The effect of matrix compound on the behaviour of a silane-zeolite composite coatings on 6061 aluminium alloy was evaluated. It was observed that silane molecules containing long aliphatic chain or reduced hydroxyl groups influenced wettability and mechanical performances of coatings. Silane compounds with long alkyl chain or bi-hydroxyl groups allowed to obtain more adherent and hydrophobic coatings. Furthermore, composite coatings characterised by multi-component silanes mixture (short and long chain molecules) evidenced affordable impact resistance compared to coating made of silanes with aliphatic chain functional groups.

Abstract
The effect of matrix compound on the behaviour of a silane-zeolite composite coatings on 6061 aluminium alloy was evaluated. It was observed that silane molecules containing long aliphatic chain or reduced hydroxyl groups influenced wettability and mechanical performances of coatings. Silane compounds with long alkyl chain or bi-hydroxyl groups allowed to obtain more adherent and hydrophobic coatings. Furthermore, composite coatings characterised by multi-component silanes mixture (short and long chain molecules) evidenced affordable impact resistance compared to coating made of silanes with aliphatic chain functional groups.File in questo prodotto:
