In industrial cleaning and metal treatment, effective corrosion protection is vital to maintaining efficiency, extending equipment life, and ensuring safety. HARKE UK & Ireland is pleased to introduce DeCORE™ TOS from Verdant Specialty Solutions, a powerful corrosion inhibitor designed specifically to enhance your industrial cleaning formulations.
DeCORE™ TOS is an innovative blend of dialkyl thiourea and surfactants, engineered for superior performance in harsh acidic environments.
This versatile ingredient significantly reduces acid attack on metal surfaces, and is ideal for applications such as acid pickling, surface preparation prior to painting, plant cleaning, and oil well acidising. It is also non-foaming.
Key Benefits of DeCORE™ TOS
- Highly effective corrosion inhibition, even in aggressive acid solutions
- Non-foaming formulation, ideal for a variety of cleaning applications
- Easy to handle, pale yellow homogeneous liquid
- Excellent solubility in acidic solutions
- Prolongs the lifespan of metal equipment and surfaces
Testing Data
DeCORE™ TOS has been thoroughly tested under aggressive acidic conditions to confirm its corrosion inhibition performance across multiple metal types.
Testing in 10% and 20% sulfuric acid showed that steel coupons treated with 0.25% active DeCORE™ TOS experienced minimal corrosion, even after prolonged exposure of 45 days:
Short-term weight loss studies further confirmed effective protection of mild steel, with DeCORE™ TOS significantly reducing metal loss in both sulfuric acid concentrations.
Additional testing on mild aluminium over 7 days demonstrated strong corrosion inhibition in both sulfuric acid (10-20%) and highly aggressive hydrochloric acid (5-10%) environments:
