본 발명은 저온조건에서 제조되는 경화성 조성물의 사용시에 있어서, 점성조정제의 활성화에 기인하는 취급성 및 도포성의 악화를 개선하고, 더불어 에너지 절약이 가능한 점성조정제 및 상기 점성조정제를 포함하는 경화성 조성물을 제공한다. 디아민 성분(A1)과 모노카복실산 성분(A2)을 축합반응시켜 이루어지는 디아마이드 화합물(A) 및/또는 경화 피마자유(A')와, 아민 성분(B1)과 카복실산 성분(B2)를 축합중합시켜 이루어지는 폴리아마이드 화합물(B)을 함유하는 경화성 조성물용 점성조정제이다. 디아민 성분(A1)은 탄소수 2~12의 디아민으로 이루어지는 군으로부터 선택된다. 모노카복실산 성분(A2)은, 수소첨가 피마자유 지방산 및 직쇄 포화지방산으로 이루어지는 군으로부터 선택된다. 폴리아마이드 화합물(B)의 중량 평균분자량은 2000~21000이다. 경화성 조성물의 경화물은 실란트 또는 접착제로서 사용된다. To provide a rheology control agent capable of preventing deterioration in handleability and applicability caused by insufficient activation of the rheology control agent in use of a curable composition produced under low-temperature conditions and reducing the amount of energy used in production, and to provide a curable composition containing the rheology control agent.A rheology control agent for a curable composition includes: a diamide compound (A) and/or a hydrogenated castor oil (A'), the diamide compound (A) being obtainable by condensation reaction between a diamine component (A1) and a monocarboxylic acid component (A2); and a polyamide compound (B) obtainable by polycondensation of an amine component (B 1) and a carboxylic acid component (B2). The diamine component (A1) is selected from the group consisting of diamines with 2 to 12 carbon atoms. The monocarboxylic acid component (A2) is selected from the group consisting of hydrogenated castor oil fatty acids and linear saturated fatty acids. The polyamide compound (B) has a weight-average molecular weight from 2,000 to 21,000. A cured product of the curable composition is used for a sealant or an adhesive.
