POLYMER BLEND AND COMPOSITIONS AND METHODS FOR USING THE SAME |
摘要 |
The present invention relates to a polymer blend comprising:
a) at least one polysulfide component;
b) at least one polythioether component; and
c) the reaction product of a polysulfide, dimercaptodiethylsulfide and an
amine;
to a composition comprising said polymer blend;
to a sealant composition comprising said polymer blend and a curing agent; and to a method for repairing a first sealant, comprising:
i) applying the composition to the first sealant layer; and
ii) applying a second sealant layer thereon;
wherein either the first or second sealant layer is based on polysulfide chemistry, and the other sealant layer is based on polythioether chemistry. |
