This resin is a clear, light-amber, low-viscosity epoxy, which, when mixed with one of the WEST SYSTEM hardeners, is formulated to wet out wood fibre, fibreglass and a variety of metals.
When mixed with the appropriate hardener, it is an excellent adhesive, which will fill gaps and bridges voids when modified with WEST SYSTEM fillers and can be sanded and shaped when cured. With roller applications, it possesses excellent thin-film characteristics by flowing out and self-levelling without any fisheyeing. The epoxy mix cures to a clear finish so that a natural finish may be achieved by coating with a good quality two pack polyurethane varnish.
Dispensing pump 301 A is advised for accurate measuring. Please note the pump sets are already calibrated so you only need 1 pump of resin to 1 pump of hardener to get the 5:1 ratio.
Which pack do I use?
205 Hardener is used in a majority of situations to produce a rapid cure and results in an epoxy which develops its physical properties quickly. When mixed with 105 resin, the cured system yields a high-strength, rigid solid which has excellent cohesive properties and provides an outstanding moisture vapour barrier with excellent bonding and coating properties. 105/205 Pot Life At 25°C 10 to 15 minutes Cure To Solid State At 21°C 5 to 7 hours Cure To Maximum Strength At 21°C. 5 to 7 days Minimum Recommended Temperature 5°C
206 Hardener should be used where ambient temperatures are higher and/or greater working time is required. The resulting mix yields a performance very similar to 205 Hardener.
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
Minimum Recommended Temperature 16°C
The use of the west system pump sets gives you the convenience of a clean dispense and an accurate mix. Prime the pumps as shown on the video (see video tab above) please note that these pumps are ’calibrated’ which means one full pump of 105 to one full pump of 205/206 hardener will give you the automatic ratio of 5 to 1 required.
