Double component Ploysulfide Sealant
HJL two-component ploysulfide sealant is a two-component water
proof material which is singly packed and solidifies under ambient
tempreture.it is also called sealing paste because it is a
paste.the ploysulfide sealing paste is is based on liquid
polysulfide rubber,with addictive of various chemical assistants
and ploymer material,processed with special synthesis procedures.it
is a perfect poison-free water-proof sealing material.it features
good aging resistance and water resistance,adhesion and
elasticity.it could maintain good physical ,chemical performance
under codition of continous stretching,vibration and tempreture
change.it has good adhesion to many metal and non-metal materials.
It is applicable for the water proof sealing,crack repairing and
corrosion proof and water prof by coating for concrete deformation
joints such as expansion and settlement jionts in construction
including irrigation works and municipal engineering,undergroud
structures (tunnel ,subway ,pipelines for water supply and
drain),high-grade highway ,airprt runway,swimming pool and water
storage pool ,and for building nodes,expansion joints and
construction joints inassembly type buildings.

(1)Making the base surface clean ,dry and oil free.
(2)Adhering atain preventing tape on both sides of deformation
joints to keep both sides from staining.
(3)Full mixing component a(basic sealing past,yellow)and component
b (solifier ,black)in proportion of 10:1 in the container;also
acceptableto make the mixtures in proper proportion of 10:0.8-1.2
based on weather change.generally the mixing shall be conducted for
more than five minutes if mechanical mixing is adopted.
(4)Filling the ploysulfide sealing paste into the joints with
scrapers and scraping it even .generally the paste is filled in two
steps,with the first step of scraping the paste onto both side of
the joints,and second step of filling the joint and scraping it
.the paster gun may be ulilized ,the conpactness shall be checked
upon completion of construction ,and then the scraper used the tear
off the stain-proof tape .
5）The prepared paste shall be used within two hours,and otherwise
it will gradually solidify and cause difficulty to the
(6)It shall be kept from water and rain within 24 hours upon
completion of construction.
