Laminating Resins

Makobond LR-375 is an unfilled amber epoxy laminating system designed for high-service-temperature applications. It features an extended working time, enabling processes like vacuum-bagging, yet sets sufficiently at room temperature for easy demolding of the laminate for post-curing. LR-375 offers a long tool life suitable for autoclave service temperatures up to 450°F. It excels at wetting out carbon and fiberglass tooling fabrics, ensuring thorough impregnation. LR-375 is ideal for producing composite parts for high-temperature service, offering exceptional thermal resistance.

Makobond LR 356 is a high temperature unfilled laminate resin designed for composite tools. LR 356 has a relatively low mixed viscosity that helps with wet out of fabrics. This system produces parts with excellent heat resistance making it the ideal laminate system for high temperature service.

Makobond LR-310 resin, suitable for marine applications, features low viscosity for quick wetting of reinforcing fabrics during lamination, allowing rapid fabrication. It easily incorporates bulk fillers or reinforcements and effectively penetrates wood surfaces, providing stronger, rot-resistant surfaces. LR-310 resin is formulated for excellent moisture resistance, ideal for items exposed to moisture or high humidity. Once cured, LR-310 materials exhibit high heat resistance for long-term stability, making it a highly engineered product for stable, high-performance structures or repairs.

Makobond LR 308 is a low viscosity, unfilled laminate resin designed to service a variety of production parts and its components. The low viscosity is ideal for a fast wet out of fabrics for production parts. LR 308 is an easy-to-use product that produces parts with a long service life.

Makobond LR-305 is a low viscosity laminate resin designed for composite parts and structural production. LR-305 provides a 1-hour pot life and will completely cure at room temperature. Other applications for LR-305 include aircraft, radomes, auto bodies, and prototyping. LR-305 also allows the addition of various additives to promote desired properties like adhesion. Fully cured Tg is 203°F (95°C).

Makobond LR 325 is a white room temperature laminate resin designed to produce durable tools. The LR 325 system provides deep penetration of various fabrics and leaves no voids in tools. LR 325 has excellent chemical resistance making it ideal for most applications.
