Orthophthalic RTM/Infusion Resin

R100I series is formulated from an orthophthalic unsaturated polyester resin specifically designed for closed-mold processes such as RTM (Resin Transfer Molding) and light-infusion.

This resin offers a balanced combination of processability, wet-out performance, and reliability, making it suitable for general-purpose composite parts manufactured through RTM or controlled infusion techniques.

Its optimized viscosity profile allows efficient mold filling and uniform reinforcement wet-out for consistent laminate construction.

Product Characteristics:

• Low to medium viscosity ideal for RTM and light-infusion processes
• Controlled gel time tailored for RTM and infusion processes
• Good wet-out of fiberglass reinforcements
• Balanced mechanical performance for general-purpose composite components
• Good adhesion between reinforcement layers
• Compatible with most gelcoats and pigments used in composite molding

Primary Applications:

R100I series is recommended for the manufacturing of composite parts requiring uniform thickness and good surface finish

Recommended Application Methods:

• RTM (Resin Transfer Molding)
• Infusion / Light-RTM
