- Instructions for Use
Mixing
Thoroughly stir individual parts prior to addition to ensure a homogenous mixture. Mix Parts A and B in a 1:1 ratio.
Vacuum Deaeration
Removed 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.
Note: Some bonding application may require the use of a primer. NuSil Technology CF1-135 silicone primer is recommended.
Substrate Consideration
LS1-6941 will cure in contact with most materials common to biomedical assemblies. Exceptions include sulfur-cured organic rubbers, latex, chlorinated rubbers, some RTV silicones and unreacted residues of some curing agents.
Adjustable Cure
Schedule Product cures at a wide range of cure times and temperatures to accommodate different production needs.
