    摘要: Low shrinkage sheet molded composite (SMC) formulations and methods for producing low shrinkage sheet molded composites from the SMC formulations are provided. Thermosetting low (LPA) profile additive compositions and the use of thermosetting LPA compositions in producing low shrinkage sheet molded composites are also provided. The LPA compositions allow for the production of sheet molded composites with a high quality surface profile which have both high mechanical and dimensional stability.

    摘要: Disclosed is a process for the catalyzed reaction of an isocyanate and an active hydrogen compound wherein the reaction is conducted in the presence of a novel catalyst comprising the salt of 1,8-diazobicyclo(5.4.0)undec-7-ene and 1,4-benzoquinone. Preferred catalyzed reaction mixtures comprise Reaction Injection Molding urethanes (RIM). The novel catalyst salts provide a controlled induction period prior to the onset of gelation of the reaction mixture while providing complete cure of the reaction mixture thereafter.
