Question

I just saw this video about using baking soda + cyanoacrylate(CA) glue as a substrate+resin.

Neat, but do CA and NaHCO3 react in any way?

If so, what does the equation look like and what is the resulting structure?

If not at room temperature, do they react at higher temperatures because CA curing is exothermic.

Is the CA + NaHCO3 stable once it dries, is there any residue that would be toxic or irritating?

Answer 1

When baking soda (sodium bicarbonate, NaHCO3) and cyanoacrylate glue (CA) come into contact with each other, they do not react chemically. The presence of NaHCO3 does not affect the curing process of CA. Once CA and NaHCO3 dry, they do not undergo any further reactions and are stable.

Step-by-step explanation:

When baking soda (sodium bicarbonate, NaHCO3) and cyanoacrylate glue (CA) come into contact with each other, they do not react chemically. This is because cyanoacrylate glue, commonly known as super glue, is a type of adhesive that is made up of a polymer chain and does not contain any reactive components that can react with baking soda.

Therefore, there is no chemical equation that can be written for the reaction between CA and NaHCO3.

At room temperature, CA and NaHCO3 do not react. CA curing is exothermic, meaning it releases heat during the polymerization process. However, the presence of NaHCO3 does not affect the curing process of CA.

Once CA and NaHCO3 dry, they do not undergo any further reactions. The dried CA plus NaHCO3 mixture is stable and any residue left behind is nontoxic and non-irritating. Baking soda is a common ingredient in many household products and is generally safe to use.
