Protite Resin Catalyst Hardener is used to cure Protite Resins and Protite Clear Casting and Embedding Resin. Add to fibreglass or clear casting and embedding resin to start curing process.
Do you need catalyst for resin?
Epoxy resins come in two seperate componants. No catalysts are needed. The two componants when mixed will react with each other to crosslink and polymerise into a solid plastic.
What is catalyst in epoxy resin?
In epoxy, curing occurs with the help of a catalyst, which is chemical additive that increases the rate of a chemical reaction. This results in an exothermic reaction that creates a cross-linkage in the polymer. This cross-linkage is responsible for the rigidity and strength of epoxy materials.
How much catalyst do you put in resin?
The ratio range for catalyst to resin is 1 to 2 percent hardener to the total volume of resin to be used. For example, four drops of hardener will be 1 percent of 1 ounce of resin. Adding more of less of the catalyst agent will speed up or slow down the curing time for the resin.
Is catalyst the same as hardener?
As nouns the difference between catalyst and hardener is that catalyst is (chemistry) a substance that increases the rate of a chemical reaction without being consumed in the process while hardener is one who, or that which, hardens.
Why is resin so expensive?
Epoxy resins are more expensive to produce than other types of resins. This is because the raw materials required for manufacture cost a lot more than other low-end resins and the process of the production is complicated with a low tolerance for errors.
What can I use as a catalyst for resin?
MEKP (Methyl Ethyl Ketone Peroxide) is the catalyst added to polyester resins and vinyl ester resins. As the catalyst mixes with the resin, a chemical reaction occurs, creating heat which cures (hardens) the resin. Use approximately 1/2 oz per quart of resin.
Whats the difference between epoxy and resin?
The most noticeable difference between these two compounds is their intended use. The Epoxy Coating Resin is intended for coating surface applications, while the Casting Resin is used mainly for jewelry, molds or figurines.
Is epoxy hardener a catalyst?
However, simply adding a hardener to an epoxy resin may not cause the epoxy mixture to cure quickly enough. If this is the case a different hardener may be required. Also, hardeners with certain additives can be used. These hardener additives serve as catalysts that speed up the curing process.
What is the cost of epoxy resin?

What happens if you put too much hardener in resin?
Measure ArtResin in precisely equal amounts by volume: Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.
How much hardener do I mix with resin?
Mix the resin VOLUME – To achieve the correct 2:1 mix ratio by volume, simply measure out 2-parts resin to 1 part hardener before mixing the components.
What is the ratio for resin?
Typically, this is 1 : 1 or 2 : 1 between resin and hardener, but there are also much more complicated ones such as 100 : 45. You can usually find the details on the packaging or containers. The mixing ratio has to be very precise, otherwise the epoxy resin will not harden or it will not work optimally.
What is the difference between resin and hardener?
As nouns the difference between resin and hardener is that resin is a viscous hydrocarbon secretion of many plants, particularly coniferous trees while hardener is one who, or that which, hardens.
What’s the difference between a catalyst and accelerator?
The catalyst does not take part in the chemical reaction but simply activates the process. An accelerator is added to the catalysed resin to enable the reaction to proceed at workshop temperature and/or at a greater rate. It is a non-reversible chemical reaction.
What’s the difference between activator and hardener?
From a general standpoint activators and hardeners do the same thing; initiate cure of 2K products. However, you must use only the activator each product calls for on the tech sheet and not interchange hardeners/activators from different brands or products. 2 of 2 found this helpful.
Does resin break easily?
It is water-resistant, not prone to cracking, peeling, or other damage, and it is a highly durable material that will not break easily or shrink once hardened.
Are resins toxic?
What safety precautions should I take? Craft Resin is considered a non-hazardous material and is non-toxic when used as directed, however there are some common sense safety precautions that every user should follow: 1 – Wear gloves.
Is resin a strong material?
Well, it’s true that most standard resins are relatively brittle compared to other 3D printing materials and aren’t recommended for stressed parts or outdoor use, although there are tough and durable resins on the market specifically formulated for stronger applications, and they can be really strong.
Why catalyst is used in resin?
Many reactions in the resins and coatings industry require a catalyst. If the resulting products are at a lower energy level, the reaction is called exothermic. Nice examples are isocyanate/hydroxyl and acid/epoxy. If the products are at a higher energy level than the surfactants the reaction is called endothermic.
Which is better epoxy or polyester resin?
Epoxy is more resistant to wearing, cracking and peeling, and corrosion or damage from chemical or environmental degradation. Polyester is more fragile and useful for temporary fixes, or low-stress use. Epoxy is generally more expensive than resin, due to its strength and formulation requirements.
Can you mix resin in paper cups?
50 Graduated Paper Cups Perfect for mixing small batches resin, paint, stain, epoxy from 1 to 3 ounces. Cups are are wax coated. They are sturdy and smooth on the inside to help with complete mixing. They are flexible enough to make pouring easy.
