“…33,34 Guadagno et al 35 reported a healing efficiency of 97.75% for a sample containing 10 wt% microcapsules by using a fracture toughness test. Es-haghi et al 36 used a water vapor transmission test (WVT) to calculate healing efficiency. Pingkarawat et al 37 used tension and compression tests for calculating healing efficiency in mendable composites containing self-healing thermoplastic agents.…”

“…There was no significant difference between adding microcapsules in primer and adding in topcoat. The number of primer and topcoat had a slight effect on the hardness, which was mainly due to the uneven distribution of microcapsule particles in the coating process [31]. The adhesion of No.…”

The purpose of this paper is to explore the effect of urea-formaldehyde (UF) with waterborne emulsion microcapsules on the optical, mechanical and aging resistance properties of waterborne coatings from the perspective of coating process. In this paper, the microcapsules were prepared with UF resin as the wall materials and waterborne emulsion as the core materials. Based on the coating process, the optical, mechanical and aging resistance properties of the waterborne acrylic coatings with microcapsules for American lime were tested. The good coating process is three layers of primer, two layers of topcoat, and adding microcapsules into primer. The results showed that the coating process had little effect on the color difference of the paint film with microcapsules, the gloss of the paint film prepared by the good coating process was basically not changed, and the mechanical properties of the paint film were good. At this time, the hardness grade of the paint film was 3H, the adhesion was grade 0, the impact resistance was 110.0 N·cm−2, and the elongation at break was 29.7%. The microcapsules added to the primer had better liquid resistance than those added to the topcoat. The paint film had good stability and aging resistance, and could inhibit the generation of microcracks to a certain extent. The paint film prepared by the good coating process had better comprehensive performance. This work provides a technical reference for self-healing of the waterborne coatings on American lime.

“…Ataei et al found that the gloss and bond strength of the coatings decreased and the flexural elongation decreased with the increase of the concentration of microcapsules in epoxy coating containing microencapsulated alkyd resin based on coconut oil [17]. These reports focused on improving the water resistance, corrosion resistance and mechanical properties of waterborne coatings, but there are few reports on the toughness enhancement of waterborne coatings [18][19][20][21][22].…”

The modification experiment of waterborne coating was carried out by adding microcapsules. The wall material of the microcapsule was urea-formaldehyde resin and the core material of the microcapsule was epoxy resin. Core material can improve the toughness of the coating and prevent the cracking of the coating. The influences of different contents of microcapsules and the order of adding microcapsules in the coating process on the properties of gloss, color difference and toughness were studied. The results showed that the gloss of the waterborne coating decreased with the increase of microcapsule content. The color difference of coating increased first and then decreased, and when the microcapsule content was 8.0%, the color difference was the largest. The toughness of the coatings also increased first and then decreased. When the content of the microcapsule was 10.0%, the toughness of the coating was significantly enhanced. When the microcapsules with a content of 10.0% were added to the waterborne coating, under the same process, the coating gloss of microcapsules added to the primer was relatively high, and the coating gloss was the highest when the coating process was three-layer primer and two-layer topcoat. The microcapsule had little effect on the color difference of coating in different coating processes. When the coating process was three-layer primer and three-layer topcoat, the coating toughness was the best when microcapsules were added to the topcoats. This study provides a basis for industrial application of waterborne coatings to enhance their toughness.
