Permabond offers several toughened grades of ceramic bonding adhesives. Ceramic materials are inorganic compounds that are typically rigid and very brittle. They are generally electrically non-conductive and have good heat resistance and resistance to harsh chemicals. The brittleness of ceramics often calls for toughened grades of adhesive which can resist the different thermal expansion rates between the ceramic and adjoining substrate.
Structural one-component epoxy and two-component epoxy adhesives are good options. Similarly, toughened acrylic adhesives provide good strength – but opt for a 1:1 system over the resin/initiator products. For food-grade ceramic applications, Permabond food-grade epoxy ET5145 is recommended.
PERMABOND® ET5145 is a 1:1 mixable epoxy adhesive. It has excellent resistance to impact and vibration and is ideal for structural bonding of metal, wood, composites, ceramic, and certain plastics. ET5145 is high-strength and has excellent environmental durability. It is suitable for applications where cured products come into contact with food or beverages.
Permabond ET5145 has been specifically formulated to meet the requirements of: FDA 175.105 and 175.300.
1. Remove glaze by abrasion or grit-blasting.
2. Then remove loose particles with acetone, isopropanol, or Permabond Cleaner A.
3. Ensure the solvent has fully evaporated before applying adhesive (solvent may remain trapped in pores).
