Wettability of adhesive on oil palm lumber surface / Mohamad Azlie Abd Rahim

This thesis discusses about the wettability of adhesive and on the oil
palm lumber surface. The experiment was about the ability of three
types of adhesive such as Urea Formaldehyde (UF), Phenol
Formaldehyde (PF), and Polyvinyl Acetate (PVAc) to wet the surface of
oil palm lumber. The testing method is by using different time at
different sample of oil palm lumber such as in one minute and compare
with five minutes. In addition, the contact angle on the surface of
substrates is important to determine the strong bonding and
attachment between two surfaces of bonding material. By using
different adhesive we will know the ability difference based on the
adhesive on the surface of oil palm lumber. When the result shows the
best performance on the oil palm lumber it will be selected as the
successful wetting angle and suitable for used on the oil palm lumber
surface to assemble good product. The results shows that different
types of adhesive and time give significant effect on the wettability on
oil palm lumber surface.
