MX‑153 is a liquid core‑shell rubber (CSR) toughening masterbatch with nano‑sized rubber particles pre‑dispersed inside bisphenol‑A epoxy resin carrier. It eliminates complicated high‑shear dispersion work during epoxy formulation. This toughener effectively upgrades fracture toughness, peel strength and thermal‑cycle performance, while largely preserving the original thermal resistance and modulus of cured epoxy systems. MX‑153 is targeted for high‑grade structural adhesive and CFRP composite f

Product Detail

Product Detail PageChemical IdentityMX‑153 is a predispersed core‑shell rubber masterbatch. Nano‑scale polybutadiene‑based core‑shell rubber particles are uniformly pre‑distributed within standard bisphenol‑A (DGEBA) liquid epoxy resin. The CSR particles are already well separated in the carrier epoxy, so compounders do not need high‑energy milling or lengthy mixing steps to achieve homogeneous distribution inside final epoxy formulations. The epoxy carrier shares good compatibility with conventional bisphenol‑A epoxy resins and common amine or anhydride curing agents. It is supplied as a viscous liquid, ready‑to‑use for direct blending into epoxy base resin during formulation work.

Key PerformanceWhen the epoxy system cures, embedded CSR particles serve as energy‑absorbing micro‑sites. Under external mechanical stress, these rubber particles dissipate fracture energy and restrain crack propagation inside the rigid cured epoxy network. MX‑153 raises peel strength and lap‑shear performance of structural adhesives. It greatly improves resistance against thermal‑shock and thermal cycling for CFRP composite parts, reducing micro‑crack formation that frequently occurs under alternating hot‑cold conditions. Importantly, the glass‑transition temperature and heat‑deflection performance of cured epoxy resin will not suffer severe deterioration after MX‑153 incorporation. It maintains stable viscosity behavior during mixing, which supports consistent processing for resin infusion, hand‑lay‑up and adhesive dispensing operations.

ApplicationsThe primary application of MX‑153 is modification for high‑performance epoxy‑based structural adhesives used in bonding metal and composite substrates. It is widely formulated for CFRP carbon‑fiber reinforced prepreg, resin‑infused carbon‑fiber composite components for transportation and aerospace industries. MX‑153 can be adopted in epoxy matrix systems for composite structural parts, where fatigue resistance and thermal‑cycle durability are critical. It is suitable for formulating two‑component structural adhesive for assembly of vehicle components, as well as composite laminates exposed to fluctuating temperature service environments. This toughener fits development projects for high‑reliability industrial and lightweight structural composite products.

Storage & HandlingStore MX‑153 inside sealed original containers in a dry, cool warehouse with recommended storage temperature from 15‑25℃. Avoid prolonged storage under excessively high temperature, which may trigger slow viscosity increase. Prevent direct sunlight exposure. The material will turn more viscous under low‑temperature conditions; gentle warming is allowed before use. After opening the container, seal tightly to avoid moisture contamination. Proper ventilation is required during transferring and formulation operations. Avoid skin and eye direct contact, and wear corresponding personal protective equipment.
