Epoxy Core-Shell Rubber Toughener MX-154, Nano CSR in Bisphenol A Epoxy for Structural Adhesive Composite
MX‑154 is a liquid epoxy toughening masterbatch with finely dispersed nano‑sized core‑shell rubber (CSR) particles within bisphenol‑A epoxy carrier resin. The nano‑scale CSR particles eliminate labor‑intensive high‑shear grinding during epoxy compounding. This toughener effectively enhances fracture toughness, peel strength and fatigue performance of cured epoxy systems, while maintaining original thermal‑resistance and glass‑transition temperature. MX‑154 is formulated for high‑end structural a
Product Detail PageChemical IdentityMX‑154 consists of nano‑dimension core‑shell rubber particles uniformly predispersed in standard bisphenol‑A liquid epoxy resin. The rubber core‑shell particles are produced via emulsion polymerization with controlled nano particle‑size distribution. The nano CSR is already well distributed inside the epoxy carrier, so formulators do not require additional high‑energy milling operations. The base bisphenol‑A epoxy carrier offers excellent miscibility with common liquid epoxy resins and is compatible with amine, dicyandiamide and anhydride curing agents. Supplied as viscous liquid, MX‑154 can be directly blended into epoxy base resin during formulation work without pre‑treatment.
Key PerformanceAfter epoxy curing, embedded nano‑CSR particles act as micro energy‑absorbing sites inside the rigid cross‑linked epoxy network. Under external mechanical load, these nano rubber particles dissipate fracture energy and halt crack propagation. Thanks to its finer nano particle size compared with conventional CSR grades, MX‑154 delivers improved surface quality for cured composite parts with fewer surface defects. It significantly increases peel strength and fatigue resistance of structural adhesives. Thermal‑shock and thermal‑cycling durability of composite laminates are enhanced, suppressing micro‑crack formation under alternating hot‑cold conditions. Notably, the glass‑transition temperature and heat‑resistance of the cured epoxy matrix do not undergo substantial decline after addition of MX‑154. Its moderate viscosity contributes to good processability for resin infusion, prepreg production and automatic adhesive dispensing.
ApplicationsMX‑154 is suitable for modification of one‑component and two‑component epoxy‑based structural adhesives used for metal‑to‑composite bonding. It is widely deployed in high‑performance fiber‑reinforced composite systems including carbon‑fiber and glass‑fiber composite laminates. Typical end‑uses include transportation lightweight structural parts, industrial composite panels, and composite components requiring outstanding fatigue‑resistant performance. MX‑154 fits prepreg formulation, resin infusion and hand‑lay‑up composite manufacturing processes. It is also applicable for high‑strength bonding adhesives for machinery assembly where long‑term thermal cycling endurance is demanded.
Storage & HandlingStore MX‑154 in tightly sealed original drums inside dry and cool warehouse; recommended storage temperature ranges 15‑25℃. Avoid long‑term storage under high ambient temperature, which may cause gradual viscosity rise. Low‑temperature storage may increase viscosity, gentle warming before usage is acceptable. Prevent direct sunlight. Once the drum is opened, reseal the container promptly to avoid moisture contamination. Maintain adequate local ventilation during material transferring and formulation operations. Wear suitable gloves, goggles and protective clothing to prevent direct skin and eye contact.
