IDEABOND 793 GENERAL PURPOSES 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 perimeter joints in buildings and other constructions.
●Characteristic
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. Outstanding weatherproofing ability, excellent tensile and compression restoring ability.
●Where to use
IDEABOND 793 is general purposes used on different material, coz it is neutral curing, and no harm to most of substrates.
●Use limitations
IDEABOND 793 is not fit for structural usage:
a. To all materials that bleed oils, plasticizers or solvents, and green or partially sulfur zed gaskets and tapes, etc.
