Pot life: 3 - 5 mts. @ 25 °C tor Ark 1241, Ark 1242, Ark 1244, Ark 1256 and Ark 1255
Pot life: 10 - 15 mts. @ 25 °C tor Ark 1258, Ark 1245, Ark 1243 and Ark 1246 - Ark 1241 is designed for rapid cure but very short pot life and hence modified with other curing agents to extend pot life for primer / flooring applications
- Ark 1241 may have better flexibility than Ark 1242
- Ark 1242 is ideal for crack repairs in marbels
- Ark 1244, Ark 1241. Ark 1242, Ark 1243 and Ark 1258 are good chemical resistant
- Ark 1244 is very rapid cure and may be used as adhesive but not flexible as Ark 1255 and Ark 1245
- Ark 1244 may perform better chemical resistance and may replace mercaptans
- Ark 1246 may be used as adhesive with excellent flexibility, adhesion and faster curing with adequate pot life and designed for equal mixing ratio with GY 250 type epoxy resin
- Ark 1255 and Ark 1245 are designed tor putty applications
