Why Different Pigment Systems Cannot Share the Same Binder System

Different watercolor series are not created from a single formulation

Long-term production observations show that different watercolor series are not produced by applying one universal formulation to every pigment.

Although they all belong to the same category of watercolor paints, each series is built upon pigments with different material characteristics.

For this reason, every series develops its own binder system that is designed specifically for its particular material system.

Pigment systems guide the development of the binder system

Long-term formulation development shows that the characteristics of the pigment system determine how the binder system evolves.

Pigments differ in particle structure, density, surface characteristics, and the way they interact with other materials.

For this reason, the binder system is gradually developed to support the behavior of a particular pigment system rather than expecting every pigment to perform well within a single universal formulation.

The development of the formulation therefore follows the material behavior of the pigments instead of adapting pigments to an existing binder system.

Replacing one binder system with another changes material behavior

Long-term production testing showed that replacing the binder system of one series with that of another resulted in noticeable changes in material behavior.

As soon as the relationship between pigments and binder materials changed, the behavior of the entire material system also changed.

These observations demonstrate that material behavior is determined by the interaction of the complete system rather than by any individual ingredient.

For this reason, binder systems cannot simply be exchanged between different watercolor series.

Every material system develops its own characteristics

Long-term production observations show that every material system develops its own combination of material properties.

Depending on the interaction between pigments and the binder system, differences may appear in water reactivation, flow behavior, surface appearance, transparency, flexibility, or other material characteristics.

These observations are not determined by a single material but by the combined behavior of the complete material system.

Mixing different binder systems also changes material behavior

Long-term production observations show that material behavior changes not only when binder systems are exchanged but also when they are mixed together.

Combining components from two different binder systems creates new interactions throughout the material system.

As a result, the balance that had been established for each individual formulation is altered, leading to changes in long-term material behavior.

For this reason, each binder system is developed specifically for its corresponding pigment system rather than being used as a universal formulation.

Formulation development focuses on the entire material system

The objective of long-term formulation development is not to maximize the performance of an individual ingredient.

Instead, the focus is placed on achieving a stable material system in which pigments and binder materials work together as a balanced whole.

Every modification to one component influences the behavior of the remaining materials.

For this reason, formulation development always considers the complete material system rather than optimizing individual ingredients independently.

The Production Archive documents the development of different material systems

The Production Archive documents the long-term development of different binder systems and their interaction with different pigment systems.

These production observations show that each pigment system requires its own binder system and that different material systems cannot simply be exchanged or combined without changing the behavior of the formulation.

These long-term records form an important part of the continuing documentation of watercolor formulation development.
