FROM WASTE TO HIGH VALUE PRODUCT: ECO-HYBRID COATING (EHC) AS SUSTAINABLE MATERIAL


By Nano and Advanced Materials Institute (NAMI)


Woodplastic composite (WPC) product is one of the common materials extensively used in construction industry, from plain road pavement to beautiful interior decoration. Their component’s natural behaved very differently. Wood is hydrophilic that would easily absorb moisture or water from the environment and swell to change in shapeon the other hand, plastic is hydrophobic that repel moisture or water.


The water absorption properties by wood causes poor weather resistance of WPC product that it would deform easily under atmospheric changes. In addition, due to the stubborn and restricted process of existing WPC production limits the product customization, especially the shape of final product, which limits the application flexibility of WPC.


Realizing the limitations of existing WPC products, a Hong Kong company who has experience on applying foreign WPC products approached Nano and Advanced Materials Institute Limited (NAMI) with an Innovation and Technology Fund of HKSAR- supported R&D project to develop a novel Eco-Hybrid Coating (EHC).

THE COATING SOLUTION DEVELOPMENT EHC is a solution form coating to be applied on metal surface to provide WPC-like appearance. It is made from recycled wood and plastic wastes. By the NAMI’s innovative formulation technology, the hydrophilicity of recycled wood is reduced and the affinity between plastic and wood are increased, enhancing their compatibility to prevent deformation by weather change.
