Installation
Surface Preparation and Use
Use gloves, wear eye protection, and avoid skin contact. When grinding
cured joints, wear a dust mask. Substrate to be bonded must be completely
dry and dust free. Mix only the amount of epoxy which can be used in
10 minutes. Avoid stressing joint before complete cure of epoxy. Mask
areas which must be kept free of epoxy. Clean uncured epoxy from tools
with toluol (toluene) or xylol (xylene). (Use caution, these solvents
are flammable. Ensure local ventilation.) Remove cured epoxy mechanically.
Mixing Instructions
The unmixed epoxy components should be at or above 45°F. Combine
the two ingredients at the following volume ratio: one part A-199 to
one part B-439-T. Mix thoroughly--- ingredients must be blended homogeneously
for proper cure. Best to mix using double mix method. See reverse side.
Temperature
Dependency
This product is unique and cures at below freezing temperatures. Most
setting properties are independent of curing tem- peratures between 20°F
and 100°F.
