SigmaShield 420 can be used as a build coat for underwater and boot top systems and offers a high level of resistance to seawater while offering outstanding resistance to abrasion and impact.
SigmaShield 420 can be applied using brush, roller or airless and air spray and is touch dry in 3 hours. After 10 hours you will be able to apply a second coating that leaves you with a high performance epoxy coating with a red brown or grey finish.
SigmaShield 420 is highly suited for use in atmospheric conditions on substrates that require abrasion and impact resistance. SigmaShield 420 can be applied to all surfaces that have been previously coated with Sigmacover 280 or 220.
