Used to improve the functional properties of a substrate on its surface. Conventional coatings adhere to materials by simple mechanical forces will be easily broken causing peeling or delamination. This is not the case with chemical grafting since the attachment of the coating is accomplished by forming a covalent bond between the substrate and the monomers via the substrate activator.
The chemical reaction that takes place provides subsurface penetration in addition to the chemical bond. As a result, much thinner treatment can be obtained while providing longer life and superior performance of the material. Typical treatment methods can be used such as dip, spray, roll. The chemical grafting formulation comes in contact with the surface of the substrate by any of these methods, The chemical grafting reaction occurs instantaneously upon contact with the material. The desired thickness and preferred application method will determine the viscosity of the formulation. Most formulations are water based. The coatings can be air dried, however, heat (oven, IR, UV, etc.) may be used to accelerate the drying time. Most formulations will dry in seconds to minutes.
Painting, anodizing or plating metals are obsolete, utilizing harsh and unsafe chemicals to prevent their corrosion. However, a more reactive metal in the electro-chemical series must be chosen for coating, especially when chipping of the coating is expected. Water and the two metals form an electrochemical cell, and if the coating is less reactive than the coatee, the coating actually promotes corrosion.
