- Instructions for Use
Mixing
Mix in a ration of 1:1:0.1, Part A: Part B: Part C. If mixing by hand, take care to minimize air entrapment while mixing.
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.
Substrate Consideration
Cures in contact with most materials common to electronic assemblies. Exceptions include butyl and chlorinated rubbers, some RTV silicones and unreacted residues of some curing agents. Units being encapsulated or potted should be clean and free of surface contaminants. Containers and dispensers should also be clean and dry. Prevent cure inhibition by washing all containers with clean solvent or volatizing the contaminants by heat.
Note: Some bonding applications may require the use of a primer. NuSil Technology LLC CF1-135 silicone primer is recommended.
Adjustable Cure Schedule
Product cures at room temperature and a wide range of elevated temperatures and cure times to accommodate different production needs.
