Will this violate international electric code to seal outlet boxes from the inside? Draft protection.

First of all, there is no such thing as an "international electric code". There are electrical safety standards that are used internationally, but whereas a "code" is concerned, that is local to a nation, and in many cases local to a state or province, and even to a city. What matters here, though, is the electrical safety certification for the outlet box, and in the US, compliance to the NEC (National Electric Code), aka NFPA70. Adding sealant that isn't part of an outlet box's design may or may not be a problem. To determine that, you need to check the outlet box's manufacturer's instructions. If their electrical safety approval for the box allows for a user's addition of material, and/or the addition of the material can't impair safety, then it's probably OK. One thing to note: if the outlet box is for inside the wall, and you are trying to use it outside by sealing it, that would indeed be a violation of the NEC as well as the intended use of the box. One thing to keep in mind: home owners can do what they want, and their own safety is up to them, but where it matters is liability to other people if a non-compliant installation caused a fire that harmed others, and also when you go to sell your house - an inspector will catch it, and you'll have to have a professional fix it (the buyer, their Realtor, and/or their lender will insist on that).

Is this sticky? and Reusable?

It is *very sticky* and probably not reusable.

do these come in individual boxes? i do not see one pictured.

My husband said yes, they are individually packaged

Can this be used as an acoustic putty around outlet boxes?

We are using it for increasing the wall thickness our our drian locks, you can check with the mfg directly and see if they recommend it fo rthat application

Excellent product

I bought this to fill out the ribs on the roof of my van in order to mount a roof light. I'm very pleased with the result and it hasn't leaked. Brilliant product.

Edges of tape dont stick.

Bought for my bike for underneath stone chip protection. It sticks okay enough but about 2mm from the edge on both sides the stick is almost non existent. Cleaned frame with alcohol wipes before hand. It appears the edge of the band has become dry. Maybe it's old stock. Either way I wouldn't buy it from amazon again.
