a substrate that is not porous. IE has no pores. But more importantly it is impervious to water or air. In a material this would mean that an adhesive would need to either melt/weld or create a bond between it and the substrate. A water based glue for example would want to penetrate the surface of a substrate to create a surface it can bond to. A non-porous substrate would not allow this and so the bond, if an, would be weak.
means a smooth, unpainted solid surface that limits penetration of liquid containing PCBs beyond the immediate surface.
not having vessels that appear as pores.
Yes it is
It is.
Correct, vinyl is non-porous.
"Yes, they do stain clothing. They are meant to be erased from nonporous surfaces, and clothing is very porous. If it can be removed, it is with a pretreatment and washing in hot water." Note: Heat can set stains! Check with the manufacturer or check the recommendations for your clothing item.
Cameo Surface: The surface that you can see. Intaglio Surface: The surface that you cannot see. Example, there is a dish on the table. Upper side of the dish is cameo surface and the bottom side of the dish is intaglio surface.
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
the lack of a surface.
Yes, we generally consider stainless steel to be a nonporous surface.
Surface tension of water draws it into a larger drop. It will do that on any nonporous surface- metal, glass, smooth plastic, etc.
Leather is porous unless the surface has been waterproofed. Dubbin is one product that is frequently used to waterproof walker's boots.
Drywall is VERY porous .
The easiest way to clean a nonporous surface of black mold is to scrub it off with a solution of 1 cup of borax to 1 gallon of water.
Correct, vinyl is non-porous.
No, Stainless steel is not porous. Steel how ever is.
Silk is porous -- it absorbs liquids.
No, luan is a plywood and wood is naturally porous.
Polycarbonate is a material similar to acrylic. It is a thinner and lighter alternative to plastic. Polycarbonate is also impact resistant and because it is a tougher material, it tends to be more scratch resistant as well. Polycarbonate cutting boards are good, because of the impact resistance. It's also good because it is nonporous, and cleans easier. Because of the nonporous surface, it does not harbor bacteria. Most polycarb cutting boards are treated with an antibacterial agent.

I was curious as to the exact definition of these porous and nonporous because every time I picked up a cleaning supply it would always mention something about whether the product could be used on one or how to treat the area differently depending on whether it was one versus the other. Interestingly enough, a simple google search proved to be much more mystifying and arduous than I would have ever imagine because there was no straightforward answer and all the links characterizing porous v nonporous surfaces were mostly from scientific journals or .edu sites. But to be as concise and brief as possible, from what I gathered, there are a wide array of factors and characteristics to consider for any given material to determine porosity but the main gist is: Porous surfaces are anything that can be penetrated into beyond its outer surface due to either small or narrow spaces which allows absorption, low density, etc. It is porous, or not impermiable. Water, or any other liquid can pass through, for example. Nonporous surfaces on the other hand tend to be thick, dense, and solid do that nothing can permeate it beyond its outer-most surface. Examples of porous and nonporous materials: Porous: fabrics, unvarnished (unfinished) woods, cotton, carpeting, and unsealed tiles (depends on tile type but most need laminate) Nonporous: solid plastics, metal objects (stainless steel, aluminum, chrome, etc), glass of all forms, ceramic surfaces like dishes etc, varnished wood, laminate counters, granite, and vinyl
