Flexible Epoxy is widely used for Structural repair, Composites, Marine. It provides reliable performance when surfaces are prepared correctly. Always follow manufacturer recommendations for safety and cure time.
Technical Specifications & Properties
Flexible Epoxy adhesives feature a Epoxy resin systems base, which provides medium curing performance. Typical cure times range from 230 to 250 minutes depending on environmental conditions, surface materials, and application thickness. The semi-flexible flexibility characteristic provide strong, rigid bonds suitable for structural applications requiring maximum strength. With high water resistance, these products perform reliably in wet environments, outdoor applications, and marine settings where moisture exposure is a concern. The 30-minute working time provides adequate opportunity for positioning and alignment before the adhesive begins to set.
Common Applications & Project Types
Flexible Epoxy adhesives excel in Structural repair, Composites, Marine. Common uses include Boat repair, Industrial bonding, DIY reinforcement, and many other professional and DIY projects. When selecting flexible epoxy for your project, consider the specific materials being bonded, environmental conditions, expected loads, and required durability. Surface preparation is critical: ensure all bonding surfaces are clean, dry, and free from oils, dust, or contaminants that could interfere with adhesion. Apply the adhesive according to manufacturer specifications, maintain appropriate clamping pressure during curing, and allow full cure time before subjecting bonds to stress or load.
Application Guidelines & Safety
Proper application techniques significantly impact bond strength and longevity when working with flexible epoxy.With a typical cure time of 240 minutes, allow sufficient time for positioning materials, but once initial bonding occurs, repositioning becomes difficult. Temperature and humidity affect curing performance: ideal conditions typically range from 15-25°C with moderate humidity levels. Storage recommendations include keeping containers sealed tightly in a cool, dry location away from extreme temperatures and direct sunlight. Always follow manufacturer safety guidelines, work in well-ventilated areas when necessary, and use appropriate personal protective equipment as recommended. Dispose of unused product and containers according to local regulations for chemical waste management.

Application Guidelines & Safety
Surface Preparation: Before applying flexible epoxy, ensure surfaces are clean, dry, and free from dust, grease, or loose particles. Proper surface preparation significantly improves bond strength and longevity.
Application Technique: Apply adhesive evenly to avoid weak spots or excess buildup. You have approximately 30 minutes of working time to position materials before initial set occurs.
Curing & Handling: Allow 240 minutes for full cure before subjecting the bond to stress. Temperature and humidity can affect curing speed and final bond strength.
Safety Considerations: Always work in a well-ventilated area. Wear appropriate protective equipment including gloves and eye protection. Avoid skin contact and inhalation of fumes. Store adhesive in a cool, dry place away from direct sunlight. Read and follow all manufacturer safety data sheets (SDS) before use.
