The spray gun is used to apply the foam and coatings onto the wall or other substrate. The spray gun is important, because this is where the isocyanate and resin materials meet and react.
Proper mixing is critical to ensure that the material properties are established and maintained over the life of the building. When choosing a spray gun, it is important to choose a spray gun that is easy to maintain, easy to spray and applies material according to manufacturer’s recommendations.
What is the difference in spray guns?
Graco Fusion spray guns are available with air purge, mechanical purge, and liquid purge. Each gun has its own unique benefits:
With long-life mix chamber and durable side seals, Fusion air purge guns are designed to reduce maintenance and downtime, and provide a better mix.
The most commonly used guns in the spray foam and coatings market
Uses a blast of compressed air to keep the mixing chamber clean
Contains fewer parts than mechanical purge guns
Easier to spray and maintain than mechanical purge guns
ClearShot Technology sets the Fusion CS gun apart from every other applicator. With its revolutionary technology, the Fusion CS is poised to virtually eliminate drilling of the mix chamber – increasing your spraying uptime and reducing downtime spent on maintenance.
Most recently introduced to the spray foam market
Liquid is dispensed into the mix chamber at each trigger pull, removing build-up material and keeping the mix chamber clean
Uses significantly less purge air than an air purge gun
Switch from large to small spray patterns in seconds
Whether you’re spraying polyurea coatings or spray foam insulation, the Fusion MP Gun handles it all. Its rugged design provides excellent mix and material properties – giving you great results at the jobsite.
Use a steel rod to physically push any residual material out of the mix chamber to keep it clean
Contain more parts than air purge guns
Require more maintenance than air purge guns
Offers widest range of flow rates
NOTE: The mixing chamber is the area where the isocyanate and resin materials meet and mix. The mixing chamber needs to stay as clean as possible to maintain good material properties and a consistent spray pattern.
