Lighter Bonds, Better Rheology, Fewer Callbacks
Density down, sag control up, shrinkage gone.
Spherical low-oil-absorption fillers that thicken without thixotrope overload — for construction sealants, aerospace adhesives, automotive seam sealers and marine caulks.
Application scenarios
01
Construction & glazing sealants
Lower density → more linear meters per cartridge; controlled slump.
02
Structural & aerospace adhesives
Bondline weight reduction with maintained lap-shear performance.
03
Automotive seam sealers
Lower mass per vehicle, paintable surfaces, anti-sag on verticals.
04
Marine & below-waterline caulks
Closed-cell filler — no wicking, no osmosis pathways.
Why switch — on both ledgers
Economic advantages
- Sell by the cartridge, fill by volume: density 0.32 g/cc filler extends each batch
- Replace fumed silica partially — cut cost and dust exposure
- Lighter sealant = cheaper freight on a heavy product
Functional advantages
- Ball-bearing rheology: viscosity control without shear-thin overload
- Low shrinkage on cure
- Improved insulation inside the joint
- Chemical inertness across PU, silicone, epoxy, MS-polymer
