Adhesive FAQ

Our epoxy adhesives will form tenacious bonds to wood, metal, composites, concrete, masonry, glass, rubber, and thermoset resins like Epoxy, Polyester, and Polyurethanes. Epoxies, in general, will form poor bonds to thermoplastics like ABS, PVC, Polyethylene, and Acrylic.

To ensure a good bond, at a very minimum, the surfaces to be bonded should be clean, sanded (no finer than 150 grit), and solvent wiped.

Some materials will benefit from further preparation to achieve maximum performance. Linked below are articles that describe optimal surface prep for common materials.

System Three offers a variety of epoxy adhesives that are formulated to meet a wide range of applications.

Structural Adhesives: High Performance, waterproof adhesives that can be considered for load bearing construction and repairs.

• T-88: Our comprehensive structural adhesive that stands up to adverse application and service conditions. T-88 is the perfect choice as your on-hand epoxy adhesive to keep in the shop or truck.

• G-2: Excels in woodworking applications. G-2’s long, no-rush working time makes it an excellent choice for fine joinery and furniture making. G-2 is a great choice for bonding oily woods like teak and other tropical woods.

• GelMagic: A toughened, non-sagging, gap filling adhesive that has a consistency similar to Vaseline. It forms a permanent bond that is highly impact and fracture resistant. GelMagic can withstand elevated service temperatures and can be post cured for improved properties.

• Blade Pro: A two-component, high-performance glue designed specifically for the knife maker. This state-of-the-art adhesive forms super tough, flexible bonds to wood, Micarta, G10, and other composites. Tenacious bonds are developed to non-ferrous metals, as well as stainless and carbon steel. Blade Pro can also be used as a high-performance adhesive for many other applications where a low viscosity glue is preferred.

• Metlweld: Forms a permanent, non-brittle bond with high impact and creep resistance. Metlweld will bond tenaciously to most metals including mild steel, stainless steel, aluminum, and copper alloys. It also bonds to glass, stone, concrete, and masonry. It's our epoxy of choice for bonding dissimilar materials.

Hobbyist Adhesives: Quick setting water resistant epoxy adhesives designed to form a strong bond rapidly. Not rated for load bearing repairs and construction.

• Quick Cure 5 and 15: Are excellent choices when you need a good, strong glue that will bond two materials together in minutes. Use to quickly seal edges and cracks, or fill small knot and screw holes.

When exposed to exterior conditions there are a few factors that you need to account for before choosing an adhesive, particularly when gluing wood components together. Check out our article Using Epoxy Adhesive for Outdoor Wood to see if your outdoor project is suited for an epoxy adhesive.

Liquid epoxy resin-based products, if they have gotten too cold or too old, may crystallize, harden, and turn white in the container. System Three® two-part products are formulated to resist crystallization, but it can still occur. Crystallization does not damage the resin in any way and resins are typically recovered in one of two ways:

1) Heating in a water bath at 125°F or above until the resin clears up.

2) Heating in a microwave 10 seconds at a time until the resin clears up.

Make sure the crystals or cloudiness is completely gone, or the product can recrystallize in a short period. Allow the resin to return to room temperature before use.

NOTE: Hardeners (curing agents or Part B) will not crystallize but may darken over time. This color change will not affect their performance.
