��Exemples d’applications

Examples of applications

Nanostructured PMMA● Very high impact resistance without transparency loss at

high temperature● Very high chemical resistance● Flexible PMMA

Thermoset resins toughening● High impact resistance while keeping Tg and modulus

Structural Adhesives● High performance structural adhesives

Pressure Sensitive Adhesives● New balances of properties for PSA

Nanostrength / Applications

- The French company AEC Polymers has developed an i nnovative range of methacrylic structural adhesives ( SAF® [Strengths Are Flex] ) based on Nanostrength

- Nanostrength leads to high elasticity and superior strength

- Key Properties of SAF adhesives :

- Primer free ; no preparation of the surface to bond ; substrates versatility- High mechanical performance : Strength, elasticity � absorb thermal

expansion and vibration. - Large open time (from 2 min to 2h) followed by a rapid and tunable curing time

PMMA PBA PMMA

• During the curing of the epoxy systems, the soft phase (PABu) phase separates

• The Nanostrength is dispersed at the nanometric scale thanks to the PMMA miscible block until the end of the reaction

• The miscibility of the PMMA block depends on the epoxy-hardener system. A range of Nanostrength with functionalized PMMA blocks (N grades) has been developed in order to keep miscibility in different systems

Nanostrength for Epoxy TougheningNanostrength allows to increase mechanical performance without impairing thermal resistance

Morphology drives the end properties : impact, transparency

Morphology is driven by the nature of blocks

Functionalization of Nanostrength allows to keep transparency of epoxy
