Development of high performance waterborne two component polyurethane topcoat was written by Zhang, Yi. And the article was included in Shanghai Tuliao in 2014.Formula: C7H14O3 The following contents are mentioned in the article:
The raw materials selection and development process of waterborne two component polyurethane topcoat were introduced. The influences of hydroxyl containing dispersions, curing agent, additive and cosolvent etc. on the gloss and fullness of film were discussed. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Formula: C7H14O3).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Formula: C7H14O3
