ZJ-888 Neutral Stone Silicone Sealant is a one-part, low modulus,
neutral curing sealant particularly suitable for interior and
exterior applications, in particular external weather seals,
expansion joints and perimetral joints in buildings and other
It has Good features as follow:
a. Can be easily used and extruded any time.
b. Excellent contact change and extrusion ability, in any air
temperature( -40 to 100) can extrude easily.
c. Excellent adhesion to stone, ceramics, concrete, and other
building materials. It has no pollution to porous materials.
d. Outstanding weatherproofing ability. Excellent tensile and
compression restoring ability. It can bear joint movement
capability of 20%.
e. Neutral curing, no corrosive to stone, concrete, and other
structural materials. Over come the weakness of acetic sealants
(normal glass sealants) erodes the materials.
Where to use
ZJ-888 is use to joints sealing in dry-hang for marble, granite
curtain-wall and precasting cement engineering; it is also use for
concrete construction and expansion joint sealing in highway
engineering; use to fix up sanitary equipments, adhesion and joint
seal for ceramics engineering; use to automotive, ship, packaging,
advertisement and family decoration.
ZJ-888 is not fit for structural usage. It should NOT be applied in
the following conditions:
a. To all materials that bleed oils, plasticizers or solvents, and
green or partially sulfur zed gaskets and tapes, etc.
b. In totally confined space (Silicone sealant need the water in
the air to cure)
c. For continuous immersion in water or below-grade applications
all the year.
d. To painted surfaces, may cause seal failure as the paint
cracking or paint stripping
e. To frost-laden or wet surfaces
f. Surface touch the food directly
g. Easily suffer mechanical clash
