When injected into wet cracks, it reacts with water to produce a closed-cell foam.\u003c\/p\u003e\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\u003cp\u003eUltra is used in water-related structures to form an inert, non-toxic permanent seal. Its cured elongation of 300% suits leaking cracks or joints where movement may occur, while the hydrophobic foam maintains its physical form through wet and dry cycles.\u003c\/p\u003e\n\u003cp\u003eThe system consists of Ultra base resin and MG Accelerator “B”. The accelerator allows an experienced installer to adjust the reaction profile according to job-site temperature and the amount of moisture encountered.\u003c\/p\u003e\n\u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e650 cps viscosity:\u003c\/strong\u003e Moderate-viscosity base resin that pumps as a single component after the accelerator has been added.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e300% elongation:\u003c\/strong\u003e Supports use in leaking cracks and joints where some movement is possible.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpands up to 25 times:\u003c\/strong\u003e The reacting polyurethane foam can expand up to 25 times its initial volume.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e224 kg\/m³ cured density:\u003c\/strong\u003e Measured in accordance with ASTM D-1622.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e300 psi tensile strength:\u003c\/strong\u003e Measured in accordance with ASTM D-638.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAdjusting the reaction time\u003c\/h3\u003e\n\u003cp\u003eAt 25°C, adding MG Accelerator “B” at 1.25%—equivalent to 1\/2 pint per five gallons—produces an expansion start time of about 50 seconds and completion in about five minutes after contact with water.\u003c\/p\u003e\n\u003cp\u003eAt 25°C, adding MG Accelerator “B” at 2.5%—equivalent to one pint per five gallons—produces an expansion start time of about 30 seconds and completion in about three minutes after contact with water.\u003c\/p\u003e\n\u003ch3\u003eJob-site conditions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe reaction profile is affected by temperature and the amount of moisture encountered.\u003c\/li\u003e\n\u003cli\u003eMG Accelerator “B” is intended to be used by an experienced installer to adjust the reaction profile before pumping.\u003c\/li\u003e\n\u003cli\u003eThe stated reaction times were determined at 25°C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Green Mountain International","offers":[{"title":"4 Kg","offer_id":48702030250176,"sku":"INJULTRAAERA\/4","price":187.62,"currency_code":"AUD","in_stock":true},{"title":"20 Kg","offer_id":48702030282944,"sku":"INJULTRAAERA\/20","price":582.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0507\/3630\/0224\/files\/moutaingroutultra.png?v=1785472179","url":"https:\/\/adheseal.com.au\/products\/mountain-grout-ultra","provider":"Adheseal","version":"1.0","type":"link"}
