Promat® SBR Bonding Latex

Advantages

  • Strongly adhering mechanical keycoat
  • Easy to apply

Promat® SBR Bonding Latex is a single pack, synthetic latex for use as a keycoat for fire protective coatings. It is spray applied after first mixing with PROMASPRAY®-F5.

Promat® SBR Bonding Latex forms part of the PROMASPRAY®-C450 and PROMASPRAY®-F5 passive fire protection system and is designed for application to primed steel or concrete substrates.

After mixing with PROMASPRAY®-F5, Promat® SBR Bonding Latex forms a tough, textured, strongly adhering mechanical keycoat. Once the mixture hasccured, neat PROMASPRAY®-C450 or PROMASPRAY®-F5 can be applied over it.

Applications

Keycoat for fire protective coating. To be used with PROMASPRAY® fireproofing product.

Substrates Preparation

The substrate shall be clean, dry and free from visible moisture (including condensation), dust, loose millscale, loose rust, oil and any other condition preventin good adhesion.
Typical Substrates Preparation

Please contact Promat Technical Department to confirm compatibility of the primer with Promat® SBR Bonding Latex.
Application Limitations

Promat® SBR Bonding Latex may be applied when the substrate and air temperatures are at least 2°C and rising. Maximum substrate and air temperature is 45°C.

Substrate temperature should be at least 2°C above dew point temperature. Application should not take place if the temperature is 4°C and falling.
Application Method

Add 1 volume of water to 1 volume of Promat® SBR Bonding Latex. Add 20kg of PROMASPRAY®-F5 to 17kg of diluted Promat® SBR Bonding Latex and mix for 3 minutes.

Apply with a rotor/stator type spray machine, or for small areas a gravity fed hopper gun, to give 20-50% coverage of substrate.
Application Setting Time

Over coating interval: When touch dry depending on temperature
