Comparison of Premium primer vs local primer
| Parameter | Local Interior Primer | Premium Rhoplex AC-34 Primer |
|---|---|---|
| Binder Content (% w/w) | 3.8% (≈1.9% solids, acrylic) | 47.4% (acrylic emulsion) |
| Pigment/Extender Load (% w/w) | ~53% (mainly Talc, CaCO₃, Wollastonite, trace TiO₂) | ~33% (TiO₂ rutile + anatase + mica + CaCO₃) |
| TiO₂ Content | 0.76% rutile (very low hiding) | 19.48% rutile + 2.16% anatase (high opacity) |
| Pigment–Binder Ratio (Weight, solids) | ~28 : 1 | ~0.7 : 1 |
| Pigment–Binder Ratio (Volume, solids) | ~10.6 : 1 | ~0.9 : 1 |
| PVC (Pigment Volume Concentration) | ~91% | ~40–45% |
| CPVC (Critical PVC) | ~64% | ~60–65% |
| Position vs CPVC | Well above CPVC (very porous, chalky, absorbent) | Below CPVC (dense, durable film) |
| Film Properties | High porosity, matte, sandable, good holdout, poor scrub resistance | Strong adhesion, scrub-resistant, alkali-resistant, more like a washable sealer |
| Coverage (practical) | 8–10 m²/L @ 25–30 µm DFT | 14–16 m²/L @ 25–30 µm DFT |
| Additive System | Simple (HEC thickener, Alphox wetting agent, SHMP dispersant, MEG, ammonia) | Advanced (Tamol dispersant, Triton surfactant, structured rheology via Keltex, dual defoamers, glycol coalescent, mildew biocide) |
| Target Segment | Low-cost interior primer for sealing plaster/masonry | Premium interior/exterior primer with high hiding and durability |
