“Silco” products have evolved over many years. Product lines have been rationalised
Surface chemistry has improved - mainly as a result of thicker coatings and proprietary added deactivation where appropriate
- application specific Silco products for optimum performance

Silco - High temperature Vapor Deposition process of depositing fused silicaon to SS

Silcosteel and Sulfinert Tubing ( some other products ) are still available from Chromtech stock
at discounted prices ( 20% off List Prices ) until stock is depleted
