The term catalyst is much more general than the term hardener, since hardening is only one of endless numbers of processes which can be catalysed. A hardener, therefore, would be a specific type of catalyst.

What is two part epoxy?
The two parts are: epoxy monomer and hardener/catalyst. Upon mixing the hardener/catalyst triggers polymerization of the epoxy monomers and the adhesive sets.
What is 'snow hardener' for ski slopes?
'Snow hardener' does exactly what it says: It hardens snow. Well really, it makes snow more compact. When you are skiing, you dont want soft snow otherwise that will stop your skis by swamping them, and causing lots of friction. What you want is compact snow, so that your skis can go on top of the snow rather than sink in. Snow hardener is just a catalyst for making the snow more compact so that people skiing can ski on the slopes.
How is a catalyst like platinum different from an enzyme?
Catalysts are compounds that change the speed of chemical reactions. An enzyme is a protein and also a catalyst. So an enzyme can be a catalyst, but a catalyst can't be an enzyme.
What is the substance that a catalyst works on?
The substrate on which a catalyst works is called its substrate
What is the catalyst for the reaction between isoprene and hydrogen?
Nickel

How much hardner do you put in auto paint?
Different paints require different amounts of hardener. If there is a label on the paint it should have the ratio on that. One part hardener to the about of paint you use will usually be enough. You can't store the paint after the hardener is in it, it will set up in the can. ----- In actuality a 1:1 mixing ratio of paint to hardener (catalyst) will usually result in brittle massively overcatalyzed paint that will flake and/or chip easily. However as previous stated different paints require different amounts of hardener, alway request a Product Data Sheet (PDS) or Technical Data Sheet (TDS) from the paint manufacturer or retrieve one from their website before mixing.
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
What material is Adhesive in fiber glass made from?
The main material is polyester resin, which is set by a catalyst hardener, so it's basically an epoxy.
Catalyst vs one without catalyst What is different?
what is the purpose of catalyst in textile paint?
What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.
Can Acetone act as a hardener for epoxy resin?
No, acetone is not a hardener for resin

What happens if you put nail hardener on your teeth?
There are toxic chemicals in nail hardener so it should not be put on teeth. Nail hardener is for nails only and will make them stronger.

What is 2K paint?
"2K paint is an epoxy type paint consisting of the base plus a catalyst to start the chemical reaction that the paint needs to cure"This answer above is wrong on 2 major points! It should be removed! A 2K paint is NOT necessarily an epoxy but it could be. In addition, a catalyst is NOT a required component of a 2K paint. Even if the 2K paint is an Epoxy chemistry the curing component (usually called Part B) is called a Hardener or an Activator but is not a catalyst. A catalyst is a separate component and is only a chemical agent that can be added to speed up an existing reaction (a catalyst is not changed or consumed).The Answer:A 2K paint is a 2 Component polymer (resinous) material where the 2 different components must be mixed together for the combined mixture to achieve a cure. When mixed properly in the designed ratio the mixture will achieve the designed cured performance characteristics. It is important to note that off ratio materials may develop hardness but not necessarily the designed long term performance characteristics.The chemistry of the mix can be many different things including epoxy, urethane, polyaspartic, polyurea, or a host of other polymers. The 2 parts are usually referred to as Part A and Part B. Since there are so many manufacturers and chemistries it is difficult to generalize about the names for the Part A or Part B such as Resin, Hardener, Polyol, Iso, Activator, etc. While most epoxy manufacturers call the Part B the Hardener it is not always the case. In addition, it is also prudent to point out that a Catalyst is not the same thing as a Hardener, Activator, or other curing nomenclature. A catalyst is a material that can be added to a mixture to speed up an existing reaction.2K paints should not be confused with 2-Stage paints. A 2-Stage paint is is really 2 different paints that need to be used in conjunction with each other, such as a basecoat that requires a clear coat. This nomenclature (2-Stage) is used heavily in the automotive paint market.
