- Product Highlights
- This completely variable system can be tailored to meet any application requirement just by varying the mix ratio of resin to hardener resulting in the exact degree of flexibility required for any application.
- It’s easy to use. Just dispense resin and hardener, mix to a uniform color and apply.
- Adheres to most plastics, metals, ceramics, glass, rubber and even Teflon™(treated).
- Cures at room temperature for use from -100°F to +450°F and will not soften or gum up at high temperatures.
- Duralco 4538 offers excellent chemical resistance and high bond and peel strength.
- It is ideal for all electric and electronics applications and can be used with most common chemicals and solvents.

- Adjusting the Flexibility
Just pick the degree of flexibility desired. Then select the resin to hardener ratio from the table.
- Use formulation "A" for applications where additional rigidity is required.
- Use formulation "B" for most applications.
- Use formulation "C" or "D" for severe thermal shock, vibration or bonding of dissimilar materials that re- quire additional flexibility.
