Product: West System 105B Epoxy Resin (126.6 fl oz) Bundle with 207SB Special Clear Epoxy Hardener (42.2 fl oz) and 300 Mini Pumps Epoxy Metering 3-Pack Pump Set (3 Items)

This 105B Epoxy Resin is the base material on which all West System 105 System epoxy compounds are built. It is a clear, pale yellow, low-viscosity liquid epoxy resin. Blended with hardener at the proper ratio, it cures to a hard, solid plastic with superior physical properties. Based on which hardener you choose, it cures at a wide range of temperatures. Once cured, it forms a high-strength solid that is functionally waterproof, and highly resistant to moisture. The West System 105B Epoxy Resin is designed to wet out and bond with wood fiber, fiberglass, and reinforcing fabrics. It also bonds well with a variety of metals when mixed at the proper ratio with a West System Epoxy hardener.

No Strong Solvent Odor

105 Epoxy Resin is formulated without volatile solvents and does not shrink after curing. It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyester or vinylester resins. Resin viscosity is approximately 1000 centipoise (cP) at 72-degree-F.

Thickening Epoxy

Modifying this epoxy with West System fillers creates an excellent structural adhesive or fairing compound. You choose the filler that suits your project. Epoxy thickened with adhesive (high-density) fillers makes structural bonds, bridges gaps, and fills voids. Epoxy thickened with fairing (low-density) fillers is easily sanded and shaped after it cures.

WEST SYSTEM EPOXY: Based on 105 Epoxy Resin, West System Epoxy is a versatile low-viscosity epoxy system. It is used for boat building, composite construction and repairs that require high-strength, waterproof coating, bonding, and filling. It readily wets out fabrics and porous materials, and is easily modified for a wide range of working conditions and applications
NO STRONG SOLVENT ODOR: 105 Epoxy Resin is formulated without volatile solvents and does not shrink after curing. It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyester or vinylester resins. Resin viscosity is approximately 1000 centipoise (cP) at 72-degree-F (22-degree-C)
STRONG PHYSICAL PROPERTIES: The 105/207 Epoxy Mixture has strong physical properties, so it can be used as a structural adhesive for gluing and laminating. It has excellent compatibility with paints and varnishes. An ultraviolet inhibitor in 207 Special Clear Hardener helps provide a beautiful, long-lasting finish when used with quality UV filtering varnish. The 105/207 Epoxy Mixture cures clear and colorless
APPLICATIONS: Three coats or more can be applied in one day without additional surface preparation. Fewer coats are required to fill fiberglass weave and in most cases, the final coating can be sanded the following day. Builders also appreciate the excellent fiberglass wet-out characteristics achieved with 105 Resin/207 Special Clear Hardener Mixture, yet it won’t drain from vertical surfaces like the very slow curing, low-viscosity epoxies West System
