Packing：310ml cartridge, 25kg pail can, 250kg drum
Curing Condition：23±2C/50±5%RH for 7days
Handling precautions
KE-4928 reacts with moisture in the air and begins to cure at the surface. Consequently, the cure speed
will vary according to the temperature and humidity of the use environment. In addition, please note that if
humidity exceeds 100% and water droplets form on the curing rubber, a hydrolytic reaction will precede the
cross-linking cure reaction, which will reduce the strength of the post-cured rubber and remain surface
tackiness.
The electrical insulative properties will temporarily decline during the curing process. But in nearly all
cases, KE-4928 exhibit its inherent electrical insulative properties once completely cured. Please note that in
some cases, KE-4928 may not cure if it comes in contact with flux or certain other materials.
Do not use condensation cure products in a completely enclosed space.
Completely remove water, oil, dirt, and contaminants from the surface of the adherend. For certain
substrates, use a primer as needed.
When using an air gun, do not exceed 0.3MPa.

Usage
Surface cleaning
Using sandpaper or a solvent (toluene, xylene, etc), thoroughly clean the surface to remove all foreign matter
such as rust, oil, dirt, and grime that may impair bonding. Use caution when cleaning plastics with solvents, as some
solvents may damage certain plastics.

Application of primer
Apply uniformly using a brush or other tool. Be careful that no spots are missed, as there may be poor
adhesion in those areas.

Cartridge type
Operation: Grasp the handle/trigger of the loaded caulking gun and squeeze to eject the contents.
Storage: If possible, use all at once. If some material remains, use the removed nozzle end as a plug and seal
tightly resealed, the product can be stored for several days.

Storage precaution
Stored between 1～30C, out of direct sunlight.

Safety and hygiene
Be sure to provide adequate ventilation when using KE-4928. During curing methanol gas is generated. If
you experience any unpleasant symptoms please move to an area with fresh air.
Uncured KE-4928 may irritate skin and mucous membranes, so avoid eye contact and prolonged skin
contact. In case of accidental eye contact, flush with water for at least 15 minutes and see a physician. In case
of skin contact, immediately wipe off with a dry cloth and wash with soapy water. Contact lens wearers should
exercise adequate caution; if uncured KE-4928 enters the eyes, the contact lens may become bonded to the eye.
When using, be careful not to rub the eyes with the hands. Please take appropriate precautions such as
wearing safety glasses.
Make sure that work area is well ventilated. Be careful not to inhale vapors from the products used.
Keep out of reach of children.
