6 Vacuum Infusion Lower styrene emissions Improved strength Reduced weight More consistent Better cure Choice of resin systems Video available on stand C6 showing infusion with Scott Bader products

7 Structural Adhesives More efficient production Lower styrene emission Scott Bader Products Crestomer Structural Adhesives Crestabond Methacrylate Adhesives

8 Crestomer Structural Adhesives First introduced in the mid 1980 s Based on UNIQUE Scott Bader Urethane Acrylate chemistry Tough, flexible materials Base resin elongation >100% Development of a range of materials for different applications Revolutionised the marine industry and design approaches taken

9 Why Crestomer Structural Adhesives Crestomer bonding gives substrate failure, not cohesive or adhesive failure Styrene based adhesives with familiar odour Demonstrate low exotherm during cure Low risk of print through Range of gel and curing times Ease of application Faster application = Lower cost Cost effective

10 Crestomer Family Crestomer 1152PA High performance structural adhesive for filleting bulk heads, stringer sets, liners Crestomer 1153PA Long open time version of 1152PA Crestomer Advantage 30 Version of 1152PA supplied in cartridges Crestomer 1186PA Multi-purpose structural adhesive Crestomer 1196PA Lightweight (SG 0.6), core bonding adhesive

11 Crestomers Where to use Suitable Substrates FRP/GRP: Polyester Resin DCPD Vinyl Ester Epoxy Wood Marine Ply Balsa Metals Mild steel Stainless steel Galvanized steel Aluminium Brass Copper Surface Preparation Standard recommendation: Solvent wipe / Abrade / Solvent wipe

12 Crestomer 1152PA and 1153PA High Performance Structural Adhesive Stringer Sets Modular Liners Bulk Head Filleting Wind Blades General Purpose Bonding Tensile Strength > 25MPa Tensile Elongation > 100% Good Flexibility + Good Strength = Good Fatigue Resistance

Bulk Head Bonding using Crestomer FRP bulkhead to FRP CSM Overlay (3 x 600g/m²) Peak load 1200N, Deflection @ Peak load 4mm 10mm 1152PA fillet with no overlay

13 Bulk Head Bonding using Crestomer FRP bulkhead to FRP CSM Overlay (3 x 600g/m²) Peak load 1200N, Peak load 4mm 10mm 1152PA fillet with no overlay Peak load 1400N, Peak load 10mm 20mm 1152PA fillet with no overlay Peak load 3400N, Peak load 23mm, Limit of test rig, material not broken

14 Crestomer 1186PA Multi-Purpose Structural Adhesive High gap fill with low exotherm = No print through on finished part Highly Filled Material Cost effective for large quantities Tensile Strength > 12 MPa Gives strong bonds Tensile Elongation - 6% Lower elongation due to high filler rate Bonds to GRP, Wood & Metals*

15 Crestomer 1196PA Core bonding adhesive Reduces print through from foam cores Density of 1196PA = 600kg/m³ = very lightweight Tensile strength 8.6MPa Normal density foam / balsa cores (up to 200kg/m³) failure occurs in core Tests performed with high density foam (400kg/m³) - failure in the FRP skin

16 Crestomer summary Crestomer structural adhesives are proven in the GRP/FRP industry History of 3 rd party testimony Improved joint performance Excellent gap filling Excellent core bonding materials Improved structural design through tough, strong joints High fatigue loadings ensure longevity of bond Shock load protection to vital structural bonds Low VOC emissions Low exotherm meaning no print through issues

17 Partner Scott for Bader excellence Adhesives in Composite Crestabond materials

18 Crestabond Characteristics Two component Methacylate based structural adhesives Minimal surface preparation needed surfaces must be clean and dry No primer required on metal substrates Room temperature cure Cure speeds to fit most manufacturing processes Ability to bond dissimilar substrates Gap fill from 1mm 50mm Marine approval in progress

19 Crestabond Characteristics Strong with excellent fatigue resistance High elongation reducing stress on parts Resistant to water and many common chemicals Service temperature from -50 to +100 C E.G. A bonded part that is in close proximity to an engine must not be exposed to constant temperatures over 100 C otherwise the bond may fail

20 Crestabond Range Crestabond M1 series (10:1) Range of fixture times from 5 to 90 minutes Crestabond M7 series Fixture times of 5 and 15 minutes Developed to bond difficult substrates - SMC, DMC & pultruded GRP - Nylon - Zinc coated metals - Galvanised steel - Copper & copper plated - Chrome plated Crestapol modified MMA Unique technology to Scott Bader Offers Excellent adhesion to difficult substrates Good elongation, fatigue and impact performance

21 Substrates MMA s Will Structurally Bond Aluminium Stainless steel Mild steel Coated metals, EPC, PPC anodized, passivated Zinc / galvanised coated metals Polycarbonate ABS Acrylics PVC DCPD, PDCPD * Phenolic * Composites: Polyester, Epoxy, Vinylester, Carbon. Nylon 6 * * Denotes preparation may be needed

22 Case Study - Ribcraft Production of 2012 Olympic Security and Rescue Boats Crestabond M1-30 Bulk dispenser used Selection Criteria High Tensile strength Speed of use Boats bonded with no mechanical fixing Efficient manufacturing process Increased production capacity
