Dodecyl alcohol ester is widely used in building and decoration materials in our country as a very ideal film-forming aid. Alcohol ester twelve is a strong soluble Chemicalbook agent for latex polymers and has very good hydrolytic stability, high coalescence performance, and a wide range of applications. Membrane aid. Mainly manifested in the following aspects. 1. It can reduce the minimum film-forming temperature of latex paint: Alcohol ester twelve has a prominent solvent effect, that is, it has a strong coalescence ability. In the case of using a small amount, it can effectively reduce the minimum film forming temperature MFT of latex paint, and can expand the use range of latex paint using high glass transition temperature polymers under different ambient temperatures. 2. It can promote the film formation of latex paint: it has low water solubility and is easily absorbed by latex ions. It can be directly contacted and is easier to swell the colloidal particles; its volatilization speed is low, and it remains in the latex paint coating before film formation. The effect will not be affected by the volatilization of water, and the continuity of film formation is good; and it has a suitable volatility, which will be completely volatilized in a short time after the latex paint film is formed, and will not affect the expected hardness and hardness of the latex paint formula design. luster.
