EPIKOTE Laminating Epoxy Resin LR635
EPIKOTE™ MGS® LR635 Laminating Epoxy System
EPIKOTE™ MGS® LR635 is a versatile, high-performance epoxy laminating resin system designed for a wide range of composite applications. With a solvent-free, filler-free formulation, it delivers excellent mechanical performance and consistent processing across glass, carbon, and aramid fibre reinforcements.
Engineered for flexibility in manufacturing, LR635 can be paired with a range of EPIKURE™ curing agents to tailor reactivity—from fast cures to extended working times—making it suitable for everything from small repairs to large, complex laminations.
Key Features
- Wide range of curing speeds (approx. 10 minutes to 5+ hours pot life)
- Adjustable reactivity by selecting or blending hardeners
- Excellent mechanical strength and durability
- Compatible with glass, carbon, and aramid fibres
- Solvent-free system for high-quality laminates
- Long shelf life (up to 24 months sealed)
Performance & Processing
- Processing temperature range: 15°C – 50°C
- Cold cure capability down to ~5°C (with selected hardeners)
- Operational temperature: -40°C to +70°C after full cure
- Post-curing above 40°C required for maximum properties
Typical Applications
- Wind turbine blades (DNV approved system)
- Marine laminating and boatbuilding
- Tooling and mould construction
- Sporting goods and structural composites
- Adhesive bonding applications
Why Use LR635
LR635 is a go-to laminating system when you need process flexibility without compromising performance. Whether you’re hand laminating, vacuum bagging, or working on large builds, the ability to fine-tune cure speed makes this system extremely reliable across different shop conditions.
