Sunstar’s Next Generation Low Density Sealers
Offer weight savings with superior processability, gap coverage, and Class A paintable appearances for automotive
paint-shop applications.
Formulated with the 3M™ Glass Bubbles made with current technology, these one component PVC body sealers are designed to retain
density and minimize equipment wear under robust processing conditions while also providing high strength, elongation, and adhesion to
Electrodeposition coatings on all automotive substrates.
Next Generation of Lightweighting

™
Glass Bubbles
3M Glass Bubbles are hollow glass microspheres that are an
industry-proven solution that can replace heavier fillers to help
reduce the overall weight of automotive sealants.

Recommended Equipment Configuration
Graco Switch 3D Gun with Slot Tips
Pros:
•
Consistent slot stream thickness from edge to edge
•
Performed the best in gap coverage tests
•
Ability to dispense from 3 different tip configurations gives
flexibility in programming robot paths to optimize cycle time
•
Tip seal shut off for clean start and stops
Cons:
•
Have to be close to the substrate (7 – 10 mm) for best quality
Graco Precision Swirl with iQ Snuff Back Valve
Pros:
•
Can be programmed to dispense at a distance from the substrate,
allowing for better clearance from objects on car body
•
Simple robot programming for most motion paths
Cons:
•
Harder to program robot paths with tighter clearance restraints
since an offset is required for pattern width
