The mixing ratio is 1:1 by weight. Due to its high hardness and mechanical resistance, HT 45 is suitable for dimensionally stable molds of small, highly detailed objects with thin walls.\u003c\/p\u003e\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eShore A 45:\u003c\/strong\u003e a firm, dimensionally stable mold that does not deform easily during casting.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eTear strength 15 N\/mm:\u003c\/strong\u003e suitable for repeated use.\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\u003ePrecision in reproduction:\u003c\/strong\u003e suitable for fine details and thin surfaces.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMixing ratio 1:1:\u003c\/strong\u003e easy to weigh, no complex calculations.\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 mechanical resistance, dimensional stability, and precision are important.\u003c\/li\u003e\n\n\u003cli\u003eJewelry and small precision parts.\u003c\/li\u003e\n\n\u003cli\u003eRapid prototyping of small, highly detailed objects with thin walls, such as turbine components.\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 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 plastilines, 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 45 Translucent [2 kg Set]","offer_id":55087433089365,"sku":"S82335","price":89.95,"currency_code":"EUR","in_stock":false},{"title":"Zhermack HT 45 Translucent [10 kg Set]","offer_id":55087433122133,"sku":"S82332","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-45-translucent","provider":"siliconesandmore","version":"1.0","type":"link"}
