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
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
Bonds almost all surfaces: Clean metal-including chrome, painted
surfaces, glasses, ceramics, most plastics, non-oily woods,
fibrous cement and concrete surfaces.
Excellent resistance to weathering, vibration, moisture, ozone
under extreme temperatures.
