WEST SYSTEM #205, FAST HARDENER-GROUP SIZE "B"

Description

205 Fast Hardener is a medium-viscosity epoxy curing agent. It is useful in a majority of bonding situations, and at lower temperatures. 205 Fast Hardener produces a rapid epoxy cure that develops physical properties quickly at room temperature. Mix it with WEST SYSTEM 105 Resin in a five-part resin to one-part hardener ratio. The resulting cured epoxy is a rigid, high-strength, moisture-resistant solid. The combination of 105 Resin/205 Fast Hardener has excellent bonding and coating properties. 205 Fast Hardener is not intended for clear coating. Pot Life at 72F (22C): 9 to 12 minutes Cures to a solid state: 6 to 8 hours Cures to maximum strength: 1 to 4 days Minimum recommended temperature: 40°F (4°C) Mix Ratio: 5 parts resin : 1 part hardener Pumps required: (5:1 ratio) 300, 306 or 309 Volume: .86qt(.81L). (mixed resin and hardener volume=1.2GAL/4.55L) COATING COVERAGE: 205-B or 206-B Saturation coat porous surfaces: 350–405 sq.ft. (32–37 SQM) Buildup coats non-porous surfaces: 462–520 sq.ft.
