- 20% to 45% PVC Water-based Coatings
1) Replace 10% of the TiO₂ with the same weight of FP‐460
2) Remove 10% of the largest particle size extender/filler in the formulation
This will result in a slight reduction in the PVC of the paint which helps to maintain the gloss level of the reformulated paint. At this stage the opacity of the formulation should be checked and if necessary a small level of opaque polymer (typically between 0.5% and 1.0% on total formulation weight) should be added. If opaque polymer cannot be used, then one or two percentage points of TiO₂ should be added back to the formulation.
If the replacement is successful following the 10% protocol, then further reductions can be attempted and we recommend doing this in 2.5% increments.
E.g.
1) Replace 12.5% of the TiO₂ with the same weight of FP‐460
2) Remove 10% of the largest particle size extender/filler in the formulation
3) Adjust opacity using small additions of opaque polymer or replacing some TiO₂

Technical Details & Test Data
- 50% to 90% PVC Water-based Coatings
1: Test using a replacement ladder of 5, 10, 15 and 20% FP-460.
2: Make a 1:1 weight for weight replacement of TiO₂ with Opacity Pigment.
3: For the optimum performance, the order of addition, where possible, should be:
i) Normal Millbase liquid ingredients and HEC thickener if present.
ii) Opacity Pigment™ followed immediately by
iii) TiO₂ Pigment
iv) then extenders
4: Mill as normal - no additional milling time is necessary.
5: Complete paint as normal.- Typical Pigment
