When the content of PA21 was equal to that of K125P, the q values of PA21 and K125P were close to each other, but greater than that of ACR401, which showed the adhesive force of PA21 and K125P were very strong and stronger than that of ACR401.

• 在相同用量下,PA21与K125P的q值非常接近,但比ACR401大,说明PA21与K125P的粘附力相当,且都比ACR401大。
