Q:What is the reason that the performance of self - curing resin is lower than that of heat - curing resin?: Weather resistanceWeather resistance is one of the main characteristics of silicone resin and is widely used as base material for weather resistant coatings. The simplest way to test the weather resistance of coatings is to expose the test panels coated with silicone to the outside, and to observe the changes in gloss or color of the coating, as well as cracking. But because sunlight exposure, the specimens received in outdoor temperature changes, rain, snow, wind and frost attack, floating in the air and dust pollution of various chemical substances are not the same, so it is difficult to have strict standards. Making comparison and analysis difficult. In addition, the results of the cycle is long (in years), so the use of this method has been less, and now use accelerated aging test machine, to obtain weather resistance data. Under the condition of accelerated test, the coating gloss 60%, alkyd resin coating is 250h, containing 30% (mass fraction) silicone alkyd resin coating is 750H, containing 50% (mass fraction) silicone alkyd resin coating is 2000h, and the silicone coating after 3000h, the gloss retention is still higher than 80%. Among the many factors that cause coating aging, sunlight, especially ultraviolet radiation, is the major cause of low gloss and powder surface. It is known that the light spectrum in the wavelength spectrum of the solar spectrum on the earth's surface is very sensitive, which is the root cause of the poor weather resistance of organic resins. Known, methyl siloxane hardly absorb the ultraviolet light, containing PhSiO1.5 or Ph2SiO links are only following the absorption of 280nm silicone (including a small amount of ultraviolet light), the sun has little effect on the silicon resin, which is the main reason of silicon resin coating with excellent weatherability.

Q:I've baked a zucchini bread recipe I got off an internet recipe site. I follow the recipe instructions to the T. But I find that even after baking for the prescribed time the bread doesn't bake completely thru to the center and then sags and falls in on itself. I'm wondering if the fact that I'm using a disposable aluminum bread loaf pan has something to do with this as this occurs even to my wife when she makes bread in a regular oven. Is it because of the type of bread pan? Does the thickness of the pan allow the outside to bake sooner than the interior?: Varathane ) ADDED LATER just noticed that you said you were using a doming resin. That could mean that you're not really using true resin. but a dimensional white glue like Diamond Glaze, etc. Those are already permanent white glues, but they will dome more than regular white glues while drying. They aren't very tough though so a coat of polyurethane on top will make them less scratchable and susceptible to later cloudiness from humidity, etc. HTH

Q:I have been thinkingThe max you can go over a speed bump with comfort towards you and your car is 20mph.We all know that going slower than the speed limit is more dangerous than going the equal amount of speed higher. So why are there speed bumps in 30mph zones when they are forcing you to do 20mph. I personally think they should ban all speed bumps and just put speed cameras because the constant accelerating and decelerating is causing your car to emit more emissions.What do you think?: Chances are if it's a newer model It has a spark igniter.No pilot.And no If it does not light it doesn't just keep pumping gaslol It should be pretty easy to diagnose the problem bc you can hear the burner ignite on a gas dryer.So the first thing is just stand there and listen when you turn it on. If it doesn't light then obviously you have a problem in the ignition system somewhere.Not really a DIY thing. If it ignites for a minute or two and goes out.Then I would check the vent hose to see if it's clogged somehow.Bc if it can't vent exhaust This will cause it to go out too.Also check for a buildup of lint.Not just in the lint trap but inside around the drum too.

Q:Ok here is the situation i got a door nob from a dollar store it is connected together one side is a key lock part and the other side is a push button lock. Now the hard part how DO I TAKE IT APART? OR HOW DO I INSTALL IT. Oh yeah it has no common name it says Wonderful HIGH DOORLOCK doorlocks: Resin can be mixed with a variety of powders: bronze, marble, etc and can take on the appearance of real bronze or marble sculpture. You pretty much get what you pay for. For $5 you will get cheap crap for 2 - 3 hundred you approach a piece of real art.

Q:How high is the melting point of resin?: Bisphenol A epoxy resins, like other polymers, are not a single molecule of relative molecular weight, but a mixture of homologous molecules with different degrees of polymerization. Therefore, not only the average relative molecular mass has a great influence on the properties of the resin, but also the relative molecular weight distribution has a great influence on the properties of the resin. The bisphenol A epoxy resin, the average molecular weight is determined by the size of the epoxy resin content, hydroxyl content, resin viscosity, softening point and solubility properties have great influence on the curing process, and the cured resin properties and applications. For example, resins with relatively low molecular weight can be dissolved in aliphatic and aromatic solvents, while resins with relatively high molecular weight can only be dissolved in strong solvents such as ketones and esters. The relative molecular weight distribution will affect the crystallinity, viscosity and softening point of epoxy resin. For example, when the average molecular weight is the same and the relative molecular weight is wide, the softening point of the resin is low. Therefore, average relative molecular mass and relative molecular mass distribution are important properties of epoxy resin.

Q:I changed my igniter module and now my boiler heats up the house but it won't shut off automatically. I have to manually shut down the entire system. Someone please help.: Everybody seems to be recomending the bearded dragon. Let's get away from that and get you something more interesting. Check out chinese water dragons, as they are inexpensive, and quite cool looking, or if you want something really out of the ordinary, look up a couple species of uromastyx.

Q:I tru IE, Opera and Safari and this is what come out:ForbiddenYou were denied access because:Access denied by access control list.: Round pipes are easier to bend and to manufacture, also rectangular pipes have uneven pressure gradients inside and could lead to leaks. This is the same reason airliner windows are rounded and not square, due to cracks forming in the fuselage from a-symmetrical stresses forming pressure points.

Q:My husband and I are shopping for our first baby, a daughter.Where is the best place to buy baby clothing and that is not 20 bucks for a single oneiseI shop now at Resale shops but I would like our daughter to have a few new things.Also we are still looking for a Nursery set and we want new just for the safety reason. The Crib and Dresser we picked out is 900 dollars plus delivery from Babies R Us. We LOVE the set but don't love the price.: Hey Don't be worried. Roller-coasters are designed to be perfectly safe. Before they even start a safety inspector comes around to check that the straps or safety barrier fits properly. They will tighten the safety bar so it fits you. Dont worry these people are pro's at their job. There is only a small chance that it won't fit but that is very, very, unlikely. If it wont fit then they will simply tell you tohop out. But i dont think that, that will happen at all. Roller-coaster are a hole lot of fun so get out there give it a go and Have fun. I hope this helps you. Have fun!!

Q:I know about astronomical tug-of-war, so how do satellites orbiting our moon not become unstable and just orbit Earth?: Could be anything. You need to call a repairman. Or you could invite a knowledgeable friend over to look at it.

Q:why is the blanket is wrapped on the burning object,in case of fire?: BASS Fisherman is exactly right. A GLX series G Loomis rod for $345-445 and Shimano Calais DC 4x8 reel $649.99. Best $1095 you could ever spend on bass tackle. Of course this rod comes in 14 different styles, sizes and actions and you will want a minimum of 1 each (maybe 2 each) for a grand total of close to $15k. Line, lures, bait are all optional (of course). Team Daiwa Steez looks like a bargain at $950 but you don't get the digital feature of the Calais DC. If you want the very best those are your options as far as freshwater factory bass tackle goes. Custom built rod tapers will obviously set you back several more $. Saltwater gear is going to cost you WAY more for the best. All you people that think an Ugly Stick is the best have very good sense of humor.
