INSTRUCTIONS FOR USING PALEO BOND
STABILIZING AND STRENGTHENING FOSSIL BONE:
The internal and external condition of a fossil bone surface can be a frustrating challenge. Mother Nature kind of ignored the quality of preservation on some of the fossils and we have to try and correct her failings. Paleo Bond Penetrant and Stabilizer (PB-002) just may become your best tool out in the field. It hardens the fragile remains in-situ so you can remove the fossil without further damage. If you have any Pyrite disease, just squirt in the PB-002 to stop any further oxidation.
PRE-PREP CONSOLIDANT (PB4417):
There are times when I wish our original Penetrant and Stabilizer wasn’t so darn strong. If I have gotten dirt on the bone I’m applying stabilizer to, I’ve just bonded the dirt as well; or if I have to realign a damaged area I have to fight with the very strong, tough adhesive. We have made a low strength and fragile penetrating stabilizer that can be mechanically removed with an air scribe or micro sandblaster. Two years of field trials have proven it worthy to join the Paleo Bond family. Just use it in the field in place of PB002 and remove it in the lab before you continue with aligning and repairing your fossil.
REPAIR OF BROKEN BONE TECHNIQUE:
When you are planning to join a bone-to-bone fracture, a careful examination of the break is necessary. Small parts of the broken surface often fall sideways or misalign themselves with the opposing surface, preventing a quality matched surface rejoining.
1. Gently clean the two opposing surfaces with a fine quality brush to remove any loose particles away. Make a test rejoining without using any adhesive. If you have a poor match, dig out the object that is preventing the match and try again. When you are satisfied, make a mark across the joining line with a felt pen or pencil. This will help you keep the alignment after you separate the pieces to apply adhesive.
2. Apply Paleo Bond Penetrant and Stabilizer (PB-002) to both opposing surfaces. Let it soak in until the surface dulls; apply more if the bone will take it. You are strengthening the internal micro-vascular substrate with a structural adhesive.
3. Choose from one of the adhesives (40, 100, 750, 1500 or Jurassic Gel) depending on the error between the two opposing surfaces. Apply to ONE surface; join the opposing surface matching up the line you made previously.
4. WIPE AWAY any excess and squeeze out.
5. HOLD the parts together.
6. If you need a faster bond, SPRAY the Activator 304 sparingly on the bond line. This will give an immediate low strength bond. This bond will gain considerable strength as time passes.
FOSSIL IVORY REPAIR:
We have considerable experience from the paleontology field and the knife making circles that the Penetrant and Stabilizer (PB-002) works wonders. When ivory loses its moisture, it shrinks, hence the cracking. The PB-002 seals and bonds the fine openings and cracks and stabilizes the ivory.
Instructions for Using PB505 Cured Adhesive Remover
PB505 Cured Adhesive Remover works best where there is a thin layer of adhesive. If you are dealing with a thick layer, use an air scriber to remove as much as possible before using PB505.
1. Paint the layer of adhesive with PB505.
2. Apply a couple of layers of paper toweling saturated with PB505.
3. Cover this with aluminum foil to slow down evaporation.
4. Wait several hours while the PB505 dissolves the glue and the paper toweling absorbs the glue via capillary action.
5. If it has sat long enough, you will be able to remove the paper toweling without much trouble.
6. Go to a sink and wash away any residue.
7. Dry completely.
8. Be sure all of the PB505 has been washed away before proceeding with applying any Paleo Bond Adhesives or Penetrant and Stabilizer.
