Epoxy Core-Shell Rubber Toughener MX-154, Nano CSR in Bisphenol A Epoxy for Structural Adhesive Composite

Name: Epoxy Core-Shell Rubber Toughener MX-154, Nano CSR in Bisphenol A Epoxy for Structural Adhesive Composite
Rating: 4.9 (88 reviews)

MX‑154 is a ready‑to‑use liquid toughening masterbatch containing nano‑sized core‑shell rubber (CSR) uniformly predispersed within bisphenol‑A epoxy resin carrier. The fine nano rubber phase removes the necessity for high‑shear grinding and lengthy dispersion work at customer formulation sites. When incorporated into epoxy matrix, MX‑154 boosts fracture toughness, peel strength and cyclic fatigue resistance. It retains favorable thermal‑resistance and glass‑transition temperature of cured epoxy

Product Detail

Product Detail PageChemical IdentityMX‑154 is a predispersed epoxy‑based masterbatch utilizing nano‑scale core‑shell rubber particles produced via controlled emulsion polymerization. Nano CSR rubber particles are homogenously suspended inside standard bisphenol‑A liquid epoxy resin. There is no agglomeration of rubber phase inside the supplied liquid product. The epoxy carrier demonstrates excellent compatibility with conventional bisphenol‑A epoxy resins and works well with mainstream curing chemistries including amine, dicyandiamide and anhydride hardeners. It is delivered as a viscous liquid, allowing straightforward blending into base epoxy resin without pre‑milling or extra pretreatment prior to formulation.

Key PerformanceWithin the cross‑linked rigid epoxy network after curing, finely distributed nano‑CSR domains function as energy‑absorbing micro‑zones. Subjected to external mechanical stress, these nano rubber particles initiate localized plastic deformation, dissipate fracture energy and effectively block crack expansion. Compared to larger‑sized CSR variants, MX‑154’s nano particle size helps to deliver smoother surface finish on cured composite laminates with reduced surface speckle defects. It significantly enhances peel strength and fatigue life of epoxy structural adhesives. Composite laminates modified with MX‑154 exhibit superior resistance against thermal shock and repeated hot‑cold cycling, minimizing the initiation of harmful micro‑cracks. The glass‑transition temperature and heat‑deflection performance of cured epoxy do not suffer sharp drop after incorporation. The masterbatch maintains suitable viscosity, supporting stable processing for prepreg manufacturing, resin infusion and automated adhesive dispensing operations.

ApplicationsMX‑154 is applicable for both one‑part and two‑part epoxy structural adhesives dedicated to metal‑composite dissimilar‑substrate bonding. It serves as a high‑performance modifier for carbon‑fiber and glass‑fiber reinforced epoxy composites. Typical finished articles cover lightweight transportation structural components, industrial composite panels, machinery structural parts which are exposed to alternating temperature and cyclic mechanical loads. It is well‑suited for multiple composite fabrication technologies, including prepreg processing, vacuum resin infusion, and hand‑lay‑up lamination. This toughener is widely selected when formulating high‑reliance bonding adhesives for heavy‑duty mechanical assembly.

Storage & HandlingKeep MX‑154 stored in hermetically sealed original drums inside cool, dry warehouse, recommended storage temperature 15‑25℃. Extended hot storage should be avoided, otherwise slow viscosity drift may occur. Under cold conditions the product will thicken; mild, gradual warming prior to use is permitted. Shield the material from direct solar radiation. After drum opening, reseal the container tightly without delay to prevent moisture ingress. Ensure sufficient local ventilation during material transfer and compounding work. Operators shall wear protective gloves, safety goggles and protective garments to avoid direct skin and eye exposure.
