Why do Thermoset resins need toughening?

Many thermoset resins (like epoxies) cure to form hard rigid compositions

Epoxy resins have very low impact resistance

Epoxy resins by themselves have very low elongation characteristics.

Common Methods for Toughening

Vegetable OilsPolyamide or Polysulfide Curing agentsLong chain PolyglycolsReactive Rubber (CTBN)

All of these methods adversely affect the mechanical properties and chemical resistance of the polymer.

Why Core-Shell Rubber?

Over the last fifty years CSR have been successfully used to toughen items ranging from plastic packaging

to automobile parts to building products. Employed primarily in thermoplastic resins (PVC, styrenics,

engineering plastics) global production of CSR today is

estimated in excess of 1 billion pounds.

What is Core-Shell Rubber (CSR)?

The structure of a core-shell rubber particle consists of a cross-linked rubber core encased by a hard “glassy” shell.

Performance can be optimized by tailoring

the structure, chemistry, particle

size and distribution, as well as shell functionality.

Conventional CSR(10 wt%) in Bis A Epoxy

Conventional tougheners

can be difficultand messy todisperse, andoften resultin blendsthat are

inconsistent.

TEM analysis shows complete dispersion of CSR particles via MX while conventional tougheners suffer from agglomeration issues.

DISPERSION is the key to improvement of mechanical

properties!

The technology associated with the

production of Kane Ace™ MX avoids agglomeration

of CSR particles. As aresult fibers

(such as carbon or glass)do not filter out the

CSR particles, allowingthem to toughen even

the resin-rich area between single

filaments.

Cathodic Disbondment Testing

To evaluate cathodic disbondment, the coating is scribed at a point 45 degrees from the edge of the hole. The radius of disbondment area is then determined by inserting a knife point under the coating to "flick" the coating until a definite resistance to this action can be noted.
