Knowledge about TINOX TPW series.
1.1 Why the TINOX® TPW Series?
The TINOX® TPW Series delivers an advanced hybrid pigment solution, integrating titanium dioxide (TiO2) with functionalized extenders to achieve exceptional optical and functional performance. Designed for the coatings industry, it combines efficiency, cost-effectiveness, and superior quality, setting a new standard in pigment technology.
1.2 Optimized Light Scattering through Hybrid Technology
The TPW series features a precisely engineered blend of ultrafine, surface-treated extenders and high-quality TiO2 pigments, unlike conventional TiO2–filler combinations. This hybrid structure ensures uniform particle distribution and optimal spacing after drying, significantly enhancing scattering efficiency and opacity—an advantage unattainable with simple TiO2–filler mixtures.
1.3 Advantages & Applications
The TINOX® TPW series combines state-of-the-art hybrid pigment technology with optimized particle distribution for maximum light scattering and opacity. Through targeted post-treatment processes, the particle surfaces are functionalized, ensuring excellent compatibility with common binders, improved dispersibility, high homogeneity, and enhanced efficiency in coatings. The following section provides a detailed explanation of the advantages of the TINOX® TPW Series.
2.1 Optimal particle distribution for improved surface quality
The TINOX® TPW technology not only enables more efficient use of the TiO₂ pigment but also ensures a more homogeneous surface structure. Unlike conventional formulations with separate fillers, it prevents excessively coarse or uneven particle distributions, thereby avoiding deficiencies in opacity and gloss performance. This results in an optimal balance of brilliant whiteness, high opacity, and the application of our products in semi-gloss or gloss finishes.
2.2 Excellent dispersibility for maximum efficiency
The TINOX® TPW series excels in dispersibility across both aqueous and solvent-based systems. Through a finely controlled post-treatment process, the hybrid pigments are precisely functionalized, ensuring rapid and uniform dispersion. This maximizes pigment efficiency, reduces processing time, and enhances formulation stability. TPW delivers exceptional homogeneity across various binder systems, resulting in high-quality coatings with superior optical properties.
2.3 Optimized technology for semi-gloss and gloss applications
Engineered for high-performance semi-gloss and gloss applications, the TINOX® TPW series addresses the limitations of conventional extenders. Unlike traditional fillers that compromise specular reflection due to surface irregularities, TPW’s ultrafine, functionalized particles ensure optimal film smoothness. Its surface chemistry is compatible with diverse binders, facilitating ideal pigment alignment during drying, thereby achieving gloss levels beyond the reach of standard TiO₂–extenders or blends.
2.4 Added value through efficiency and cost-effectiveness
The TINOX® TPW series combines technical innovation with economic optimization. Its tailored surface functionalization reduces titanium dioxide usage, stabilizing costs and improving resource efficiency. This offers a competitive edge over conventional formulations reliant on separate extenders, delivering strong performance with cost savings.

3. Test Result – Performance Overview
Based on comprehensive testing, the optical and functional performance of TPW products is evaluated across diverse formulations, with a focus on key metrics such as brightness, undertone, opacity, and gloss. These analyses quantify the superior value of TPW technology over traditional TiO₂-based systems.
3.1 Vinyl Acetate–Ethylene Copolymer (VAE) Interior Dispersion Paint
VAE-based interior dispersion paint (Pigment Content = 10%). As shown in Fig. 2, TPW-716 demonstrates brightness (L-value) and opacity comparable to TiO₂, with a lower undertone (b-value), achieving performance on par with TiO₂ in this formulation.
3.2 Styrene-Acrylic Lacquer – Water-Based
Styrene-Acrylic with 20% Emulsion (PVC = 65%). TPW-714 and TPW-716 were evaluated against TiO₂-pigments R-2140 and R-2160. TPW-716 exhibits a whiteness index nearly matching R-2160 and surpassing R-2140, with a yellowness index slightly higher than R-2160. TPW-714 delivers opacity comparable to TiO₂-pigments, offering a cost-efficient alternative despite its slightly lower brightness.
3.3 Acrylic Enamel Paint – Water-Based
Acrylic enamel with 75% emulsion (PVC = 25%). The graph shows the whiteness index, yellowness index, and gloss of the TPW pigments TPW-714 and TPW-716 compared to the TiO₂-pigments R-2140 and R-2160. TPW-716 achieves a whiteness index very close to that of R-2160 and higher than that of R-2140. The yellowness index of TPW-716 is only slightly higher than that of R-2160. The opacity levels of TPW-714 and TPW-716 are similar and, in this application, come closest to that of R-2160.
3.4 Solvent-Based Acrylic Paint
ALFACRYL 26 x B65: 20% & Pigment: 66%. Figure 8 compares TPW-714 and TPW-716 with TiO₂-pigments R-2140 and R-2160 in brightness, undertone (b-value), opacity, and gloss. Both TPW pigments achieve near-TiO₂ brightness, with TPW-716 showing a slightly higher undertone and TPW-714 matching TiO₂ opacity. Despite marginally lower brightness and higher undertone, TPW-714 is a cost-effective alternative. TPW-714 suits semi-gloss applications, while TPW-716, with higher gloss, is viable for high-gloss coatings.
