A 10:1 system can also perform well but normally requires accurate metering of the smaller component.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always confirm whether the ratio is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>By weight<\/li>\n\n\n\n<li>By volume<\/li>\n\n\n\n<li>Suitable for manual weighing<\/li>\n\n\n\n<li>Compatible with existing dispensing equipment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A 1:1 ratio by weight is not automatically 1:1 by volume because the two components may have different densities.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mixed Viscosity<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For mold-making decisions, mixed viscosity is usually more useful than the separate viscosity of Part A or Part B.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/topsilsilicone.com\/pt\/silicone-viscosity-too-high-or-too-low-how-to-choose\/\" data-type=\"post\" data-id=\"8669\">Lower viscosity<\/a> can help the material:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enter fine details<\/li>\n\n\n\n<li>Fill narrow spaces<\/li>\n\n\n\n<li>Level more easily<\/li>\n\n\n\n<li>Move trapped air toward the surface<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">However, lower viscosity does not automatically mean better mechanical properties or longer mold life. It also does not replace correct mixing, vacuum degassing or proper mold design.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Viscosity should ideally be compared using similar temperatures and measurement conditions. Some filled or thixotropic materials may also show shear-dependent behavior, making a single cP value an incomplete description of pouring behavior.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tempo de trabalho<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Working time or pot life represents the available processing window after Parts A and B are mixed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exact definition may vary between suppliers. It may refer to the time before viscosity rises significantly, the time before gel begins or the recommended pouring period.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Actual working time can be affected by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Workshop temperature<\/li>\n\n\n\n<li>Batch size<\/li>\n\n\n\n<li>Mixing speed<\/li>\n\n\n\n<li>Vacuum degassing time<\/li>\n\n\n\n<li>Tamanho do molde<\/li>\n\n\n\n<li>Heat exposure<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A 10-minute working time may suit a small open mold but create a high risk for a large PU prototype mold requiring mixing, vacuum degassing and controlled pouring.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Expert rule:<\/strong> A fast silicone is productive only if it remains workable long enough to complete the process correctly.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">Demold Time<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Demold time is not always the same as full cure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A silicone may be firm enough to remove from the master while its tear strength, hardness or dimensional stability continues to develop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Buyers should distinguish between:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Tack-free time<\/li>\n\n\n\n<li>Demold time<\/li>\n\n\n\n<li>Functional cure<\/li>\n\n\n\n<li>Full cure<\/li>\n\n\n\n<li>Post-cure, where applicable<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For demanding production, ask when the mold can safely receive its first casting\u2014not only when it can be removed from the master.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: Evaluate the Mechanical Balance<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hardness, tear strength, tensile strength and elongation must be read together.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dureza Shore A<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/topsilsilicone.com\/pt\/dureza-shore-a-para-fabricacao-de-moldes-de-silicone\/\" data-type=\"post\" data-id=\"5898\">Dureza Shore A<\/a> measures resistance to indentation.
