Its relatively low initial mixed viscosity gives easy wet-out of heavyweight reinforcements, making it a strong choice for thick or multi-layer fiberglass and carbon layups. It cures to a tough, high-strength matrix at room temperature and reaches its full mechanical and thermal performance with a simple low-temperature postcure.\u003c\/p\u003e\n\u003ch3\u003eAt a Glance (Standard Hardener)\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eMix ratio\u003c\/th\u003e\n\u003ctd\u003e100:26 by weight (100:31 by volume)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMixed density\u003c\/th\u003e\n\u003ctd\u003e1.10 g\/cm³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePot life (150 g, 25°C)\u003c\/th\u003e\n\u003ctd\u003e1 hr 10 min–1 hr 30 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVacuum bagging window\u003c\/th\u003e\n\u003ctd\u003e2 hr 20 min–3 hr 05 min after mixing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEarliest demold\u003c\/th\u003e\n\u003ctd\u003e6 hr 35 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCure schedule\u003c\/th\u003e\n\u003ctd\u003eAmbient cure at 18°C minimum; full properties with 16 hrs at 50°C or 5 hrs at 70°C postcure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGlass transition temperature (Tg)\u003c\/th\u003e\n\u003ctd\u003e60°C ambient cure; up to 89°C postcured\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTensile strength (cured resin)\u003c\/th\u003e\n\u003ctd\u003e50.8 MPa ambient; up to 77.3 MPa postcured\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlexural strength (cured resin)\u003c\/th\u003e\n\u003ctd\u003e99.9 N\/mm² ambient; up to 126 N\/mm² postcured\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShelf life\u003c\/th\u003e\n\u003ctd\u003e36 months when stored at 10–25°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eChoose Your Working Time\u003c\/h3\u003e\n\u003cp\u003eAmpreg 30 ships with three Ampreg 3X hardener speeds, so you can match pot life to the size and complexity of the layup:\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eHardener speed\u003c\/th\u003e\n\u003cth\u003ePot life (150 g, 25°C)\u003c\/th\u003e\n\u003cth\u003eBest for\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFast\u003c\/td\u003e\n\u003ctd\u003e30–40 min\u003c\/td\u003e\n\u003ctd\u003eSmall parts, thin layups, and quick turnaround\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003ctd\u003e1 hr 10 min–1 hr 30 min\u003c\/td\u003e\n\u003ctd\u003eGeneral-purpose hand layup\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlow\u003c\/td\u003e\n\u003ctd\u003e3 hr 40 min–4 hr 20 min\u003c\/td\u003e\n\u003ctd\u003eLarger layups requiring more working time\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eSpecialty extra slow and Ultra-Slow and High Tg hardeners are also available for extended open time and elevated-temperature service, respectively.

Its low initial mixed viscosity makes it especially well suited to wetting out heavyweight fabrics and multi-ply laminates.\u003c\/p\u003e\n\u003ch4\u003eWhat is the mix ratio for Ampreg 30?\u003c\/h4\u003e\n\u003cp\u003eAmpreg 30 resin and Ampreg 3X hardener mix at 100:26 by weight (100:31 by volume) across the Fast, Standard, Slow, and Extra-Slow hardener speeds.\u003c\/p\u003e\n\u003ch4\u003eHow long does Ampreg 30 take to cure?\u003c\/h4\u003e\n\u003cp\u003eWith Standard hardener, pot life runs about 1 hr 10 min to 1 hr 30 min, and the laminate can be demolded in as little as 6 hr 35 min at room temperature. Full mechanical and thermal properties develop after a postcure of either 16 hours at 50°C or 5 hours at 70°C.\u003c\/p\u003e\n\u003ch4\u003eIs Ampreg 30 low-VOC or low toxicity?\u003c\/h4\u003e\n\u003cp\u003eAmpreg 30 uses Gurit's low-toxicity Ampreg 3X hardener range, selected to improve health and safety compared with older-generation hardeners. Standard epoxy PPE, including nitrile gloves, eye protection, and adequate ventilation, is still required. See the full Safety Data Sheet before use.\u003c\/p\u003e\n\u003ch4\u003eWhat is the difference between Ampreg 30 and Ampreg 31?\u003c\/h4\u003e\n\u003cp\u003eBoth are low-toxicity Gurit epoxy laminating systems with the same 100:26 mix ratio and hardener speed lineup. Ampreg 30 has a lower initial mixed viscosity, making it easier to wet out heavyweight reinforcements. Ampreg 31 is viscosity-optimized to balance good wet-out with drainage resistance, making it better suited to vertical and overhead surfaces.\u003c\/p\u003e","brand":"Gurit","offers":[{"title":"Ampreg 30 resin- Quart","offer_id":50653247406317,"sku":"AMP30-A","price":25.49,"currency_code":"USD","in_stock":true},{"title":"Ampreg 30 resin- Gallon","offer_id":50653264380141,"sku":"AMP30-B","price":95.4,"currency_code":"USD","in_stock":true},{"title":"Ampreg 3X Fast Hardener- 1\/2 pint","offer_id":50653268607213,"sku":"AP3XF-A","price":5.31,"currency_code":"USD","in_stock":true},{"title":"Ampreg 3X Standard Hardener- 1\/2 pint","offer_id":50653275160813,"sku":"AP3XR-A","price":4.86,"currency_code":"USD","in_stock":true},{"title":"Ampreg 3X Slow Hardener- 1\/2 pint","offer_id":50653280436461,"sku":"AP3XS-A","price":4.64,"currency_code":"USD","in_stock":true},{"title":"Ampreg 3X Fast Hardener- quart","offer_id":50653285384429,"sku":"AP3XF-B","price":21.23,"currency_code":"USD","in_stock":true},{"title":"Ampreg 3X Standard Hardener- quart","offer_id":50653293379821,"sku":"AP3XR-B","price":19.42,"currency_code":"USD","in_stock":true},{"title":"Ampreg 3X Slow Hardener- quart","offer_id":50653303537901,"sku":"AP3XS-B","price":18.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/7415\/7805\/files\/AMP30-A-Ampreg-Epoxy-Laminating-System.png?v=1789058899","url":"https:\/\/www.fibreglast.com\/products\/ampreg-30-low-viscosity-epoxy-wet-laminating-resin","provider":"Fibre Glast","version":"1.0","type":"link"}
