Resin and epoxy resin are two types of materials that can be used to create a mold for casting. The main difference between the two is that resin uses a liquid form, while epoxy resin is solid in its natural state.
Because of this, you don’t need to mix it together before using it as you do with liquid resins. In addition to being more convenient than liquid resins, they also have different applications: Resin works well on smaller objects, while epoxy resin is ideal for making large molds.
Is resin the same thing as epoxy?
No. Resin and epoxy resin are not the same things. Epoxy resin is a type of resin; however, it’s also considered a chemical compound. Resin is the generic term for all polymers like polyester resin, acrylic resin, and polyurethane resin.

Is resin always epoxy?
Resin is the generic term for a liquid that hardens to form a solid. Epoxy resin is often used in building and construction because it has excellent adhesion and works well with metals, plastics, and many other materials. It’s also available in many different viscosities that allow you to fine-tune your project specifications as needed.
Resin can be used as a sealant on wood or other porous surfaces; it can be mixed with pigments for paint, or it can be combined with other chemicals like epoxy resin to make clear coatings or glues.
What is epoxy resin used for?
Epoxy resin is a two-part adhesive that, when mixed together, cures to form a hard and durable substance. Epoxies can be used in many ways to form a variety of different products including art, crafts, and jewelry.
They are also popular for do-it-yourself projects like applying floors or countertops with epoxy resins.
As the name suggests, epoxy resin is used primarily for bonding things together by creating an adhesive film between them.
This can be done using several different methods including coating (for example painting), casting (for example: pouring into molds), or embedding (for example: adhering objects directly into another object).
How long will epoxy resin last?
It all depends on the type of resin you use, as well as how much sun exposure it gets. Epoxy resins are typically composed of two parts: an epoxy resin base and a hardener.
The base is the colored liquid that you mix with hardener to create a cured substance (or take this analogy further and imagine it like mixing two drinks together—the base is like your favorite cocktail). The type of hardener used affects how long-lasting your finished product will be.
For example, if you use an amine hardener (a chemical compound), then your finished product will last longer due to its increased resistance to ultraviolet light damage.
If you’re planning on using epoxy resin outdoors, we recommend choosing one with both UVA resistance and UVB/UVC protection for maximum longevity under direct sunlight exposure!
Which resin is best?
This can be a little confusing, so let’s break it down.
Epoxy resin: Epoxy resins are similar to polyester or polyurethane in that they are used to create strong bonds between materials.
However, epoxy resin has a slightly higher viscosity than polyester or polyurethane and is, therefore, more durable and ideal for tabletops where high-impact conditions may occur. It is also used for laminating because of its ability to resist heat and moisture.
Polyester resin: Polyester resin is ideal for laminating two pieces of wood together because it does not shrink as much as other types of resins when curing (curing refers to the chemical process that occurs when you put your project into the kiln), which allows for fewer imperfections in your finished piece if there were any gaps between them before lamination began. This type of resin also has a low viscosity (low viscosity means it flows easily).
Polyurethane resin: Polyurethanes typically have very low viscosities (meaning they flow easily) but high strengths due to their chemical makeup; this makes them well-suited for casting projects like jewelry because they don’t crack easily as other resins might under pressure from tight molds or casts made out of silicone rubber.
Does epoxy resin break easily?
Epoxy resin is brittle. It’s not good for holding large amounts of weight or supporting weight on thin pieces. If you drop epoxy resin on a hard surface, it will shatter into tiny pieces—like breaking glass.
If you want to make your epoxy more flexible, add some flexible agents (a chemical that helps make materials bendy) like talcum powder or clay to the mix when mixing up your resin glue recipe.
Why is my resin bendy after a week?
As a project sits, the resin cures. The exact amount of time this takes depends on the resin you’re using, but for most resins, it’s about 20-30 minutes. At that point, your piece will be fully cured and ready to use! Resin is cured when it has hardened to the touch — you’ll know with certainty when you can’t indent it with your fingernail anymore.
When resin is fully cured, it’ll have a glossy finish that’s clear enough to see through (if you’re using an opaque white resin).
It also tends to be slightly sticky on its surface; this stickiness wears away over time if left untouched. One final characteristic of cured resin: because it stays flexible even after curing, there may still be given in some parts of your piece when held by hand!
What does resin feel like when dry?
When the resin has cured, it should feel hard and smooth. If it’s brittle, sticky, or bendy, this can be due to a number of reasons:
- Your mixed resin was not mixed properly (too much hardener).
- The catalyst was added too late in the mixing process.
