## Description

West System 105-B Epoxy Resin Bundle with 206-B Slow Epoxy Hardener and 300 Mini Pumps Epoxy Metering Pump Set, Pale Yellow: desertcart.com: Industrial & Scientific

## Features

- CONVENIENT EPOXY BUNDLE contains one can of WEST SYSTEM 105-B Resin (126.6 fl oz), WEST SYSTEM 206-B Slow Hardener (27.5 fl oz), and one set of calibrated 300 Mini Pumps. 206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working time or a longer cure time is needed. It also provides adequate working time at higher shop temperatures.
- 105 EPOXY RESIN is a clear, pale yellow, low-viscosity liquid epoxy resin. Blended with 206 Slow Hardener at a 5:1 ratio, it cures to a hard, solid plastic with superior physical properties. It will wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals. (206 Slow Hardener is not intended for clear coating.)
- POT LIFE AT 72°F (22°C) is 20 to 25 minutes. Cures to a solid state in 10 to 15 hours. Cures to maximum strength in 1 to 4 days. Minimum recommended working temperature is 60°F (16°C). Does not contain VOCs and has relatively high flash point and no solvent odor, making it much friendlier to use than styrenated resins.
- EXCELLENT FOR COATNG OR BONDING, this epoxy is easily modified with WEST SYSTEM fillers, pigments, and additives to suit an enormous variety of construction and repair projects, including fiberglass boat repair, strip kayak and canoe construction. Resin viscosity is approximately 1000 centipoise at 72°F (22°C)
- INCLUDES CALIBRATED PUMPS that dispense 105 Resin & 206 Slow Hardener at the correct 5-part resin to 1-part hardener mix ratio. One pump stroke of resin for each one pump stroke of hardener yields 0.8 fl oz of the exact 5:1 epoxy mix ratio. These durable polypropylene pumps provide years of dependable service.

## Questions & Answers

**Q: Does this dry clear?  If not what color does it dry?**
A: The 206 hardener drys almost clear, is has a very little touch of Amber.

West Systems has a "Clear" it is the 207 hardener. Unless you are using a blonde wood I seriously doubt you will notice the 206 slight coloring. 

Enjoy your project and always push the boundaries!

**Q: what is the pot life of this product**
A: It depends a lot on the outside temperature and how large a pot you mix up.  You want to use this slow hardener on large layups or during the summer heat.  You use it in winter, and it can take a a long time to harden.  Rough guess, I'd say you have a half-hour in summer and an hour or more in winter.

**Q: Why are there three pumps instead of two?**
A: One pump in slow hardener 206b one is for regular hardener 207 and the other is for  105b epoxy resin 105b

**Q: what is the pot life of this product**
A: I have been getting about 1 hour in an 80 degree environment in a very small batch (1-2 pumps).   It cannot be used at temps below 60 degrees. It is exothermic: large batches get hot and will cure much faster.
