It is low also autocatalysis crocking characteristic poly- all for density which possesses the aging quality which is improved polyurethane form catalytic action

摘要

This invention, furthermore, combination of this catalyst, aging quality, and little VOC which is improved (the volatile organic compound) is low also autocatalysis crocking characteristic amine poly- all and the gelation amine catalyst and being blocked with acid in regard to catalytic action, it regards the use in producing the density which possesses the discharge quantity polyurethane form.
