SURFACE PREPARATION
Remove dirt, loose particles and oil contaminants by scarification, sandblasting. Then vacuum or blow clean with an oil free compressed air.
MIXING
Mix 1 part "A" Component with 1 part "B" Component using a low-speed, 1/2" mixing paddle for 3-5 minutes. Apply immediately. Apply by brush, roller or spray. May require heat for spraying. High temperatures will shorten pot life.
COVERAGE
125-150 square feet per gallon.
Force cures
must be used for enhancement of high temperature and chemical resistant
properties or to allow the coating to be placed in service before 5
days. Allow the coating a post cure of 12 to 24 hours before force
curing. RECOMMENDED FORCE CURE SCHEDULE |
CAUTION
WARNING! "A" Component contains Epoxy Resin. "B" Component contains alkaline amines; strong sensitizer. May cause skin sensitization or other allergic responses. Avoid inhalation of vapor. Use good ventilation, particularly if the material is heated or sprayed. Prevent all contact with skin and eyes. Wear protective clothing, goggles, gloves, and/or barrier creams. If contact with skin occurs, wash immediately with water and contact a physician.
FIRST AID: In case of contact, immediately flush eyes or skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Call a physician. Wash clothing before reuse. Discard contaminated shoes. Wear protective clothing, goggles, gloves, and/or barrier creams.
