Bring Ancient Finds Back to Life

Whether you’re piecing together a million-year-old fossil or just want to keep your favorite specimen intact, our PaleoBOND collection has you covered. These professional-grade adhesives and stabilizers are trusted by fossil hunters, museum crews, and passionate collectors alike. From super-thin formulas that seep into tiny cracks to thicker gels for bigger repairs, there’s a solution here for every kind of fossil fix

What Is “CPS” Viscosity?

•      Viscosity measures how thick or runny a liquid is—its resistance to flow.
•      PaleoBOND expresses viscosity in centipoise (cP or cps).
•      For reference, water is about 1 cP at room temperature. 
•      So, higher numbers mean thicker, slower-flowing adhesive.
  

PaleoBOND Adhesives & Their Thickness

From thinest to thickest:

• PB40: ~40 cps — very thin, great for fine cracks or precise application.

• PB100 / PB100X: ~100 cps — medium thickness; strong bonding, cures fast, surface‑insensitive (especially PB100X). 

• PB750: ~750 cps — thicker, fills moderate gaps (~0.05 mm).

• PB1500: ~1,500 cps — even thicker, handles larger gaps (~0.25 mm) but still flows. 

• PB4540 (Jurassic Gel): ~12,000 cps — very thick gel for big gaps or uneven surfaces.

   

Choosing the Right Adhesive

1. Apply Penetrant Stabilizer (PB002) first—it’s very thin (<1 cP), so it soaks into  cracks and stabilizes the piece.  

2. Select a structural adhesive based on the gap or fit:

    • Tight or precise joints: PB40 or PB100(X).

    • Wider gaps or surface mismatch: PB750, PB1500, or Jurassic Gel.

3. If speed is important, you can spray Activator (PB304/303) lightly to  accelerate curing without reducing long-term  bond strength.
