Description :
Silastic 1080 RTV Silicone Sealant is a one part, Neutral (Non
Acid) cure Silicone material of paste like consistency that
cures to a rubbery substrate when exposed to moisture in the
air. It is essentially recommended for corrosion sensitive
materials where acid - curing types of sealants cannot be
tolerated or where curing odours may be objectionable.
Important Features :
Ease of use - one part, no mixing required, Non slumping, Non
shrinking.
Can be applied to overhead or vertical joints.
Does not crack, crumble or dry out in direct Sunlight.
Excellent temperature range -65 °C to + 232 °C. Upto 260 °C for
short periods.
Bonds almost all surfaces: Clean metal-including chrome, painted
surfaces, glasses, ceramics, most plastics, non-oily woods,
fibrous cement and concrete surfaces.
Chemically stable.
Excellent resistance to weathering, vibration, moisture, ozone
under extreme temperatures.
Colors :
Clear.
Uses :
Sealing
of lock seams, welds and fasteners in metal fabrication.
Sealing dissimilar metals and corrosion sensitive surfaces like
Chrome, Copper and Steel.
Bonding and sealing appliance parts.
As formed-in-place gasket it replaces conventional cork, paper,
and rubber gaskets on bear boxes, differential housing pumps and
compressors.
Oven doors in glass-to-metal applications.
Caulking joints in ductwork.
Cement surfaces and metal pipes.
Attaching signs and sign-letters to metals, masonry and concrete
surfaces.
