Production Description
Epoxy resin E51 is a bisphenol A liquid epoxy resin, which belongs to basic epoxy resin and is a low toxic, colorless or yellowish viscous liquid. It is mainly used for bonding, casting, sealing, impregnation, lamination and other fields. It can also be used as raw material for epoxy resin processing. It accounts for a large proportion in the application of coatings. The solvent-free or less solvent-free coatings prepared by epoxy resin have strong corrosion resistance, and have little environmental sludge during construction. It coatings are mainly used as anti-corrosion paint, metal primer and insulating paint. Its commonness:
1. Good chemical resistance, especially alkali resistance.
2. The paint film has strong adhesion, especially to metal.
3. It has good heat resistance and electrical insulation.
4. The paint film has good color retention.

Technical Data for E51
Property and Characteristic
High mechanical properties. Epoxy resin E51 has strong cohesion and dense molecular structure, so its mechanical properties are higher than those of general thermosetting resins such as phenolic resin and unsaturated polyester.
Strong adhesion. The curing system of epoxy resin contains epoxy group, hydroxyl group, ether bond, amine bond, ester bond and other polar groups with great activity, which endows the epoxy cured material with excellent adhesion to polar substrates such as metal, ceramics, glass, concrete and wood.
Good processability: epoxy resin basically does not produce low molecular volatiles when curing, so it can be molded under low pressure or contact pressure. Epoxy resin E44 can be used with various curing agents to manufacture solvent-free, high solid, powder coatings, water-based coatings and other environment-friendly coatings.
Excellent electrical insulation: Epoxy resin is one of the best varieties of thermosetting resin with medium electrical properties.
Good stability and chemical resistance. The epoxy resin without impurities such as alkali and salt is not easy to deteriorate. As long as it is properly stored (sealed, free from moisture and high temperature), the storage period is 1 year. It can still be used if it passes the inspection after expiration. The epoxy curing compound has excellent chemical stability. Its corrosion resistance to alkali, acid, salt and other media is better than that of unsaturated polyester resin, phenolic resin and other thermosetting resins. Therefore, epoxy resin is widely used as anti-corrosion primer. Because the cured epoxy resin has a three-dimensional network structure and is resistant to oil impregnation, it is widely used in the inner wall lining of oil tanks, oil tankers and aircraft.
Storage and Shipping
When storing epoxy resin, please keep away from direct sunlight, heat source, ignition point and waterproof. Dangerous goods shall be stored according to regulations. If they are not used up after opening, they shall be sealed for storage. The shelf life of epoxy resin is generally 1 years, and it can still be used after passing the retest. Under relative conditions, such as storage at freezing temperature, some epoxy resins may crystallize, which is only a physical change and does not change their chemical properties. In case of crystallization, the resin can be heated to 70-80 ° C and restored to its original state by stirring.
Usage
Epoxy resin is rarely used alone. Generally, auxiliary materials such as curing agent filler are used. Tertiary amine compounds are used as curing agents, which are usually 5 to 15% of the resin amount. Acid anhydride is used as curing agent, which is 0.1 to 3% of the resin amount. Polybasic adhesive is used as curing benefit. Epoxy resin is cut to 1:1 mol cal. 703 is used as curing agent, which can be used according to 1.0.4
- Q: i went on the web site of microlon an it say this stuff last a life time no need to keep adding only once an your engine is protected for life is this stuff for real an it cost 99.99 for a 32 once can witch treat an 4,6,8 cylinder engine
- companies like Mobil ,chevron etc spend millions of dollars a year doing research on additives to make our engines last longer, dont you think if theres something better they would add it to the oil? there have beenperformance additives since theres been cars , I am not going to disparage Lucas but most additives are just snake oil if you want to take care of your engine go out and buy full synthetic oil on your next oil change , this will save on engine wear, and fuel
- Q: I am actually trying to dye my hair purple. I just bought Chi Purple Color Additive and Chi Dark Ash Ash Blonde dye with 10 Volume Chi Color Generator. I currently have long ombre hair, light/medium brown near the roots and blonde at the tips. I prefer not to make my hair darker, and I prefer not to bleach it. Does anyone know how it would turn out if I mixed the Dark Ash Ash Blonde and the purple additive?
- I dont realize what to say but, long curly hair is cute but you keep moving your hair up so you can easily see, short hair is cool and also you dont have to flick your current hair up at all
- Q: What ingredients are added to the bread
- A leavening agent is an additive that can form a bulky and porous structure in the process of bread processing, and has a soft, palatable property, also known as a bulking agent. At present, commonly used in the production of dried yeast is a dry yeast, usually granular products; In addition, there are baking soda, powder, baking powder and other chemical leavening agent.
- Q: explain how the additive color model and the subtractive color model in commercial printing are related and why the standard painter subtractive primaries are not used. THANKS!
- Primary colors are :Blue, Red, Yellow. I don't know why someone would say green, because the point is that mixing two of the 3 colors make another, for example blue and yellow makes green.
- Q: need help please!! thank you gt;.lt;
- Additive Inverse Property
- Q: I don't know if I have a limited slip differential or not, so I was hoping I could put in the additive in either case?2003 Ford Explorer XLT V8 4X4.
- NO! you dont choose a posi with a 4 barrel carb. That became a stupid situation to declare. First, a 4 barrel doesnt advance the horse skill enuf to warrant that. in case you upload a cam, headers, hi-compression pistons and a few different issues, possibly. I actual have a hotrod with a souped up 350 and that i've got an open 9" ford. Its been on the line for six years and its positive. in case you opt for to floor it for all time, you would be able to remorseful correct to the open rear end yet once you develop up without postpone without breaking the tires unfastened, youre positive
- Q: I know what an additive inverse is,(5,-5 2,-2) but what I dont get is why its called the additive inverse. If you take a number like -5 then shouldnt the additive inverse be correctly called 10 to get 5? because its the add-itive inverse(opposite).
- The inverse of an operation is chosen to get the identity of that operation. The identity is the one that when performed on a number (or whatever) doesn't change it. For addition (and subtract which is just adding negatives) that identity is 0. Anything ± 0 is anything. So if you choose something like 5 then you want to know what the solution to 5 + n = 0 is. Inversion of operations (and functions) in math isn't the same thing as the word inverse itself. To invert something is to literally turn it over. In math the inverse is the thing that undoes. For mathematics when something is undone the result is the identity. For multiplication the identity is 1 so the inverse in multiplication is the reciprocal because it satisfies xn = 1 n = 1/x x(1/x) = 1 For functions the identity is x because if you have a function y = f(x) then if you plug in x you'll get back y. So the inverse function f??(x) will give back x when applied so that f(f??(x)) = x Since composition is the operation here the other way must also be satisfied to be a valid inverse, that is f??(f(x)) = x This idea also goes for matrices and other constructions in math. I hope this helped or was at least mildly interesting. Good luck!
- Q: Consider ? and ? as additive groups, the latter being a subgroup of the former. Prove ?/? ? (s)^1 { a+bi ∈ ? a? + b? 1} (Hint use the morphism f: ?→ s^1 x (maps to) e^ 2πix
- Let's first consider what the two groups look like. The group R/Z is an additive group, with cosets looking like r+Z, where r is in [0,1). Addition is like addition in the reals, modulo 1. You can and probably should prove that statement, by showing that if a+bc mod 1 then (a+Z) + (b+Z) (c+Z) in R/Z, and that this doesn't depend on the choice of a, b or z, so that each can be taken to be in [0,1). That's just the usual expression of numbers mod n as equivalence classes with the standard term used to express the classes as being in [0, n). The group s^1 (I'll just call it S) is a multiplicative group of the complex number with norm 1. Note that f(r) e^ir (with r a real number) is periodic with period 2π. So they expression e^2πix is just a minor change in variable making h(x) e^2πix periodic with period 1. We need to prove that h maps cosets of R/Z map to a unique point in S, and preserves the group operations. It should be pretty clear at this point that this is the case, but let's go through the motions with a more formal proof. It should be clear that the function h(x) e^2πix (which we wish to prove is an isomorphism) is bijective and preserves the group operations: 1. If x y+n (mod 1) so that x and y are in the same coset of R/Z, then h(x) e^2πix e^2πi(y+n) e^2πiy X e^2πin, e^2πiy since e^2πin cos(2πn) + isin(2πn) 1. By the way, this also illustrates that the kernel of H is 0+Z. The integers in R map to the multiplicative identity in S. So if x y in R/Z, h(x) h(y), showing that h is well-defined. You can reverse the math to show that it's 1-1. And if point s in S e^2πit, then h(t) s, so H is onto. 2. Since h(a) + h(b) e^2πia + e^2πib e^2πi(a+b) h(a+b), h preserves the group operations. Therefore h is an isomorphism of R/Z to S.
- Q: If it isn‘t then what property is it?
- It's an example of the additive inverse. -12 is the additive inverse of 0. 0 is the additive identity element, just as 1 is the multiplicative identity element. The inverse is the number (for the specific operation) that yields the identity element.
- Q: That‘s a lot of gas to dispose of. I have no idea what to do with it.
- Instead of worrying about where to dispose of the gas, you will be better advised to find out why the car will not run, as it's very unlikely the additive is the cause. There is another problem here other than contaminated gasoline, and it will no tgo away by just draining the tank. Fuel pump, fuel filter, plugged fuel injectors, a sudden ignition problem, many things could have happened near the same time as the additive being installed.
