CYCOM 5250-4 RTM is a true one-part, homogeneous BMI resin developed specifically for the resin transfer molding (RTM) process. It reaches very low viscosity during transfer and maintains a low viscosity for several hours, thus providing the maximum capability to fabricate complex parts. Laminates fabricated from CYCOM 5250-4 RTM are capable of service temperatures up to 400°F (204°C); but, its toughness and processability make it an ideal material for 180°F (82°C) temperature applications where epoxies are commonly used.

CYCOM 5250-4 RTM offers the highest open hole compression (OHC) value of any organic matrix resin while providing the highest level of toughness available in an RTM capable matrix resin.
