IS-237 is an epoxy reducer used to improve the spray characteristics and film appearance of epoxy coatings. It is added to the admixed paint only after its initial viscosity has been determined, in the amount needed to reach the desired viscosity; the permissible amount is limited by local VOC regulations.
Specifications and Approvals
- Qualified to: MIL-T-81772 Type II
- Compatible with: MIL-PRF-22750 high solids epoxy coatings, MIL-PRF-23377 high solids epoxy primers
- PPG Aerospace recommends checking the most recent QPLs for updated information
Application
- Condition all materials for 24 hours before mixing at 13–35 °C (55–95 °F); paint components should be at least 13 °C (55 °F)
- Do not exceed one pint per mixed gallon
- Reduction lowers volume solids; multiple coats may be needed to reach the specified dry film thickness, which must be confirmed by measurement
- Do not add to material approaching the end of its pot life
