Preparation of a New Water-Based Strippable Protected Coating
A new water-based strippable protected coating was made by polyurethane emulsion and nano-CaCO3 was put in the coating as the fillers. The influence of nano-CaCO3 on the coating was discussed and the influence of film thickness on the coating was studied. The performance of the coating was tested, and when the dosage of nano-CaCO3 was 2% and the film thickness was 0.13~0.14mm, the film had the best strippable ability. Its average mechanics intensity was 5.72MPa and average elongation at break was 258.35%.
