- Instructions for Use
Processing
Thoroughly mix Part A with Part B in a 1:1 mix ratio by weight or volume. Airless mixing, metering and dispensing equipment is recommended for production processing.
Mixing and Vacuum Deaeration
Thoroughly mix Part A with Part B in a 1:1 mix ratio by weight. Remove air entrapped during mixing by common vacuum deaeration procedure. Prior to deaeration NuSil recommends verification of the work time of the material, and observation of 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. Apply the vacuum while observing the uncured fluid for presence of bubble formation and increase vacuum slowly enough to avoid rapid foaming. Hold vacuum until presence of air is no longer evident.
NuSil recommends selecting side by side kit packaging (i.e. 50 ml cartridge) if unable to perform the de-airing procedure above or mix and meter equipment is not available due to the pot life of the material.
Substrate Considerations
Cures in contact with most materials, exceptions include: sulfurcured organic rubbers, latex, chlorinated rubbers, some RTV silicones and unreacted residues of some curing agents.
Note: Some bonding applications may require the use of a primer. NuSil Technology’s CF1-135 is recommended.
Adjustable Cure Schedule
Product cures at a wide range of cure times and temperatures to accommodate different production needs. Contact NuSil Technology for details.
