Titanium dioxide replacement For Paint
3M™ Glass Bubbles in acrylic paint – cost-effective titanium dioxide replacement that maintains scrub properties without decreasing opacity
3M™ Glass Bubbles
This case study by 3M Advanced Materials Division aims to reduce formulation cost of acrylic paints by replacing titanium dioxide with equal volumes of 3M™ Glass Bubbles iM16K. The proposed formulations are to maintain scrub properties without decreasing paint opacity.
Baseline Formulations
The following formulations for water-based flat acrylic architectural paints at 45 PVC were compared in this case study:
Formula A
No glass bubbles
Formula B
Replaced 5% wt. TiO2 with 3M™ Glass Bubbles iM16K
Formula C
Replaced 15% wt. TiO2 with 3M™ Glass Bubbles iM16K
Formula D
Replaced 15% wt. TiO2 with other fillers

Summary
Replacing titanium dioxide with glass bubbles reduces paint density with a statistically significant improvement in opacity and scrub resistance.
Scrub resistance
Scrub resistance is maintained
Opacity
Drop in opacity controlled
Density
Weight per gallon of paint decreased when
replacing TiO2 with 3M™ Glass Bubbles
Conclusion
3M™ Glass Bubbles can offer the formulator alternatives to optimizing cost while maintaining or improving opacity and durability properties such as scrub resistance. Further formulation optimizations should be tested to enhance desired properties.
