STONE 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 thixotropic agent which impedes thinning out of the material during heat cure when properly mixed and cured.
Used across all industries due to its resilience and odorless properties. This powerful product has strong adhesion to many substrates.

GENERAL INFORMATION
For safe handling information on this product, consult the Safety Data Sheet, (SDS).
HOW TO USE
- Carefully clean and dry all surfaces to be bonded.
- Apply STONE-BOND 24 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.
AVAILABILITY
This epoxy can be supplied in many different packages.
