This method can be used for a wide range of products, from sheets having only slight water repellence to sheets with wax sizings or coatings that have a high degree of water repellence. <\/p>\n<p> This method is useful for sheets treated with such materials as a stearic chrome complex, polyvinylidine chloride, polyvinyl compounds, commercial varnishes, paraffin wax impregnations, and paraffin wax coatings. The sheet may be produced directly on the paper machine or subsequently coated. <\/p>\n<p> The method is not practical for plastic extrusion coatings, heavily wax-coated, not certain curtain-coated grades which have a hard wax\/resin type of coating, for which the test period becomes prohibitively lengthy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Water Repellence of Paper and Boards<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/tappi\/\"><b>TAPPI<\/b><\/a><\/td>\n<td>2015-03-16<\/td>\n<td>3<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":0,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[1203,2661],"product_tag":[],"class_list":{"0":"post-689995","1":"product","2":"type-product","3":"status-publish","5":"product_cat-85-080-01","6":"product_cat-tappi","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/689995","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=689995"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=689995"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=689995"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
