MGS LR335 Epoxy Laminating Resin (Gallon/net 4.38 Kg)
The MGS LR335 laminating resin system is an epoxy resin designed for high-performance use with glass, carbon, and aramid fibers. Its pot life ranges from approximately 10 minutes to 6-7 hours, depending on the hardener used.
$166.99
MGS L 335 is a laminating epoxy resin system with versatile hardener options (335, 340) that provide varied pot lives to suit different processing needs. This resin is tailored for applications requiring strong physical and mechanical properties
When mixed with MGS Hardeners 335 or 340, MGS LR335 offers exceptional durability and compatibility with various fibers, creating high-strength, non-tacky surfaces upon curing. It supports high static and dynamic loads, even under diverse environmental conditions, making it ideal for applications needing robust, heat-resistant surfaces. This system can be used without heat treatment for non-aircraft applications, though full performance properties are achieved after heat treatment.
Application
- Gliders
- Motor Gliders
- Sports Equipment
- Model Airplanes
- Molds and Tools
Mixing and Preparation
- Mixing Ratio: 100 parts resin to 38 ± 2 parts hardener by weight or 45 ± 2 parts by volume (for both 335 and 340).
Application Techniques
Wet Layup
- Description: Resin is applied directly to the reinforcement materials.
- Best For: Prototyping and small-scale projects.
Vacuum Bagging
- Description: Combines wet layup with vacuum pressure to improve laminate quality.
- Common Uses: Aerospace, marine, and automotive industries where high strength and precision are critical.
Application Tip: Mix the resin until it is completely clear with no cloudiness. Avoid over-mixing or under-mixing, as either can compromise the curing process.
Processing Temperature
- Processing time is approximately 2–3 hours at 20°C–25°C for Hardener 335 and 8–9 hours at 20°C–25°C for Hardener 340, with a recommended temperature range of 10°C to 50°C and an optimal range of 20°C to 40°C.
Curing Process
- Initial Curing: Curing occurs at room temperature.
- Heat Treatment: A heat treatment at 50–55°C (122–131°F) is recommended to optimize the material's performance.
