NuSil™ R-2560

• Two-part, pourable, red RTV silicone
• 100:0.5 Mix Ratio (Base: Curing Agent)
• Based on a dimethyl diphenyl silicone copolymer with a broad temperature range
• Fast cure

• For potting, sealing and bonding applications
• For thermal insulating as a firewall sealant or as an ablative coating in missile, rockets, aircraft and launch equipment
• For applications in extreme temperatures
• For applications requiring an operating temperature range of –115°C to 260°C (-175°F to 500°F)

Mixing

Thoroughly mix just prior to use by adding 0.5% by weight catalyst to base. Work Time may be extended by using as low as 0.1% curing agent. Caution: R-2560 catalyst may cause skin irritation. In case of eye contact, irrigate with water immediately and seek medical attention. (Standard catalyst is dibutyl tin dilaurate.)

Vacuum Deaeration

Remove air entrapped during mixing by common vacuum deaeration procedure, observing all applicable safety precautions. Slowly apply vacuum, up to 28 inches Hg, to a container rated for use and of volume at least four times that of material being deaerated. Hold vacuum until presence of air is no longer evident.
