On synthesis ways of biuret-containing polyisocyanates
Dan Peng · Adhesion in China · 2008
Polyisocyanates which contain biuret groups are important curing agents.However,none of the domestic companies can produce such kind of compounds at present and they depend on importation.The overseas techniques of preparing biuret-containing poly- isocyanates by different biuretising agents and the focused research aspects in recent years are reviewed in this paper.The benefits and deficiencies in every technique are also introduced,in order to provide reference information for the domestic research.
