SOLUBLE (SOFT) ANTIFOULING
General properties:
Protection rather limited, 12-15 months only
Only antifouling type that can be safely applied over soft (bitouminous) primers
The binder oxidizes and is sensitive to sunlight
Sensitive to oil pollution (both mineral and fish oils)
Subject to cold flow

INSOLUBLE (ADVANCED) ANTIFOULING
General properties:
Fouling protection for 18-24 months is possible in normal to severe fouling conditions
The coating can be reactivated by scrubbing
The empty matrix must be sealed off at redocking
The empty matrix may be clogged by pollution, blocking off the toxicants
The empty matrix contributes to increasing roughness development
