It is also suitable for use over zinc silicate primers.<\/p>\n<h3>Color and gloss level<\/h3>\n<p>Available in aluminum color with a eigluster finish.<\/p>\n<h3>Instructions for use<\/h3>\n<p>Stir the paint well before use until it is homogeneous in color and texture; in practice, up to 5 minutes of stirring is sufficient.<\/p>\n<h3>Drying times and thinning<\/h3>\n<ul>\n<li>Dust dry: 45 minutes at 20\u00b0C.<\/li>\n<li>Paintable: after 24 hours at 10\u00b0C.<\/li>\n<li>Fully cured: at least 3 days at 20\u00b0C before exposure to heat.<\/li>\n<\/ul>\n<p>Normally, dilution is not required. If required, a suitable thinner can be used; refer to the technical data sheet.<\/p>\n<h3>Yield and layer thickness<\/h3>\n<p>The theoretical yield is 18 m\u00b2 per liter at a dry film thickness of 25 \u00b5m. The recommended dry film thickness is 25 \u00b5m per coat.<\/p>\n<h3>Application methods<\/h3>\n<p>Sigmatherm 540 Aluminum can be applied by brush, roller (above the waterline only) or spray equipment. For best results, air spraying is recommended with a nozzle opening of 1.5-2 mm and a pressure of 3-4 bar.<\/p>\n<p><strong>Downloads<\/strong><\/p>\n<ul>\n<li class=\"value\"><a id=\"column_2_uc_product_details_ctl04_lbl_url_sheet1\" class=\"value\" href=\"https:\/\/max.ppg.com\/adaptivemedia\/rendition?id=6366740e7f986e564933498e336109e7c3a6673e\" target=\"_blank\" rel=\"noopener\">Product document<\/a><\/li>\n<li class=\"value\"><a id=\"column_2_uc_product_details_ctl04_lbl_url_sheet2\" class=\"value\" href=\"https:\/\/buyat.ppg.com\/EHSDocumentManagerPublic\/pdf_main.aspx?StreamId=66de3ea25cb4cbc20000&amp;Id=66de3ea45cdcd4030001\" target=\"_blank\" rel=\"noopener\">Safety data sheet<\/a><\/li>\n<\/ul>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>One component heat resistant, moisture curing silicone paint.<\/p>","protected":false},"featured_media":9635,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[135,510,251,975,122],"product_tag":[966],"class_list":["post-20735","product","type-product","status-publish","has-post-thumbnail","product_cat-merken-verf-non-paint","product_cat-primers-verf-non-paint","product_cat-sigma-coatings","product_cat-sigma-primer","product_cat-verf-non-paint","product_tag-online","product_shipping_class-verf","first","instock","taxable","shipping-taxable","purchasable","product-type-variable"],"_links":{"self":[{"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/product\/20735","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/comments?post=20735"}],"version-history":[{"count":0,"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/product\/20735\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/media\/9635"}],"wp:attachment":[{"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/media?parent=20735"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/product_brand?post=20735"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/product_cat?post=20735"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/civharlingen.wjdemo.nl\/en\/wp-json\/wp\/v2\/product_tag?post=20735"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
