Application
Hypax 450-18-70 is usually blended with barium, sodium or calcium sulphonates, oil and/or solvent and for enhanced water displacement 1 or 2% of 2-butoxyethanol (CAS no. 111-76-2). For harder films, high melting point waxes are added along with powdered calcium carbonate or talc. For thixotropic films, crystalline calcium sulphonates are incorporated at typically 10% w/w. These final blends will give good salt fog/humidity protection.
At under 40% solids, there may be some instability in solution.
Performance
A 25 micron dry film of Hypax 450-18-70 will give up to 72 hours’ salt spray resistance (ASTM B117) and good humidity resistance.
Packaging
Hypax 450-18-70 is available in 170Kg net weight steel drums or as required by the customer.
The recommended shelf life of this product is 2 years.
