Our Dispurez® polyurethane dispersions are non-hazardous and ideal for all types of rigid plastic and flexible film applications.
Whether used as PU dispersions or combined with acrylic, they produce hard, crystalline polyurethane coatings with comparable properties to equivalent coatings based on pyrrolidone solvents.
Our service is extremely flexible and Dispurez® PU dispersions can be tailored to provide outstanding performance in very specific applications. By adapting our chemistry to suit you, we can provide polymers for all kinds of plastic substrates from rigid uPVC to flexible PET.

Dispurez 103
- Tough and flexible waterborne polyurethane dispersion with excellent hydrolysis and chemical resistance
- Excellent adhesion to wide variety of plastics (ABS, Polycarbonate, PET, etc.)
- Excellent weathering resistance, when used in combination with suitable UV stabilisers
- Durable coating for interior and exterior automotive plastic substrates
- Can be added to WB waterproofing acrylic formulation to improve toughness (tensile strength) and reduce water uptake
- For improved UV resistance, we recommend Tinuvin 292 in combination with Tinuvin 9945 DW (0.5% each)
