Large amounts of material cast at one time will generate mild heat and will shrink in proportion to mass. The more material cast in a large concentration, the higher the shrinkage.

If encapsulating an object, do not pour the mixture directly over the object. Let the mixture seek its level. A uniform flow will help minimize entrapped air.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eFor Best Results\u003c\/strong\u003e - \u003c\/em\u003eBest results are obtained using a pressure casting technique. After pouring the mixed compound, the entire casting assembly (mold, dam structure, etc.) is placed in a pressure chamber and subjected to 60 PSI (4.2 kg \/ cm2 ) air pressure for at least two hours. For most applications, room temperature curing (73°F \/ 23°C) for 24–48 hours is adequate. Castings will reach ultimate physical properties at room temperature in 5–7 days.\u003c\/p\u003e\n\u003cul class=\"docslist\"\u003e\n\u003cli\u003e\n\u003ch3\u003eTechnical and Related Documents\u003c\/h3\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003ca class=\"primary-trim\" href=\"http:\/\/www.smooth-on.com\/tb\/files\/CLEAR_FLEX_30_TB.pdf\" target=\"_blank\"\u003eTechnical Bulletin\u003c\/a\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003eSafety Data Sheets\u003c\/h3\u003e\n\u003cdiv data-reg=\"US\" data-lang=\"EN\"\u003e\n\u003cdiv\u003e\u003ca href=\"http:\/\/www.smooth-on.com\/msds\/files\/Clear_Flex_30.pdf\" target=\"_blank\"\u003eClear Flex 30 SDS \u003cspan class=\"sdslang\"\u003e| English\u003c\/span\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Smooth-On","offers":[{"title":"Trial Kit (1.95 lbs. \/ 0.88 kg.)","offer_id":48015598813499,"sku":"54144","price":62.99,"currency_code":"USD","in_stock":true},{"title":"2 Gallon Kit (15.6 lbs. \/ 7.08 kg.)","offer_id":48015598780731,"sku":"54161","price":279.99,"currency_code":"USD","in_stock":false},{"title":"10 Gallon Kit (78 lbs. \/ 35.38 kg.)","offer_id":48015598747963,"sku":"54171","price":1086.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/7539\/6411\/files\/ClearFlex-30-combo-1400x1050.jpg?v=1748699096","url":"https:\/\/maacaffestore.com\/products\/clear-flex-30","provider":"The Compleat Sculptor, Inc","version":"1.0","type":"link"}
