Acrylic adhesives are not the same as acrylate adhesives, and acrylate adhesives cannot be used as acrylic adhesives.

The difference between acrylic acid and acrylate:

First, the concept is different:

Acrylate refers to a general term for esters of acrylic acid and its homologues, and acrylic acid is only one type of acrylate. More important acrylates are methyl acrylate, ethyl acrylate, 2-methyl methacrylate and 2-ethyl methacrylate.
Second, the chemical formula is different:

Acrylate chemical formula: CH2=CHCOOR

Acrylic chemical formula: CH2=CH-COOH

Third, the use is different:

Acrylic acid: It is the most basic chemical raw material. It can not be used in the end products of fine chemicals. It has strong acidity and is close to hydrochloric acid. It is generally used to synthesize acrylate compounds.

Acrylate: It is obtained by reacting acrylic acid with an alcohol. It can synthesize many oligomers and copolymers. These oligomers or copolymers are simply referred to as resins, and can be used as coatings, inks, adhesives, and the like.
