi culty to mix resin and hardener 

• Diffi culty to pour 

• Longer cure time

Cure time depends on temperature and mass. 

The higher the temperature and the larger the 

mass, the faster the cure. 

Cold Weather Conditions (100°F) 

To increase cure time under extreme warm weather 

conditions (100ºF/ 38ºC or higher) you can mix 

backing in small masses and/or cool down backing.
