Glassflake Epoxy - An excellent System for Offshore Platforms Splash Zone

Due to very severe conditions at offshore, conventional coatings do not work as they require multicoats to acquire high thickness and their curing times are rather high, giving chances for the contamination by severe environment (high RH and salt) in the intermediate layers. Thus, modern coatings which can give larger thickness in just one single coat and cure in a few minutes time are required for critical applications such as splash zone which is marred by continuous dry and wet spell.

Due to very severe conditions at offshore, conventional coatings do not work as they require multicoats to acquire high thickness and their curing times are rather high, giving chances for the contamination by severe environment (high RH and salt) in the intermediate layers. Thus, modern coatings which can give larger thickness in just one single coat and cure in a few minutes time are required for critical applications such as splash zone which is marred by continuous dry and wet spell. Solventless liquid epoxies, modified by glassflakes are excellent alternatives for such systems. Many commercial systems are available in the market. However, understanding on the role of various hardeners, effect of loading and aspect ratio of glassflakes is not very well understood. This paper highlights a systematic development and performance evaluation of glassflake coating work carried out in our laboratory.
