Long-term bottom protection additive

Demonstration experiment


 【Experimental method】
The right 1/2 of the FRP board was coated with commercially available ship's bottom paint only, and the left 1/2 with barnacle guard added ship's bottom paint (brushed 4 times), then immersed in the sea. 

【Experiment Location】 
Tsu City, Mie Prefecture fishing port (Japan)

【Experimental period】
October 14, 2012 - April 15, 2010 (30 months)

【Compound ratio】
Add 3% of Barnacle Guard to the weight of ship's bottom paint. 

【Experimental results】
 As the photo on the left shows, the right side of the FRP plate coated only with ship's bottom paint had dense barnacles adhering to it, while the left side of the FRP plate coated with Barnacle Guard-added ship's bottom paint had almost no marine organisms such as barnacles and mussels even after being immersed in seawater for 30 months.
