The mixing ratio is 1:1 by weight. The silicone flows well, cures without shrinking, and has a high tear strength of 20 N\/mm, ensuring molds last for many castings.\u003c\/p\u003e\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eHigh tear strength (20 N\/mm):\u003c\/strong\u003e resistant to repeated demolding of undercuts.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eShrink-free curing:\u003c\/strong\u003e dimensionally stable molds, can be accelerated with heat.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eExcellent flow:\u003c\/strong\u003e fills fine details and sharp corners.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eElongation at break 480%:\u003c\/strong\u003e wide margin during demolding.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003e1:1 mixing ratio:\u003c\/strong\u003e easy to weigh, no calculations required.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBlue:\u003c\/strong\u003e high contrast with light-colored casting materials such as plaster and concrete.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eMold making and core molds where dimensional stability and precision are paramount.\u003c\/li\u003e\n\n\u003cli\u003eConcrete casting and artificial stone, thanks to good compatibility with concrete formulas.\u003c\/li\u003e\n\n\u003cli\u003eSanitary ware and building elements.\u003c\/li\u003e\n\n\u003cli\u003eMolds for plaster, coatings, polyurethane resins, and acrylic resins.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eProcessing\u003c\/h3\u003e\n\u003col\u003e\n\n\u003cli\u003eShake the base and catalyst separately to eliminate any sedimentation.\u003c\/li\u003e\n\n\u003cli\u003eWeigh both components 1:1; use a separate spoon for each component.

Curing can be inhibited by sulfur, nitrogen, and tin compounds, latex gloves, some plastelines, condensation silicones, and certain 3D printing materials. The TDS also warns that some petroleum jellies may hinder curing. When in doubt, perform a small test first. Ensure the surface is clean, free of grease, and dry.\u003c\/p\u003e","brand":"Zhermack","offers":[{"title":"Zhermack ZA 22 Blue [2 kg Set]","offer_id":55087252668757,"sku":"S82327","price":89.95,"currency_code":"EUR","in_stock":false},{"title":"Zhermack ZA 22 Blue [10 kg Set]","offer_id":55087252701525,"sku":"S82324","price":389.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0896\/4096\/0341\/files\/Logo_Zhermack.png?v=1762179478","url":"https:\/\/siliconesandmore.com\/en\/products\/zhermack-za-22-mould-blauw-blauwe-platina-additiesilicone-voor-matrijzenbouw-beton","provider":"siliconesandmore","version":"1.0","type":"link"}
