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 mm. ·
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. |
