West System Epoxy 206 Slow Curing Hardener 0.2kg

• West System 206 slow hardener can be used for extended assembly times when working in ideal conditions or the ambient temperature is higher than normal.
• When mixed with 105 Resin the cured mixture yields a high-strength, rigid solid which has excellent cohesive properties and provides an outstanding moisture vapour barrier with excellent bonding & coating properties.
• 206 Epoxy Hardener is used for general coating and bonding applications when extended working and cure time are needed or to provide adequate working time at higher temperatures.

105/206 Epoxy forms a high-strength, moisture-resistant solid with excellent bonding and barrier coating properties. It will wet out and bond to wood fibre, fibreglass, reinforcing fabrics, foam and other composite materials, plus a variety of metals. 105/206 Epoxy can be thickened with WEST SYSTEM fillers to bridge gaps and fill voids. Once cured it can be sanded and shaped.

With roller applications, it has excellent thinfilm characteristics, allowing it to flow out and self-level without fish-eyeing. Multiple coats of 105/206 Epoxy create a superior moisture barrier and a tough, stable base for paints and varnishes.

It is formulated without volatile solvents resulting in a very low VOC content. It has a relatively high flash point, no strong solvent odour and does not shrink after curing. It is not intended for clear coating natural finished wood.
