ShieldPrime SP was designed and developed specifically for adhering Polyurea to rubber conveyor belts. It is epoxy based, two-part, 100% solids, but uses additional ingredients that are only made in one plant in the world. So when we say it is unique, we aren’t kidding!

Key benefits to the ShieldPrime SP:

• 100% solids
  
• 1:1 ratio
  
• Spray or hand applied
  
• Can apply the polyurea over wet primer (“wet-on-wet”) – huge benefit for timing
  
• Works with the flexibility of the belt
  
• Bonds so well that the weak point is the rubber

The primer can be applied by hand on stationary conveyors, but it is most efficiently applied to running conveyor belts with high pressure plural component spray equipment, which we can supply and configure for you.

We have tried more than 10 different primers over the years perfecting this system, from a range of different suppliers, but none of them met all the criteria. Just finding something that can stick to rubber consistently with minimal preparation is one thing, but then to be able to stick to the polyurea too, that is special.

The ShieldPrime SP was designed for conveyor belts, but it also has applications as an intercoat primer for elastomeric polyurea and polyurethane, as well as for other difficult substrates like HDPE, PVC, etc.

Other rubber lining systems can also be repaired or replaced with polyurea, without needing to fully remove them if the ShieldPrime SP primer is used. This provides considerable savings for things like rubber lined tanks, agitators, floatation cells, chutes, etc.
