Microspheres create tiny air-filled voids within the paint, improving its thermal insulation property.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Good Filling Capacity<\/h3>\n\n\n\n<p>The addition of microspheres increases the solid content per unit volume of the paint, resulting higher filling capacity of the paint and providing better coverage for cracks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Weight Reduction<\/h3>\n\n\n\n<p>Due to the extremely low density of microspheres, the weight of the paints can be significantly reduced. By adding 5-10 percent by weight of wet expanded microspheres, a can of 20 kg of paint will reduce its weight to 10-15 kg.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cost Reduction<\/h3>\n\n\n\n<p>The weight reduction of paints saves workload, energy and transportation costs. Moreover, the low demand of microspheres for binders means saving the binder cost.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Higher Water Vapor Permeability<\/h3>\n\n\n\n<p>Paints with microspheres have higher permeability compared to the ordinary paints, which may extend the shell life of the paint.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lower Water Absorption<\/h3>\n\n\n\n<p>Paints with microspheres have lower water absorption compared to the ordinary paints.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Matting Surface<\/h3>\n\n\n\n<p>Adding a small amount of microspheres to the paint can achieve different matting surface with different particle size of microspheres.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reflectivity Properties of Cool Roof Coating with Microspheres<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"732\" src=\"https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3-1024x732.png\" alt=\"cool roof coating insulation paint3\" class=\"wp-image-2242\" srcset=\"https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3-1024x732.png 1024w, https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3-300x214.png 300w, https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3-768x549.png 768w, https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3-1536x1098.png 1536w, https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3-18x12.png 18w, https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3-1600x1144.png 1600w, https:\/\/expandablemicrosphere.com\/wp-content\/uploads\/2024\/07\/cool-roof-coating-insulation-paint3.png 1634w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">cool roof coating insulation paint3<\/figcaption><\/figure>\n\n\n\n<p>The main effect of expanded microspheres is probably reflection rather than insulation.
