105 resin mixed with 206 slow hardener can be used for extended assembly times when working in ideal conditions or the ambient temperature is higher than normal. WEST SYSTEM 105-206 cured resin/hardener mixture yields a high-strength, rigid solid which has excellent cohesive properties and provides an outstanding moisture vapour barrier with excellent bonding & coating properties.
WEST SYSTEM 105-206 Pot Life at 25°C = 20 to 30 minutes Cure to Solid State at 21°C = 9 to 12 hours Cure to Maximum Strength at 21°C = 5 to 7 days.
