The mixing ratio is 1:1 by weight. With a working time of 45 minutes at 23 °C, there is plenty of time to mix, degas, and pour in a controlled manner; the mould can be demoulded after approximately 8 hours.\u003c\/p\u003e\n\u003ch3\u003eKey advantages\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eLong working time of 45 minutes:\u003c\/strong\u003e provides room to degas and pour larger moulds in one go.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003e1:1 mixing ratio:\u003c\/strong\u003e equal amounts of base and catalyst, easy to weigh.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eLow viscosity (4,500 mPa·s):\u003c\/strong\u003e flows well around fine details.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eElongation at break 440%:\u003c\/strong\u003e ample margin when demoulding undercuts.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eTear strength 12 N\/mm:\u003c\/strong\u003e suitable for repeated use.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eTranslucent:\u003c\/strong\u003e you can see the model through the mould.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eMould making where dimensional stability and precise reproduction count.\u003c\/li\u003e\n\n\u003cli\u003eConcrete moulds and artificial stone, thanks to its good compatibility with concrete formulas.\u003c\/li\u003e\n\n\u003cli\u003ePodiatry and orthopedic impressions.\u003c\/li\u003e\n\n\u003cli\u003eMoulds 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 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 plasticines, condensation-cure silicones, and certain 3D printing materials. The TDS also warns that some petroleum jellies may hinder the curing process. In case of doubt, perform a small test first. Ensure the surface is clean, grease-free, and dry.\u003c\/p\u003e","brand":"Zhermack","offers":[{"title":"Zhermack ZA 13 Translucent [2 kg Set]","offer_id":55087192342869,"sku":"S82323","price":89.95,"currency_code":"EUR","in_stock":false},{"title":"Zhermack ZA 13 Translucent [10 kg Set]","offer_id":55087192375637,"sku":"S82320","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-13-mould-wt-45-translucent-translucide-platina-additiesilicone-voor-matrijzenbouw-beton","provider":"siliconesandmore","version":"1.0","type":"link"}
