West System 205 Standard Hardener

 There are four WEST SYSTEM hardeners, three to provide working times for almost every kind of project and one for coating where an extra special finish is required. It is essential that the resin and hardener are mixed in the correct ratio. These ratios ensure that a complete chemical reaction occurs which results in optimal performance. The easiest way to achieve the correct ratio, time and time again, is through use of the correct dispensing pumps.

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. Where a slower curing time is required, 206 hardener is recommended. 205 Hardener must be mixed in the correct ratio of 5 parts by weight of 105 Resin to 1 part by weight of 205 Hardener. Weight: 0.2kg.

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
Pumps Required (5:1 ratio): 301, 306, 309 

205 Hardener must be mixed in the correct ratio of 5 parts by weight of 105 Resin to 1 part by weight of 205 Hardener.

WEST SYSTEM Brand epoxy is a versatile, high-quality, two-part epoxy that is easily modified for a wide range of coating and adhesive applications. It is used for construction and repairs requiring superior moisture resistance and high strength. Originally developed by Gougeon Brothers Inc. over 35 years ago for the production of wooden boats, WEST SYSTEM epoxy products are now recognised throughout the marine industry and are in everyday use for the repair and construction of fibreglass, wood, aluminium, steel, composite and ferrocement vessels. The knowledge that the WEST SYSTEM epoxy is designed for the marine environment - a particularly harsh and demanding requirement - promotes enormous confidence in the product range and, in more recent years, WEST SYSTEM epoxy has been used extensively in the construction industry, model making and the DIY market for many applications.
