Technical Product Bulletin
RIGID STAKING COMPOUND EPOXY ADHESIVE
PRODUCT DESCRIPTION
Stone-Bond 24 is a two part, heat-resistant and low exotherm, epoxy adhesive formulation. It is a 100% solid epoxy adhesive, with superior chemical resistance and shear strength.
Stone-Bond 24 contains a thixotrophic agent which impedes thinning out of the material during heat cure when properly mixed and cured.
The formulation provides a tough enamel-like cure that bonds effectively to a variety of substrates while maintaining weather resistance for long-term durability.

GENERAL INFORMATION
For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).
HOW TO USE
- Carefully clean and dry all surfaces to be bonded.
- Apply Stone-Bond completely mixed adhesive to the prepared surfaces, and gently press these surfaces together. Contact pressure is adequate for strong, reliable bonds; however, maintain contact until adhesive is completely cured.
- Some separation of components is common during shipping and storage. For this reason, it is recommended that the contents of the shipping container be thoroughly mixed prior to use.
- Some ingredients in this formulation provided may crystallize when subjected to low temperature storage. A gentle warming cycle of 52°C for 30 minutes prior to mixing components may be necessary. Crystallized epoxy components do not react as well as liquid components and should be re-dissolved prior to use for best results.
- Allow the product to cure according to the cure schedule for optimal performance.
