Do you know the hardness rating of your epoxy resin?
The hardness rating, or Shore Rating, can help to determine whether a particular epoxy resin is suitable for your project. If you intend to coat countertops, tables and bar tops, you’ll need a hard-curing epoxy resin with a high Shore Rating to do the job properly.
This is exactly what Industrial Clear epoxy resin was designed to do: when prepared according to the label instructions, Industrial Clear cures into a rock hard, durable coating that lasts for years and resists the scratches and damage that can occur in high traffic areas.
How is the hardness of a material measured?
Hardness is measured with a durometer: a device featuring a pointed metal indentor with spring resistance. A durometer works by pressing the spring-loaded steel tip into a surface to measure how resistant the material is, based on the depth of the indentation and the force required to create it.
What is the Shore Hardness Scale?
The Shore Hardness Scale, created by Albert Shore in 1920, quantifies hardness from 0 (the softest and most flexible) to 100 (the hardest and most brittle) for various materials. Resins are measured on the Shore D scale for rigid materials (as opposed to Shore 00, Shore A, Shore B, etc, which are used for other types of materials).
Chart Of Shore Ratings
Below is a chart outlining the Shore ratings of some commonly found materials.
Shore 00 is for very soft gel materials.
Marshmallows and gummy candies: 10
Chewing gum: 20
Gel shoe insert: 30
Silicone mold: 50
Shore A measures the hardness of flexible rubber materials.
Rubber band: 25
Inner tube: 40
Pink eraser: 55
Car tire tread: 70
Skateboard wheel: 98
Golf ball: 50
Wood ruler: 70
Hard hat: 75
Industrial Clear: 83

Is epoxy harder than glass?
Glass is typically harder than epoxy resin but is considerably more fragile. In contrast, epoxy resin provides the same glossy and crystal-clear appearance as glass but with greater durability. Resin's natural flexibility means it can better withstand impact and is more likely to bend than break, unlike glass which can shatter. Epoxy resin is more susceptible to dullness and scratches, however surface damage can be fixed by applying a fresh layer of resin on top.
Is epoxy as strong as steel?
While not as strong as steel, epoxy resin does offer a number of notable advantages. Steel is susceptible to erosion, with deep scratches causing rust and corrosion issues even on coated steel.
In contrast, epoxy resin is resistant to rust and corrosion and impervious to moisture, chemicals, and bacteria. Furthermore, its strength makes it a viable alternative to welding and soldering. A potential drawback, however, is its tendency to become brittle in extremely cold temperatures.
Nonetheless, epoxy composites are quickly emerging as the strongest materials available, surpassing conventional options like steel, and are being increasingly utilized for constructing and reinforcing structures.
Is epoxy stronger than glue?
Glue has the advantage of being cheaper and can be applied directly from the bottle without the need for mixing. However, if you have leftover resin, you can easily re-purpose it to fix a number of broken objects around the house, to cover rust on metal, and to seal and waterproof various items.
Is epoxy harder than concrete?
Epoxy resin’s outstanding mechanical properties make it stronger than concrete. Once cured, it becomes almost unbreakable, significantly reducing the chances of cracks or damage from impact or abrasion. Furthermore, cured epoxy requires minimal maintenance and will endure heavy wear and tear for decades with exceptional resistance to chemicals, moisture and bacteria.
One distinct advantage of concrete is that it’s more fire-resistant than epoxy resin. Nevertheless, concrete is more prone to cracking and has poor resistance to chemicals, moisture and mold.
