Many projects, from coasters to river tables, from boats to bar tops, require an epoxy resin that will not only cure rock hard, but will stay hard for the long term without bending.
If a resin is too hard, however, it can get brittle and become prone to cracking. In marine applications, for example, an epoxy resin that is too hard may snap and crack as the boat naturally flexes and warps in water. Many super hard resins on the market will fracture if flexed or compressed.

When developing Industrial Clear, our goal was to strike the perfect balance between hardness and flexibility. We did a ton of testing and developed an epoxy resin in the perfect sweet spot: it has a durable, rigid finish and high Shore hardness, but we left just enough flexibility to prevent cracking. You can be confident that the movement of your substrate will not fracture Industrial Clear.
Will Industrial Clear epoxy resin dent?
If you push a fingernail into cured Industrial Clear resin, it may dent, but it will return to its original shape in just a few minutes. This property is called elasticity, and you want your resin to have a little bit of this to prevent cracking.

How long does it take for Industrial Clear to cure?
Industrial Clear will be solid and dry to the touch at the 24 hour mark, but a full cure requires 3-5 days for it to become rigid and keep its shape. Often, resin that seems "bendy" simply hasn't finished curing yet and just needs a little more time.
Can I shape and mold Industrial Clear?
Yes, Industrial Clear can be shaped and molded while it's curing. Allow the mixed resin to sit for approximately 5-6 hours until it is dry to the touch, but still pliable. At this point, you can bend, mold and shape it however you want. Industrial Clear will hold the shape as it cures to a rock hard solid over the next few days.
How strong is Industrial Clear epoxy resin?
Industrial Clear is a high-strength epoxy that will not bend and has enough elasticity to prevent it from cracking. It has undergone numerous tests to assess its mechanical strength properties including tensile, compression, bend, peel, tear, shear, friction, torsion, and elasticity and puncture tests.
These tests involve a machine called an Instron which uses force in various ways to measure how strong the resin is. One of the most fundamental properties tested is tensile strength: this refers to the maximum stress that the cured resin can withstand before it breaks. By doing this, the tests determine how strong the resin is. Industrial Clear has a tensile strength of 7100 psi (ASTM D638).
No matter what your project, we've got you covered! Industrial Clear epoxy resin cures hard with a bit of built-in flexibility to prevent cracking, without sacrificing strength.
