IdeaPaint’s Letter to an Inquisitive Fan


We recently received a very sweet letter from an inquisitive fan, Nikki. She wondered: how does IdeaPaint work?

Curious yourself? Check out the correspondence below.

Dear Sir or Madam: 

My name is Nikki and I am in sixth grade at Silverbrook Elementary School in Fairfax Station, VA. I would like some help on a science research project. I am doing a paper on how white board paint works. Specifically on how the molecules and chemicals bond to let you write and erase on it. I would like it if you or someone at Idea Paint can tell me how.   If you can’t, could you point me in the right direction?  I would really appreciate if you could help me with some information.

You can write to me at my email address listed below.

The question: What makes dry erase paint work? How do the molecules orient themselves to chemical bond and/or structural link in order to achieve a dry erase paint that allows one to write and erase? 

The answer: The dry erase paint comes in 2 parts, Part A is the main resin and Part B is the hardener.  Both parts when mixed together begin to bond with each other.  The part A  molecules are friendly and they like to bond with the molecules in the Part B hardener.  However, the hardener is sometimes a slow poke and needs a little push.  That’s where catalyst comes to the rescue.  Catalyst helps in telling the hardener that it has to makes friends with the resin.  How does it do this, by holding hands.  They hold hands so tight that the bond is unbreakable.  This bond is sometimes so strong what happens is the overall force, resulting in sometimes heat, will release small amounts of carbon dioxide gas, this gas has to be forced out of the way in order for the final film to be ultra smooth for the dry erase property.  Our army for that is the additives, they take control of the task in making the paint look and feel as smooth and glossy as it needs to be in order to make it look pretty.

Now while all this is going on, the bond will continue to multiple to the point that there is a no longer any more bonds to be made and the film reached its maximum strength.  This strength is what determines the dry erase to have its write and erase properties.  Sometimes though this bond can be latent, that is it may need a few days to achieve its full strength before its full ability to be the perfect dry erase write and erase paint like IdeaPaint.

I hope this helps!! 

We’re glad to help out a curious fan, and doubly as happy that these are questions percolating in the brains of elementary school students. Wonder what Nikki will end up inventing!
