Vinyl Ester Resin Revision date: August 2015 Technical Data Sheet Water Barrier & Bonding Water Barrier & Structure Fabrication • Premium resin for tooling applications • Superior blister resistance • Excellent resistance to impact, thermal and demolding cracks PRODUCT DESCRIPTION Suitable for fabricating small to large FRP structures with high production rates at room temperature. Vinyl Ester Resin is formulated for curing at room temperature with methyl ethyl ketone peroxide. Suitable for either hand-layup or spray-up. FEATURES & BENEFITS • Versatile • Premium resin for tooling applications • Versions available for marine skincoat, bulk build and acrylic bonding • Lower exotherm versions for thicker laminates • Quick cure versions available • Low water absorption rate • Superior blister resistance • High strength and toughness • Excellent resistance to impact, thermal, and demolding cracks • Tack free surface • Faster lamination and build-up of layers • Improved profile • Minimized print-through for smooth surfaces • Wets out reinforcements rapidly • Minimized voids and resin-starved areas • Easy maintenance of resin-to-glass ratio • High heat distortion temperature • Retention of physical properties at elevated temperatures • Thixotropic • Resistance to sagging and draining • Stable gel time • Consistent gel and cure time at various catalyst levels • Manufactured using statistical process and quality controls • Consistent performance, batch to batch (Page 1 of 2) NEW NAUTICAL COATINGS, INC. 14805 49th Street North • Clearwater, FL 33762 • 727.523.8053

Vinyl Ester Resin Technical Data Sheet SeaNj^ HawkisK-PREMIUM YACHT FINISHES HANDLING The addition of MEKP will induce gel and cure at room temperature. As with all polyesters, rate and degree of cure are functions of initiator concentration and of temperature. Resin and work area should be between 24°C (75°F) and 35°C (95°F) to ensure satisfactory results. Initiator levels should be within a range of 1.0-2.5% based on weight of resin. The use of initiator levels outside of this range may result in an inadequate cure, with laminates exhibiting moderate to severe post-cure after demolding....
