What it is: The most innovative water resistant coatings are based on nanotechnology, and do not just coat a substrate but actually bond with it, forming a layer that is no longer separate. Nanoscale coatings for innovative water protection Watertight consumer products use water resistant coating for electronics 2.
Uses: Steel structures and products, in tougher environments as pretreatment with a further topcoat. Properties: Corrosion resistance, limited water resistance. However, this is often not sufficient, so to conform to tougher waterproofing requirements it is topped with a resin or fluoropolymer coating. These processes also provide water resistance, to a certain extent, by covering the original metal substrate.
What it is:The treatment of a metal surface with another metal in processes like galvanisation and anodisation is seen as an effective corrosion protection method in certain environments. Surface coating technologies for watertight pre-treatment Here are four of the most common water resistant coating solutions: 1. On the other hand, a waterproof wall paint never is 100% watertight, due to the fact that it needs to remain breathable. However, not every water resistant coating suits all situations like with all coating projects, you need to take into account the intended substrate, use, and environment of the coating, as well as that the required degree of water resistance. For example, a water resistant coating for fabric needs to be invisible, water resistant coating for electronics must be applicable in thin films, and steel requires an impermeable barrier to protect from corrosion. Waterproofing products are as various as waterproofing projects. When choosing a coating, you should always check the datasheets and instructions.Ĥ coatings that function as water resistant treatment But these are descriptions that can apply to more than just coating. ‘Water resistant’ is also the general term for water protective coatings.ĭespite the difference between waterproof and water resistant, consumer products may still be labeled waterproof when they are only resistant, and vice versa. Able to resist water penetration to a certain extent, but not entirely – in most cases a ‘water resistant’ product cannot be completely submerged without problems. Water resistant: Usually the lowest degree of water resistance.Often refers to nano- or fluoropolymer coatings which literally repel water. Water repellent: Higher resistance than ‘water resistant’, yet also not completely impermeable to water.Waterproof: An almost 100% watertight solution, these coating systems are absolutely impermeable to water.Water resistant coatings can be classified by their degree of water resistance as follows:
Though the terms ‘water resistant’, ‘water repellent’ and ‘waterproof’ are often used interchangeably, they actually describe different degrees of water resistance. The 3 definitions of water resistant coating In this article we will describe the different water resistant coating systems, outline the options for different industrial and architectural applications, and discuss the most common issues linked to water resistant treatment of surfaces. It is also required from industrial machinery and architectural structures. A water resistant coating is the most common solution for improving or creating water resistance in industrial and architectural projects. Water resistant coatings form a barrier between the substrate and its environment depending on the water resistance treatment, the barrier can be impermeable to both water and water vapour. Water resistance is a characteristic expected of many consumer goods, from electronics to shoes and fabrics. Water resistant coating – watertight solution
