*What is a Salt Spray Test :
Salt spray testing is an accelerated corrosion test used to test the corrosion (rust) resistance of different metals. It does this by exposing components to a constant fog or spray of humid salt water. This harsh environment of salt and heat causes accelerated corrosion to occur.
Why we need a Salt Spray Test :
The results of a material or coating’s resistance to corrosion in a salt spray test can help you determine whether or not a particular metal Fitting is durable and resilient enough for your needs.
condition of experiment:
Salt spray test is s popular test that helps people to assess the surface coating of a products. Hardware are exposed at the temperautre of 37℃ and 5% salt walter for about 24 hours ,48 hours and 72 hours ….depending on the different standards .
Why we need to make Salt Spray Test on metal bag hardwares ?
people like to use nature crocodile skin on their luxury design bags , but real leather are with strong acidity and corrosivity . When the metal hardware ( swivel hooks ,metal d rings , metal chains , metal pullers and zippers , metal labels and so on ) are attaching on the crocodile skin bags , they will be corrosive day by day and plating color will go off . So there is high standard on hardware plating if they are attaching to real leather bags .
We can add the high termperature glaze ( kind of special vanish ) on the metal hardware surface , makes it harder and anti- scratch . Also it works well on the salt spray test even under 15% salt water and 72 hours testing . This helps clients to get the right plating on hardware and keep their luxury bags in a high standard quality for longtime !
