Not intended for clear coating. 206 B size hardener is matched for use with 105 B size resin. Review: STRONG STUFF - MUCH BETTER THAN POLYESTER RESIN Review: Poor shipping for great product - These resins always work quite well and it seemed convenient to order through desertcart versus picking it up at West Marine as usual. The packaging was so flimsy and they're lucky the resin can didn't break and spill all over their delivery vehicle as it was quite crushed. I was able to bend it back into shape and make it useful, but a little diligence in packaging would have been nice. ## Features - The 105 Epoxy Resin (105-B) is the base material on which all WEST SYSTEM 105 System epoxy compounds are built. It has excellent structural bonding properties when combined with the 206 Slow Hardener (206-B) at a 5:1 ratio. - The 206 Slow Hardener (206-B) is useful when extended working time and cure time is needed. It produces a slow cure that develops full strength at room temperature over 1-4 days. - This bundle is easily modified with WEST SYSTEM fillers, additives and pigments to suit coating, fiberglass, structural bonding or fairing projects. - The cured 105/206 epoxy is a high-strength, rigid, moisture and vapor resistant solid with a working time of 20-25 minutes at 72°F when mixed. - This epoxy cures at temperatures as low as 60°F and will cure faster at warmer temperatures for flexibility based on your project needs. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C3MY967W | | Brand | West System | | Brand Name | West System | | Color | clear | | Compatible Material | Fiberglass, Paper, Wood | | Container Type | Can | | Customer Reviews | 5.0 out of 5 stars 11 Reviews | | Full Cure Time | 4 Days | | Item Form | Liquid | | Item Package Quantity | 1 | | Manufacturer | West System | | Material | Epoxy Resin , Resin | | Material Type | Epoxy Resin, Resin | | Model | 8dad8ea9-a6b4-4a81-a915-2de7bd4ca0db | | Other Special Features of the Product | Wide temperature cure range, self-leveling, high-strength, moisture-resistant | | Special Feature | Wide temperature cure range, self-leveling, high-strength, moisture-resistant | | Specific Uses For Product | Woodworking, Repair, Flooring, Masonry, Countertop | | Unit Count | 1.0 Count | | Viscosity Level | Low to Medium | | Volume | 4 Fluid Ounces | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** West System - **Color:** clear - **Item Form:** Liquid - **Material:** Epoxy Resin, Resin - **Special Feature:** Wide temperature cure range, self-leveling, high-strength, moisture-resistant ## Images ![- West System 105-B Epoxy Resin and 206-B Slow Hardener - Image 1](https://m.media-amazon.com/images/I/61xO6reCnHL.jpg) ![- West System 105-B Epoxy Resin and 206-B Slow Hardener - Image 2](https://m.media-amazon.com/images/I/61slwaQ3KUL.jpg) ![- West System 105-B Epoxy Resin and 206-B Slow Hardener - Image 3](https://m.media-amazon.com/images/I/81ZnL4CXwaL.jpg) ![- West System 105-B Epoxy Resin and 206-B Slow Hardener - Image 4](https://m.media-amazon.com/images/I/817fw5Ge1aL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ STRONG STUFF *by B***L on November 4, 2025* MUCH BETTER THAN POLYESTER RESIN ### ⭐⭐⭐⭐⭐ Poor shipping for great product *by O***S on October 30, 2023* These resins always work quite well and it seemed convenient to order through Amazon versus picking it up at West Marine as usual.
