| SPECIAL RECOMMENDATIONS |
|---|
| Special Recommendations | Mixing ratio 100 parts AV138 to 40 parts HV998 by weight. · The material is available in thicknesses of 12, 25, 50, 75 and 125 microns. · Sensitivity to water absorption by the catalyst before use. This may degrade outgassing and mechanical properties. · Does not pass odour test with cure at RT; passes with cure at 65°C. · Recommended cure time: 48 hours at room temperature. · AV138M is newer version of AV138 |
