Infinity Bond POLYFILL 1050 Low Shrink Marine Polyester Putty

Low Shrink Marine Putty & Radius Compound for FRP Bonding & Boat Laminate Support Infinity Bond POLYFILL 1050 is a low shrink polyester marine putty and radius compound engineered for FRP bonding, fiberglass laminate support, and demanding boat building applications where reduced shrinkage and controlled curing performance are critical. Its low exotherm formula helps minimize print-through, gel coat stress, air voids, dry fibers, and laminate cracking to improve laminate consistency and cosmetic finish quality in marine fabrication environments. Designed for tight radii, style line transitions, and structural marine assembly applications, POLYFILL 1050 delivers dependable bonding performance with excellent vertical stability while helping reduce sanding, repairs, and secondary finish work during production. Performance Benefits of POLYFILL 1050 Marine Putty & Radius Compound Low Exotherm Formula: Helps reduce heat buildup during curing for improved laminate consistency Reduced Shrinkage Characteristics: Minimizes print-through and gel coat stress during fabrication Designed for Tight Radii: Supports clean laminate formation in style lines, corners, and complex marine contours FRP Bonding Performance: Helps reduce air voids and dry fibers in fiberglass and composite assemblies Vertical Surface Stability: Maintains reliable hold on vertical and contoured applications Smooth Processing Properties: Supports efficient marine fabrication and composite assembly workflows Reduced Finish Work: Helps minimize secondary sanding, repairs, and production rework Resilient Bond Line Performance: Supports demanding marine fabrication and structural bonding applications Specifications Series: POLYFILL 1050 Type: Marine Putty Chemistry: Polyester Liquid Adhesive Gel Time: 18 - 24 Minutes Reaction Time: 16 - 30 Minutes Fixture Time: 34 - 54 Minutes Viscosity: 720,000 - 960,000 cps @ 2 RPM 90,000 - 140,000 cps @ 20 RPM Peak Exotherm: 200 - 250°F (93.3 - 121.1°C) Color: Tan Odor: Styrene Texture: Smooth Weight: 10.2 lbs/gallon Tensile Elongation: 2% Tensile Strength: 1,620 psi Flexural Strength: 2,160 psi Heat Deflection: 165°F (74°C) Shore D Hardness: 75 - 85 Package Size: 5-Gallon Pails Shelf Life: 6 Months Note: Typical physical properties @ 75°F (24°C).
