Abstract

Polyurethanes are an important component in major appliances that consumers use every day. The objective of the present work is to perform a scratch test to measure the abrasion wear resistance of polyurethane coating. Scratch test carried out to investigate the friction coefficient and abrasive wear resistance respectively.
 
The experiments were carried out by heated test specimens to 80, 90, 100 and 110 °C for 5 and 10 minutes then cooled in air and furnace. Wear resistance can be obtained by measuring the wear scar width. The friction force measure from load cell and the normal load measure by dead weight. The applied load values were 2, 4, 6, 8 and 10 N.
 
Test results show that, the minimum values of friction coefficient observed for polyurethane coating heated to 90 °C for 5 minutes cooled in air. The maximum values of friction coefficient showed by specimens which heated to 90 °C for 5 minutes and cooled in furnace. Wear of polyurethane coatings decreased as the cooling rate decreased. The heat treatment process of polyurethane coating showed significant effect on the wear resistance. Polyurethane coating heat treated to 100 °C for 5 minutes and cooled in furnace showed the higher wear resistance.
