Description
The liquid formula catalyst for Tenax polyester stone adhesives. Tenax Hardener Liquid (50ml / 2 oz) activates and cures Tenax polyester-based adhesive systems. The liquid formula differs from the Extra White Paste hardeners — verify compatibility with your specific adhesive before use, as some Tenax polyester systems specify paste hardener only.
For the Extra White Paste hardener used with Colored Knife Grade Polyester and Tixo Xe, see the 45ml, 118ml, or 180ml paste sizes.
Key Features
- Liquid formula — alternative to the Extra White Paste hardener; verify compatibility with your adhesive system before use
- 50ml / 2 oz — compact size for small batch mixing and field use
- For Tenax polyester adhesive systems — activates and cures polyester-based stone adhesives
- 6-month shelf life — stored between 65°F–77°F away from heat and direct sunlight
How to Use
- Add hardener to the adhesive at the recommended mix ratio — refer to your adhesive's technical data sheet for the correct ratio
- Mix thoroughly until color and consistency are completely uniform
- Do not exceed the recommended hardener ratio — excess hardener causes yellowing and increased shrinkage
- Apply immediately after mixing; pot life is limited once hardener is introduced
