Detailed Product Description

Description

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 constructions.

Characteristic

It has Good features as follow:

aCan be easily used and extruded any time.

bExcellent contact change and extrusion ability, in any air temperature( -40 to 100) can extrude easily.

cExcellent adhesion to stone, ceramics, concrete, and other building materials. It has no pollution to porous materials.

dOutstanding weatherproofing ability. Excellent tensile and compression restoring ability. It can bear joint movement capability of ±20%.

eNeutral 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.

Use limitations

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
