About this item:
PC-7 is the tough job epoxy. This paste epoxy was formulated for maximum bonding power. When mixed, components A (grey) and B (black) reacts to form a bond of tremendous strength. PC-7 formulation provides extended working time, for large and critical jobs, which allow the user to reposition work or make changes. High "wet grab" or tack of PC-7 Paste Epoxy makes overhead and sidewall work easy without drip or sag. PC-7 demonstrates excellent chemical resistance to mild acids, caustics, detergents, gasoline, fuel oil, salt, and fresh water. Approximately equal amounts of A and B by volume; variations of either component as high as 20 percent will not affect the bond strength. When desirable, one part of A to two parts B may be used to increase elasticity (expansion joints, etc.). In cold or cool temperatures, place PC-7 container near heat prior to using. PC-7 mixes and spreads easier at 80 degree F than at 40 degree F. Any clean smooth flat surface is an excellent surface for mixing and working. A small putty knife or flexible artist spatula are great tools for mixing and applying PC-7. Use with as adhesive: wood, metal (all types), glass, brick, block, rubber, concrete, stone, slate, fiberglass, tile, and more in any and all combinations; as sealant: oil, gas, water tanks, cellar cracks, pressure tanks, and plumbing leaks; as a filler: holes, castings, patterns, molds, voids, welds, steering wheels and much more. Work time (70 degree F): 60 minutes. Tack free cure time: 160 minutes. Cure for service: 24 hours. Maximum cure: 7 day. Gardner impact resistance: 160 in./Lb. Conduction (electric): non conductive. Excellent thermal shock. Non toxic once cured. Heat range: -20 to 200 degree F.

5.0 out of 5 stars Rock hard but not brittle
(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } Consistent good results:I used it for two weeks now and made about 6-7 batches to glue metal banisters into the handrail of my staircase. Each batch cured well and there seems no difference in the end result despite the fact that I didn’t measure anything. I just eyeballed as best as I could.Work time:I actually don’t know! I used each batch within about an hour after mixing at about 70 degrees and low humidity. I noticed it got a little stiffer, but otherwise still as sticky as before.Cure time:After 24 hours it was very hard but had some minimal flexibility and after 48 hours it appears fully cured. However, this material doesn’t become brittle, which is important for my application as there is always going to be movement between the wood and metal.Consistency of paste and mixing:Each component has a distinctive different consistency. The light gray (part 1) is somewhat crumbly, grainy and slightly sticky. You can get it easily out of the can and reasonably well of the spatula that I used to scrape it out of the can. The pitch-black hardener (part 2) is a totally different story. It is annoyingly sticky and although thick, will slowly flow. Think of ultra-thick honey. This makes it a pain to get out of the can and very difficult to get off the spatula.Now to the mixing part. Somewhat difficult because it is sticky and thick, but within 3-5 minutes you end up with a dark grey paste that has the consistency of chewing gum. When you try to lift a small amount off the mixture, you will stretch the material until it gets thin enough to break off. For me, the best tool was a disposable chop stick which I rolled back and forth to capture the stretched-out material.Stickiness:I had to work it into the wood grain for it to stick well. For example, if I would drop a small amount on a smooth surface, I would suspect you could easily pry it off once it is cured. But once it is pressed into place it will never come off.Flow properties while uncured:As I alluded to before, this material will flow a little bit over the course of 1-2 hours. In my case, I had to smear it into the holes at the bottom of the handrail. It worked reasonable well, but you can't put too much in the hole or it will slowly flow out.
5.0 out of 5 stars STRONG, FLEXIBLE, WORKABLE
I find a lot of excellent and helpful reviews here that all acknowledge that this is a demanding and challenging material to work with UNLESS you know what you are doing and THEN it is a very strong and long lasting material with many uses. Xylene is practically necessary. The value of being able to clean mixing surfaces and application tools INSTANTLY can't be overstated. This is probably the most difficult mixing I've seen with any material but it always works with the right tools and a little patience and the result is a heavy thick paste that gravity can sag before it fully sets hours later. That elastic strength is why it is one CRITICAL step in many demanding situations. I often like to use a thinner penetrating mixture first and follow it with this before fully cured until almost flush. Then I will usually finish with a finishing mix skim coat. Works great for me. I recommend every handy man or woman that doesn't know this stuff to get some to experiment with. Then you'll know what you're doing and what you can do with it. It lasts for years, even half used. I won't be without some on hand. Note: don't try to work this before it is half cured when you can scrape and carve it beautifully with different tools. Sanding shouldn't be attempted before full cured. Once cured, a lot of rocks wish they were this strong and the bond will be crazy good if you follow the easy steps.
5.0 out of 5 stars Use this for all types of environs and projects including acids, fuels, enamel reducers, etc.
It works great, The reason I could not give it higher marks is because you must know what the heck your doing. The epoxy and the resin hardener are not easy to mix and equal portions is most important. It is not a liquid or a gel or even a paste it is a very stiff substance, like C4. But please note that this is where it's strength comes from, and it is not 'easy' to be spread, you should have the right tools and know exactly what you are going to do with it. Cleanup will require something strong if you make a mistake (xylene). The important thing is you can fabricate anything , I have even used it the weld two pieces of hardened plastics. This will outlast any 3D printed piece , and I have used it even on my siding that had a couple of bullet holes. I applied the material in a measured amount, using a flexible putty knife. Then I removed any excess with the aforementioned solvent. A day later in 40 degree weather it hard enough to apply a small hand sander to feather out. Then I painted over it- and viola- bullet holes are gone and can now sell my house without question. Fixed broken lamps, works great with metal and glass and hard synthetic surfaces. Not the best for softwoods- lastly- as long as you don't mix it it will last forever- I still have some that was from 35 years ago, and I tried it wondering how it would do. The catalyst did take about twice as long to work but in two days it was as hard as a rock- It's aquarium safe- but wait a few days for complete cure and then was product of with soap and rinse well
4.0 out of 5 stars Works well, but tests your patience
Thia epoxy , when mixed properly has a very “gooey” consisdency. It bonds well and eventually does harden, but working with it is difficult because its consisdency is similar to a slightly thin peanut butter. As a filler it doesnt work well in horizontal uses. Its too flowable.If you want a “putty” type epoxy this isnt it. Its close, but not quite . It’s also very sticky. Hey, its glue! For my application I had to clean out the area of this epoxy with paper towels and use JB weld. Also, be aware, cooler weather requires 24hrs. Plus to set up .
Boîtes minuscules

Il y en a à peine plus que dans un gros tube de colle. Bien fait pour moi j'aurais du regarder plus attentivement la contenance. Pour du modelisme ça va... pour un bateau c'est autre chose.
Exactly what I expected but damaged in shipping
This product is awesome. I have purchased it twice. The first delivery arrived as cans in a box without any padding whatsoever. Although the product remained sealed despite dints, but that was lucky. The second delivery arrived with minimal padding that allowed the product to bang around in the box. Same problem appeared including rim damage. I'm hoping that this will not compromise the product as it is stored until use. Clearly this heavy product in cans requires sufficient padding for shipment.
Asquerosa
Está resina es verdaderamente una porquería. La probé varias veces y no hay manera de que solidifique correctamente. Cero recomendable
