02Why It Matters
Why Defend 220™
Traditional two-coat epoxy tank lining systems require extended application time, multiple coats, and long cure cycles before return to service.
Defend 220 changes that equation. As a one-coat hybrid high solids Novolac tank lining, it is engineered to deliver efficient performance with significantly reduced application time. With return to service in as little as 4 days, Defend 220 reduces vessel or tank downtime while maintaining the corrosion protection asset operators require.
