It seems like STEM toys never cease to amaze. Every year, we see an abundance of phenomenal products for young and old children alike. So, what can parents get their 4 – 5-year-olds to play with?
“Hydrophilic” literally means water attracting, as such a hydrophilic coating results in water molecules being attracted to the surface. Hydrophilic coatings and treatments are typically utilized to enhance surface lubricity, minimize surface friction or for applications where having a surface that fully wets out when exposed to moisture is desirable. Most hydrophilic coatings are hygroscopic and will readily absorb moisture when exposed to it. These saturated coatings have significantly reduced friction while wet resulting in drastically reduced pull forces and coefficient of friction.
