SCIGRIP SG23HV is a high performance, high viscosity structural adhesive engineered for demanding large-scale bonding applications across the marine, transportation, and construction industries.
SG230HV
The long open time choice for large structural bonding
Ideal for
Overview
Trusted by manufacturers of commercial and recreational vessels, buses, coaches, and composite infrastructure worldwide.
Designed to bond composites and plastics including large and irregular assemblies — SG230HV delivers the working time, gap-filling capability, and structural strength needed for the most challenging production environments. From bonding deck-to-hull assemblies and large structural frames to securing panels, hatches, and composite components, SG230HV performs where others can’t. Its unique high viscosity formula stays put on vertical and overhead surfaces, even in large bead sizes, without sagging or loss of bond performance.
Certified by Lloyd’s Register Type Approval and approved by DNV GL, SG230HV meets the rigorous quality standards demanded by marine and composite manufacturing — delivering flexibility, long working times, and dependable long-term performance in the harshest conditions.
Features and benefits
Bonds
Bonds a wide variety of composites, thermoplastics, and coated or primed metals — including dissimilar materials and large structural assemblies.
Surface preparation
Minimal surface preparation required — little to no pre-treatment needed for composite and plastic substrates.
Environment
Creates strong, permanent bonds with excellent resistance to chemicals, moisture, and harsh environmental conditions — including full saltwater immersion.
Low emissions
GREENGUARD certified for low chemical emissions — cures tack-free with no residual odour, supporting a cleaner, safer workplace.
Working times
Multiple working times (30, 40, 60 & 90 minutes). Select to fit your application, production workflow, and environmental conditions.
Sag
High viscosity, thixotropic formula — no slide or sag, even on vertical surfaces, overhead applications, and in large bead sizes up to 80mm.
Gap fill
Exceptional gap filling capability — fills deep, irregular gaps up to 1.5 inches (39mm), ideal for large structural assemblies.
Quality
Permanent strength and elasticity. Excellent fatigue, impact, and shock load resistance — proven in structural marine and infrastructure applications worldwide.
Recommended Use
Large-structure composite bonding — Proven performance on composites, thermoplastics, and coated or primed metals, with the long working times and gap-fill capacity to handle the biggest assemblies.
Trusted in commercial and recreational marine manufacturing — Widely used for deck-to-hull bonding, hatch and composite part assembly, lifeboat and pontoon construction, mounting hardware, hardtop bonding, and bonding boat trim on vessels of all sizes.
Used in bus and coach manufacturing — A proven solution for bonding large exterior and interior structural components, including front and rear shell bonding, roof panels, door assemblies, window frames, roof hatches, and composite body parts.
Suited to composite infrastructure and construction applications — Including bridge beams, composite repair structures, and other large-scale structural bonding projects requiring long working times and outstanding gap-filling performance.
