APPLICATION label for this product.
Mixing - For Touch-Up Only
We recommend using Jiffy type mixers for all mixing and stirring. When
operating the mixer avoid plunging it up and down in the bucket. This can
fold air into the resin, which may cause bubbles to form in the coating after
it has been applied. Brush, roller or spray.
Individually stir each separate Part A and Part B component to a smooth,
uniform consistency and color. Any sediment in the container must be
thoroughly scraped up and redispersed.
Spray
Immediately before applying a spray coat, stripe all continuous welds
with a brush applied stripe coat. A stripe coat, applied by spray, may
be applied to all sharp edges to adequately protect these critical
areas.
Note: Force curing may be desirable in certain circumstances. Check
with Carboline’s Technical Service Department.
