Castadur

Castadur® – the power of regeneration
A self-hardening material of high formability which gains strength without losing its ability to stretch. And even if it loses its properties, from overheating for example, they return. Castadur's softly radiant surface is easy to polish, making it popular for everyday objects such as furniture.

The material's homogeneity and silent power are reminiscent of desert sand dunes, which shaped by the wind are always taking on new shapes while remaining the same.
