Its \u003cstrong\u003elow exotherm formulation\u003c\/strong\u003e helps reduce shrinkage and gel coat stress during curing, making it ideal for tight radii, transitioning style lines, and fiberglass reinforced plastic (FRP) assemblies where reliable bonding performance and cosmetic quality are critical. Designed for boat builders, marine fabricators, and composite manufacturers, POLYFILL 1050 provides reliable adhesion, excellent vertical stability, and efficient processing for marine assembly and production environments.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features of POLYFILL 1050 Marine Putty \u0026amp; Radius Compound\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Shrink Formula:\u003c\/strong\u003e Minimizes shrinkage and print-through for smoother, more consistent laminate finishes.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eLow Exotherm Performance:\u003c\/strong\u003e Reduces heat buildup during curing to help minimize gel coat stress, cracking, and surface blemishes.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eExcellent Radius Compound Performance:\u003c\/strong\u003e Flows smoothly into tight radii, corners, style lines, and complex marine contours.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eStrong FRP Bonding:\u003c\/strong\u003e Provides reliable adhesion for fiberglass reinforced plastic (FRP) bonding and composite assembly applications.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eVertical Surface Stability:\u003c\/strong\u003e Maintains excellent hold on vertical surfaces without excessive sagging or movement.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eReduces Finish Work:\u003c\/strong\u003e Helps minimize sanding, repairs, and production rework for improved manufacturing efficiency.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSeries: POLYFILL 1050\u003c\/li\u003e\n  \u003cli\u003eType: Marine Putty\u003c\/li\u003e\n  \u003cli\u003eChemistry: Polyester Liquid Adhesive\u003c\/li\u003e\n  \u003cli\u003eGel Time: 18 - 24 Minutes\u003c\/li\u003e\n  \u003cli\u003eReaction Time: 16 - 30 Minutes\u003c\/li\u003e\n  \u003cli\u003eFixture Time: 34 - 54 Minutes\u003c\/li\u003e\n  \u003cli\u003eViscosity:\u003c\/li\u003e\n\u003cul\u003e\n  \u003cli\u003e720,000 - 960,000 cps @ 2 RPM\u003c\/li\u003e\n  \u003cli\u003e90,000 - 140,000 cps @ 20 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n  \u003cli\u003ePeak Exotherm: 200 - 250°F (93.3 - 121.1°C)\u003c\/li\u003e\n  \u003cli\u003eColor: Tan\u003c\/li\u003e\n  \u003cli\u003eOdor: Styrene\u003c\/li\u003e\n  \u003cli\u003eTexture: Smooth\u003c\/li\u003e\n  \u003cli\u003eWeight: 10.2 lbs\/gallon\u003c\/li\u003e\n  \u003cli\u003eTensile Elongation: 2%\u003c\/li\u003e\n  \u003cli\u003eTensile Strength: 1,620 psi\u003c\/li\u003e\n  \u003cli\u003eFlexural Strength: 2,160 psi\u003c\/li\u003e\n  \u003cli\u003eHeat Deflection: 165°F (74°C)\u003c\/li\u003e\n  \u003cli\u003eShore D Hardness: 75 - 85\u003c\/li\u003e\n  \u003cli\u003ePackage Size: 5-Gallon Pails\u003c\/li\u003e\n  \u003cli\u003eShelf Life: 6 Months\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Typical physical properties @ 75°F (24°C).\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFilling tight radii, corners, and transitioning style lines in boat molds and fiberglass laminates\u003c\/li\u003e\n  \n  \u003cli\u003eBonding fiberglass reinforced plastic (FRP) components and composite assemblies\u003c\/li\u003e\n  \n  \u003cli\u003eBedding marine core materials and structural laminate sections\u003c\/li\u003e\n  \n  \u003cli\u003eVertical surface bonding and radius filling applications\u003c\/li\u003e\n  \n  \u003cli\u003eGeneral marine bonding, assembly, and fiberglass fabrication\u003c\/li\u003e\n  \n  \u003cli\u003eMarine laminating applications requiring low shrink and low exotherm performance\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Infinity Bond","offers":[{"title":"5 Gallon Pail","offer_id":43970350088326,"sku":"INF POLYFILL 1050 PL","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/6903\/3269\/files\/infinity-bond-polyfill-1050-marine-polyester-putty-5-gallon-pail.jpg?v=1778516191","url":"https:\/\/www.infinitybond.com\/products\/infinity-bond-polyfill-1050-marine-putty","provider":"Infinity Bond Adhesives","version":"1.0","type":"link"}
