The almost indestructible coating of Ocean Defender is made of Polyurea,one Black Technology Material ( Polyurea is a branch of polyurethane ). This Black Technology Material is independently developed by us which have very important properties like:extremely strong, stretchable, flexible, anti-deformation, anti-corrosion,UV resistance etc.

The polyurea coating is a direct protective measure for foam core, so the quality and performance of polyurea coating directly determine the strength and service life of foam fender, which is a pitfall point that users need to pay special attention to.

You can imagine the result of a watermelon falling from height,but if the watermelon is sprayed with our black technology material and falls from the height of 100 meters, can you still imagine the result?
