- Eco-Friendly Composition: This advanced alkyd emulsion is cosolvent-free, and explicitly does not contain APEO (alkylphenol ethoxylates), VOC (volatile organic compounds), or SVOC (semivolatile organic compounds), making it an environmentally responsible choice for modern paint formulations.
- Versatile Application and Performance: Ideal for house and trim paints, NECOWEL 5100 offers fast drying properties, excellent weather and yellowing resistance, and high gloss, facilitating a seamless transition from solvent-based to high-quality water-based systems.
NECOWEL 5100, developed by ASK Chemicals, stands out as a rheologically modified alkyd emulsion designed to bridge the performance gap between traditional solvent-based paints and modern water-based alternatives. Its unique formulation addresses common challenges associated with aqueous systems, such as poor brushability and inadequate leveling, by imparting more "Newtonian" flow behavior. This allows for the creation of high-quality house and trim paints that are not only environmentally friendly but also deliver superior application properties and durability.
Understanding NECOWEL 5100: A Technical Deep Dive
The Core of Advanced Aqueous Paint Systems
NECOWEL 5100 is a medium oil length alkyd emulsion, neutralized with ammonia. A key characteristic that sets it apart is its internal rheological modification. This modification is crucial because it significantly improves the flow characteristics of aqueous house paints, making them comparable to solvent-based systems that traditionally offer excellent leveling properties. Unlike many aqueous trim paints that exhibit strong pseudoplastic, shear-thinning properties leading to rapid viscosity increases after brushing and resulting in brushmarking and insufficient leveling, paints formulated with NECOWEL 5100 demonstrate a more consistent, "Newtonian" viscosity profile.
Compositional Advantages and Environmental Profile
A significant advantage of NECOWEL 5100 is its commitment to environmental responsibility. It is entirely cosolvent-free, eliminating the need for additional solvents that contribute to VOC emissions. Furthermore, it is explicitly free of APEO, VOC, and SVOC, addressing growing concerns about harmful chemicals in paint products. This makes NECOWEL 5100 an attractive option for manufacturers seeking to formulate eco-conscious paints without compromising on performance.

Performance Characteristics in Paint Formulations
Beyond the Basics: Achieving Superior Paint Attributes
The rheological modification of NECOWEL 5100 directly translates into several performance benefits for the final paint product:
Improved Brushability and Leveling
One of the primary challenges with water-based alkyd systems has been maintaining good brushability and leveling. NECOWEL 5100 overcomes this by providing fluidity properties similar to solvent-based alkyd systems. This means that during application, the paint maintains a consistent viscosity, allowing for smooth spreading and excellent leveling, which reduces brush marks and ensures a professional finish. In most cases, the internal rheological modification of NECOWEL 5100 negates the need for additional associative thickeners, simplifying formulations and potentially reducing costs.
Drying Properties and Durability
NECOWEL 5100 offers fast drying properties, which is highly desirable for house and trim paints, enabling quicker recoat times and faster project completion. Beyond drying, paints formulated with NECOWEL 5100 exhibit good weathering and yellowing resistance, ensuring long-term aesthetic appeal and protection. This makes it an ideal choice for exterior applications and surfaces exposed to environmental stressors.
High Gloss and Aesthetic Appeal
This alkyd emulsion is designed to achieve a high gloss finish, a crucial attribute for many decorative and protective coatings. The high gloss not only enhances the aesthetic appeal but also contributes to the perceived quality and cleanliness of the painted surface.
