Water proofing agent and leveling agent, what is the difference?

1 waterproof agent, by some very low surface energy of material composition, be formed on the surface of continuous coated waterproof layers, due to the surface tension of water (pure water 25 degrees 72mN/m) is greater than the waterproof layer (about 18-28mN/m), water is not attached to the surface of the coating, so the relative called the waterproof layer. Is a kind of functional additives.
2 leveling agent (Rheology modifier), is used to change the fluid rheology additives, such as fluid illiquid add rheological agent can improve liquidity in coatings industry sagging preventing agent also uses this principle: the vertical surface of the construction paint flow affect the construction quality, add rheological agent to prevent sagging, paint thinning convenient construction in roller or brush pressure, recovery of pseudoplastic prevent flowing pressure disappears. Leveling agent is a kind of to reduce the surface tension of the fluid additives, also has the change of surface wetting / coating surface flatness and smoothness of function.
