The kit combines a large can of clear pale yellow 105-B resin, a can of 206-B slow hardener and calibrated 300 mini pumps that deliver the correct 5:1 mix ratio, which makes it especially useful for boatbuilding, canoe and kayak construction, and structural bonding where consistent mixes and longer pot life matter.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete bundle:\u003c\/strong\u003e Includes a 126.6 fl oz can of 105-B resin, a 27.5 fl oz can of 206-B slow hardener and a set of calibrated 300 mini pumps so users have all basic components for many projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccurate pump metering:\u003c\/strong\u003e The calibrated mini pumps dispense resin and hardener at the 5:1 ratio, so one stroke of each produces the exact 5:1 mix and reduces guesswork when measuring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended working time:\u003c\/strong\u003e 206-B slow hardener is low viscosity and formulated for longer pot life and better working time at higher shop temperatures, helpful during laminating or large fills.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGood wetting and bonding:\u003c\/strong\u003e The 105 epoxy resin wets out wood fibers, fiberglass and reinforcing fabrics and bonds to many metals, making it versatile for repairs and construction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow odor and safer handling:\u003c\/strong\u003e The system contains no VOCs and has a relatively high flash point and no solvent odor, making it friendlier in small shops compared with styrenated resins.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe bundle is best for hobbyists, woodworkers and small boatbuilders who need a proven, adaptable epoxy system with accurate metering and a slower hardener for working on larger areas or in warm conditions. The included pumps make it a good choice for users who prefer pump dispensing over weighing or mixing by volume.\u003c\/p\u003e\n\u003cp\u003eThose who need a clear high-gloss finish for appearance reasons should note that the 206-B slow hardener is not intended for clear coating applications; finish-focused users may prefer a different hardener for topcoats.
