Abstract

ABSTRACT

Acrylated hydrophobic coating was prepared from palm oil based urethane acrylate (POBUA) by using the UV-curing technique. The purpose of the study was to investigate wetting properties and the application of this UV-curable palm oil resins for wood coating. Five different sample formulations were prepared that used silica as the roughness agent, PFOA as the modifier and IC-500 as the photoinitiator. Surface contact angle and IR spectroscopy were characterized for each sample. IR spectroscopy confirmed the presence of POBUA resins in all samples. Nine hydrophobic coatings are obtained and the highest water contact angle value acquired is 116.29° which can be considered as a good hydrophobicity value for a wood coating application.

ABSTRAK

Salutan hidrofobik berakrilat telah disediakan daripada akrilat uretana berasaskan minyak sawit (POBUA) dengan menggunakan teknik pematangan UV. Tujuan kajian ini ialah untuk mengkaji sifat kebasahan dan aplikasinya terhadap resin minyak sawit dapat matang UV untuk salutan perkayuan. Lima sampel formulasi telah disediakan menggunakan silika sebagai agen pengasaran, PFOA sebagai bahan penyesuai dan IC-500 sebagai pemulafoto. Sudut sentuh permukaan dan spektroskopi IR dicirikan untuk setiap sampel. Spektroskopi IR mengesahkan kehadiran resin POBUA dalam semua sampel. Sembilan salutan hidrofobik didapati dan nilai sudut sentuh tertinggi yang diperoleh ialah 116.29° yang boleh disimpulkan sebagai nilai hidrofobia yang tinggi bagi aplikasi salutan perkayuan.
