A low-viscosity West System epoxy curing agent formulated for use when an extended working time or longer cure time is required. Furthermore, the epoxy provides adequate working time at higher shop temperatures. When combined with the 105A resin at a 5:1 (epoxy resin to hardener) ratio, the cured/ resin/hardener mixture yields a rigid, high strength, moisture resistant solid with excellent bonding and barrier coating properties. The slow hardener is not intended for clear coating.
Project Uses:
Barrier coating.
Bonding.
Boat repairs.
Fabrication.
Marine.
Specifications:
Pot Life (100g cupful) at 25C: 20-30 minutes.
Working Time (thin film) at 25C: 90-110 minutes.
Solid State at 25C: 9-12 hours.
Cure to maximum strength: 1-4 days.
Minimum recommended temperature: 16C.
Epoxy cures faster at higher temperatures and in thicker applications.
