Abstract
Inventia se refera la un liant cu autoîntarire pentru forme si miezuri de turnatorie, constituit dintr-o rasina alchidica modificata, rezultata prin policondensarea amestecului de anhidrida ftalica si maximum 12% pentaeritrita în prezenta uleiului de soia si a unui adaos de 1% NaOH, din 20-22% white-spirit si din 4,8% solutie sicativa colectiva de naftenati de Co, Pb, mn în xilen si white-spirit, în sine cunoscuta. în scopul obtinerii unor forme si miezuri calitativ superioare, liantul contine drept component de baza rasina alchidica obtinuta prin policondensarea anhidridei ftalice în amestec cu minimum 10% pentaeritrita, în prezenta a 60-65% ulei de soia.
