"nontoxic: zein protein from corn, and tannic acid... water type does not influence performance much but substrate type does... protective skin formed when underwater... once in place can be broken inducing faster bond formation... maximum bonding at 30°C then another increase at higher temperatures... coral reef restoration, construction, manufacturing, biomedical, dental, food and cosmetics"
