Product Description
Liquid polysulfide rubber as the basic material, adding tackifying
resin, vulcanizing agent, accelerant and fortifier makes up the
two-component polysulfide sealant (double-component polysulfide
sealant). It is a kind of two-component sealant that can vulcanize
and crosslink by itself at room temperature. Its appearance is
exquisite and even paste or ropy liquid, so it is also called
two-component polysulfide sealing paste. It is made up of A
component and B component. A component is hoary even paste and B
component is black even paste. The two components have clear color
difference, which makes the mixing more convenient. The mixing
ratio is A : B=**0 : 8 - *2. It has good bonding effect to metal,
concrete and other material. It can keep good air tightness and
waterproof ability in continuous vibration and temperature
changes.
The classification of two-component polysulfide sealant:
It can be divided into two kinds according to the flowability:
non-slumping and self-leveling.
It can be divided into two kinds according to the movement ability:
*5 and *0.
It can be divided into two kinds according to the tensile modulus:
high modulus (HM) and low modulus (LM).
Features:
Excellent adhesion performance: it has good bonding effect to
cement, steel, glass, wood and natural stone.
Resistant to water: it is stable facing sea water, tap water and
distilled water.
It is not resistant to concentrated acid and alkali. But it is
stable facing the diluent inorganic acid, alkali and various
salts.
Excellent anti-aging and resistance to high temperature. It can
work in the temperature of **0°C - ***0°C for long time.
Resistant to ultraviolet.
Non-toxic, good air tightness and high elasticity. It has the best
air tightness among all the sealants.
Package:
Big packing: A component: **0kg/drum, B component: *0kg/pail.
Small packing: A component: *6kg/pail, B component: 3kg/can.
Packed as customers' requirements.
Shelf life: *2 months in the original unopened package stored in
dry and cool environment and the temperature not exceeds *7°C.
Color: A component is hoary, B component is black, and the mixture
is black.
Using method:
Clean the bonding surface to keep it dry and clean.
Painted the primer on the surface before construction. Glue
protective adhesion tape on the two sides of the joints after the
surface is dry to avoid the needless sealant pollute the
surface.
Mix A component and B component fully until no color difference. B
component should be more in winter and less in summer than normal
because of the climate difference. You should have a try before
using.
Squeeze the mixed polysulfide sealant into the joints with lime
knife or caulking gun until the joints being full. Then make the
sealant smooth with lime knife.
Take off the protective adhesion tape after the construction
finished and avoid to make the surface be exposed to rain within *4
hours.
Application:
It is widely used in sealing expansion joints and settlement joints
of buildings, subway, tunnel, airfield runway, expressway and
bridge.
It is also used in sealing various expansion joints of waterworks,
swimming pool, impounding reservoir, power station, retaining dam,
sewage treatment project and water supply and drainage system.
Note:
The mixed sealant should be used up within 2 hours, because it
cures gradually which makes the construction hard.
