- Instructions for Use
Mixing
Mix at a 1:1 mix ratio when extracted from their side-by-side kits through a static mix and dispense cartridge. Attach the disposable static mix tip to the cartridge and extrude the product directly onto the substrate. Note: NuSil Technology recommends discarding the first few grams of extruded material. Can also be purchased in standard two-part kits. When using standard kits, take care to minimize air entrapped while mixing. Place the mixed product in a vacuum chamber to remove entrapped air and subsequently reduce bubble formation during curing.
Substrate Considerations
Cures in contact with most materials common to electrical and electronic assemblies. Exceptions include: sulfur cured organic rubbers, latex, chlorinated rubbers, some RTV silicones and unreacted residues of some curing agents. Clean units being encapsulated or potted to ensure they are free of contaminants. Also clean and dry containers and dispensers being used. Prevent cure inhibition by washing all containers with clean solvent or volatizing the contaminants by heating.
Note: Some bonding applications may require use of a primer. NuSil Technology CF1-135 silicone primer is recommended.
Adjustable Cure Schedule
