Success In Developing Flame-retardant Polyurea Material

- Jul 14, 2018 -

To prepare the flame-retardant spray polyurea coating with similar performance with the spray polyurea coating in mechanical property,thermal stability and surface appearance.The spray polyurea coating was perpared mainly from isocyanates(A component),polyether polyols and amine chain expanding agent(B component) by high pressure airless spraying.We added the solvent flame retardants in A component,and the inorganic filler type flame retardant in B component.The method to prepare the flame-retardant spray polyurea coating was the same as that of the spray polyurea coating.This is the specification of our flame-retardant spray polyurea coating.
