PPG Mixing Machines

There are a number of official methods approved for mixing PRC or Pro-Seal sealants packaged in Semkits including:

• Mixing by hand (Hand Mixing of Semkits)
• Mixing with a Semco Model 1088
• Mixing with a Semco Model 285-A (referred to as Portable Electric Semkit Package Mixer)

• Mixing with a Semco 388 Mixer (referred to as an Automatic Semkit Package Mixer)

All other mixing methods are not authorized by the formulator and may result in issues with the material's application and performance properties.  

Hand Mixing of Semkits

Mixing by hand is an approved method for mixing PRC and Pro-Seal sealants packaged in Semkits. For detailed written instructions, please contact our technical service team or watch the brief videos below on how to mix an injection-style Semkit or a barrier-style Semkit by hand.

Semco Model 1088 Semkit Package Mixer 

The Semco Model 1088 Semkit Package mixer provides complete automatic mixing of filled Semkit Packages. Use of the mixer will minimize operator set up of the machine for different kit configurations, reduce worker fatigue, and assures the user a more thorough and consistent mix, kit to kit.

Semco Model 285-A Semkit Package Mixer 

The Semco Model 285-A Semkit package mixer provides semi-automatic mixing of filled Semkit packages. Use of the mixer reduces worker fatigue and assures a more consistent, uniform mix. The drive spindle rotates the mixing rod while the operator strokes the cartridge vertically. This permits the rotating dasher to thoroughly mix the materials. The bell timer alerts the operator when the mix cycle is completed.

Semco Model 388 Semkit Package Mixer

The Semco Model 388 Semkit package mixer provides automatic mixing of filled Semkit packages. Use of the mixer reduces worker fatigue and assures the user a more thorough and consistent mix, kit to kit. This model is available in various forms, depending on the Semkit packaging size.

*This mixing method is being phased out, and PPG recommend the use of the Semco Model 1088 Semkit Package Mixer in its’ place.
