RTV Silastic 1080
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
1. A Dow Corning (owners of Silastic & Molykote
Brands) product.
2. Ease of use - one part, no mixing required,
Non slumping, Non shrinking.
3. Can be applied to overhead or vertical
joints.
4. Does not crack, crumble or dry out in direct
Sunlight.
5. Excellent temperature range -65 °C to + 232
°C. Upto 260 °C for short periods.
6. Bonds almost all surfaces: Clean
metal-including chrome, painted surfaces,
glasses, ceramics, most plastics, non-oily
woods, fibrous cement and concrete surfaces.
7. Chemically stable.
8. Excellent resistance to weathering,
vibration, moisture, ozone under extreme
temperatures.
COLORS
Clear.
USES
1. Sealing of lock seams, welds and fasteners in
metal fabrication.
2. Sealing dissimilar metals and corrosion
sensitive surfaces like Chrome, Copper and
Steel.
3. Bonding and sealing appliance parts.
4. As formed-in-place gasket it replaces
conventional cork, paper, and rubber gaskets on
bear boxes, differential housing pumps and
compressors.
