The mixing ratio is 1:1 by weight. With a tear strength of 20 N\/mm and an elongation at break of 460%, the cured silicone is strong and durable, while the translucent mold allows you to see the model inside.\u003c\/p\u003e\n\u003ch3\u003eKey advantages\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 undercut shapes.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eShore A 33:\u003c\/strong\u003e firmer than ZA 13 and ZA 22, for molds that need to retain their shape.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eElongation at break 460%:\u003c\/strong\u003e ample margin during demolding.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eStable mechanical properties:\u003c\/strong\u003e the cured rubber retains its properties in the long term.\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\u003eTranslucent:\u003c\/strong\u003e you can see the model through the mold.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eMold making where dimensional stability and precise reproduction count.\u003c\/li\u003e\n\n\u003cli\u003eJewelry and small precision parts.\u003c\/li\u003e\n\n\u003cli\u003eArtificial stone and concrete forms, thanks to good compatibility with concrete formulas.\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 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 plastelines, condensation silicones, and certain 3D printing materials. The TDS also warns that some petroleum jellies can hinder curing. When in doubt, perform a small test first. Ensure the surface is clean, grease-free, and dry.\u003c\/p\u003e","brand":"Zhermack","offers":[{"title":"Zhermack HT 33 Translucent [2 kg Set]","offer_id":55087382233429,"sku":"S82331","price":89.95,"currency_code":"EUR","in_stock":false},{"title":"Zhermack HT 33 Translucent [10 kg Set]","offer_id":55087382266197,"sku":"S82328","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-ht-33-translucent","provider":"siliconesandmore","version":"1.0","type":"link"}
