PB303 cannot ship to other countries so is unavailable for purchase outside the continental US and Canada.
An activator is appropriate whenever you want an instant cure or hardening of your adhesives. It allows for instant handling of your specimens, with care, in many instances. Activator will cause all PaleoBOND adhesives to harden rapidly.
You DO NOT want to use activator with PB002, and very sparingly with thinner adhesives, as it can cause the adhesive to cure too rapidly, exotherm, bubble and turn white. This is a mess you DON’T want. Remember, the cure starts from the outside in. The surface may be hard, but the adhesive is still curing underneath.
Full cure in most adhesives is 24 hours.
NOTE: As PB303 is flammable, it can only be shipped by ground within the continental U.S. and Canada. This item may NOT ship air or international. It cannot be shipped USPS.
WARNING: The chemistry of the activators WILL often turn some fossils green in color (if the fossil is preserved in clay or sand). REMOVING the green color can be accomplished by using water based laundry bleach like Hylex (sodium hyperclorite). Paint on the bleach and allow to sit. Then wash off with pure water.
