Directions for Use
Remove the damaged part, burs carefully.
The dispensing surface should be clean and free of grease.
Avoid to contact with the material that can inhibit cure,
Including organic matter which contains N, S and P
Element, metal compound which contains organotin,
Silicone rubber which contains organotin, amine,
Polyurethane, amine-containing materials, unsaturated
Hydrocarbons, sulfur-containing materials, sulfur,
Polysulfide, polysulfone, welding machine residue.
Darbond high efficiency metal cleaner 2577 is
Recommended.
Weight A and B component accurately.
Mixing: Mix A and B component thoroughly, adopt
Vacuum deaeration when necessary.
(There may be some deposition at the bottom, shake A and B
Component evenly before use. )
Potting: Mixed material should be used up within pot life,
Otherwise viscosity is too high to pouring.
Cautions
Keep out of reach of children.
In case of contact with skin, wipe away, then rinsewith clean
Water immediately; If contact with eyes, rinse withclean water
Immediately and call a physical attention.
