Is acetone an acid?
No. Acetone is a ketone. Acetone is CH3COCH3 Ether is of the type R-O-R
Is acetone a weak acid?
Acetone is not a acid it is a ketone. It doesn't have H+ ions to liberate so as to act as an acid.
What are resin in gymnosperms?
Resin is a waxy substance that gymnosperms secrete in their resin canals that act as an anti-freeze for the plants. This is why gymnosperms are the evergreen trees and they do not lose their needles.
Is acetone a weak base?
Acetone can act as a base or and acid, depending on the nature of the other reagents and the reaction conditions.
Can you Paint over Latex Primer with Epoxy Primer?
Epoxy primer has to go over a bare surface otherwise it can act as a stripper, causing the base coat, along with the newly applied epoxy to delaminate or lift from the surface.
Can you put clear poly over epoxy?
Yes, you can on some one-part epoxies; however, be sure to check the data sheet for the epoxy. Most solvent based epoxies will act as a remover when placed over polyurethane.
What kind hull does a pwc have?
The most common hull material is fiberglass, often with an epoxy resin outer coating. The most common hull design is a modified-V, sharper at the bow and progressively softer as you move further aft. Many PWCs have sponsons, fin-like structures at the rear on both sides. They act like rudders, improving handling in tight turns, and they also act like floats, improving stability.
Can you super glue a plastic gas tank?
Of courseANS 2 - Better to epoxy it as the gas may act as a solvent on the super glue.
What is the purpose of acetone in indigo synthesis?
the former answer is incorrect. While Acetone is clearly a reactant and it is used to dissolve the 2-nitrobenzaldehyde, it is NOT a reducing agent. To say it is a reducing agent is to say it OXIDIZES the compound. Only later when the leuco-indigo in the fabric does oxygen act as the reducing agent and oxidize the indigo, setting it in the fabric.
Should you sand before applying epoxy over oil based paint?
You should remove the oil based paint before applying the epoxy. Many epoxies will actually act as a remover when put over oil-based paints.
Can you put epoxy concrete sealer over acrylic sealer?
Of course you can. You can also scribble a mustache under the nose of a Picasso painting and use dirt as a condiment for your hotdog but none of these are good ideas. The question isn't one of whether or not it can be done but, what the chances of long-term adhesion are between the acrylic sealer and the epoxy coating.As far as the two materials are concerned, it's really a pretty generic question because both epoxy coatings and acrylic sealers come in a multitude of different varieties and formulations. So, the answer will have to be equally generic.First and foremost, any run-of-the-mill epoxy (bis-A, bis-F, novolac, water, solvent or 100% solids, etc.) will adhere, to one degree or another, to a clean, contaminant-free polymer treated surface as long as the formulation, mixing and application are done correctly. The chances of a higher rate of adhesion increase when a profiled surface (increased surface area) is available.However, in the same way that a concrete foundation designed and poured to support a single-story residential home isn't well suited to support the weight and movement dynamics of a ten story building, a single-component acrylic sealer isn't well suited to act as the foundation for a two-component crosslinking epoxy. The long and the short of why this is true is simple:Acrylic sealers typically have a solids content of between 20-30%.This means that once the carrier (which is usually water or solvent), that makes up the counterpart to the solids content (70-80%) has evaporated, the solids are what remain on the surface as the dried sealer.When examined microscopically, the solid particles appear as individual and independent specks.Conversely, all two-component epoxies crosslink forming carbon chains, which make the epoxy coating a single sheet (like a roll of plastic) once it's cured.When exposed to enough stress (think foot or wheeled traffic) the individual solid acrylic particles can act as an epoxy bond breaker because they inhibit the epoxy coating from making full contact with the surface that it's intended to protect.In summary, although it's not recommended and assuming the sealer is in tact, if an epoxy is going to be used to coat an existing acrylic sealer (for whatever reason), it would be best to use either a 100% solids or a water-based epoxy to avoid any possible attack from an epoxy containing solvent.With all this said, the best approach is to fully strip and eliminate the sealer so that the epoxy coating can have access to a well prepared, open and porous surface.
Function of iodine in staining?
iodine act as a mordant..on the gram positive bacteria which got really thick and abundence of peptidoglycan layer, the crystal violet will fix to the peptidoglycan layer..meanwhile in gram negative bacteria which is lack of peptidoglycan layer, the alcohol or acetone will wash it away
