Formulating Coatings with the Latest Generation of Water-Borne Urethanes- Superior Durability Combined with Environmental Responsibility

Coatings formulators and manufacturers of protective and decorative coatings are often forced to make compromises. Ideally any protective coating will be a balance of a number of critical properties including:

  • Processing characteristics such as speed, wetting, and consistency
  • Curing and drying conditions required
  • Appearance and durability of the finished coating
  • Risks and hazards to exposed workers
  • Risks and hazards to the environment
  • Cost

Recent improvements in our understanding of water-borne polyurethane dispersions are leading to a change in thinking regarding what is possible for a number of long-established industries such as:

  • Thin film concrete sealers and top coats
  • Wood flooring Top Coats
  • Furniture coatings

Through a combination of long experience, manufacturing expertise, and unique newer raw material approaches a new generation of polyurethane dispersions have been emerging. It is being established that the chasm between durability and environmental responsibility can be bridged with the use of carefully designed polyurethane dispersion technology.

Characteristics of the New Materials

The following are some of the key characteristics of our waterbase polyurethane dispersions designed for use by coating formulators:

  • Aliphatic for superior clarity and UV resistance
  • Improves Abrasion, Chemical Resistance, Adhesion, Durability, and Aesthetics
  • Extremely low VOC with no Cosolvents
    • No NMP, TEA, and APEO Free
    • “Clean” SDS for worker safety

One of the most recent examples of this technology has been the introduction of Chase SF2600 a water-borne co-polymer. This specific product was designed by our polymer scientists as a cosolvent free, highly durable, hot tire stain resistant, co-polymer for the formulation of wood and concrete penetrating sealers and top coatings. Properties of this product include: Starting formulas are available.
