A Water-based Strippable Coating

A new water-based strippable protecting coating was prepared with polyurethane emulsion and nano-CaCO3. The influence of nano-CaCO3 on the coating was studied. When the dosage of nano-CaCO3 was 2%, the coating had the best strippable performance. The average tensile strength and average elongation at the break point of the coating was 5.74 MPa and 259.03% respectively, indicating that this protective coating has good strippable performance.
