Wapsi Head Cement Water Based

Wapsi Head Cement Water Based provides a thin, penetrative bond ideal for tying heads on standard dry flies or nymphs. The water-based formula is non-flammable, ready to use, and can be thinned with water. It dries fully overnight and remains water-stable after curing, with a finish that remains non-sparkly unless multiple thin coats are applied. Suitable for those who prefer a less glossy head and a reliable seal on delicate thread wraps.
Wapsi Fly Head Cement (Flex-Seal)

Wapsi’s Flex-Seal option emphasizes a flexible, yet durable, head cement that yields solid layers when applied in thin coats. It penetrates deeply into thread and materials for a robust bond, while remaining non-flammable and easy to use. This cement works well for building up layers to avoid a shiny finish unless you apply several light coats. It is compatible with both standard dry flies and streamer heads where a glossy buildup is desired with multiple passes.
EUPHENG Fly Tying UV Resin Three Formula

Eupheng’s three-formula UV resin caters to a wide range of tying needs. The thick formula builds up larger heads on streamers and nymphs, while the thin formula is ideal for detailed work on small bodies, wings, and heads. The resin cures in seconds under UV light, delivering a crystal-clear, tack-free finish that remains durable over time. The three-formula setup provides flexibility for both bulk shaping and fine-detail work on various fly patterns.
Eupheng Fly Tying UV Resin Three Formula (Second Listing)

The second Eupheng listing reiterates the three-formula concept, emphasizing a crystal-clear finish and quick cure. This option is suitable for builders who want both a thick option for bulk heads and a thin option for precision work, maintaining a tack-free surface after curing and ensuring long-lasting results on a variety of patterns.
Riverruns UV Clear Glue Three Formula

Riverruns offers a trio of UV glues designed for fast curing and crystal-clear finishes. The thick formula is effective for creating larger heads and coating larger surfaces, while the thin formula penetrates into small areas like bodies and wings. The glues cure in seconds under UV light and are marketed as tack-free after curing, making them a practical choice for high-speed tying workflows and durable, weather-resistant finished heads.
EUPHENG UV Clear Glue Thick Formula

The Thick Formula from Eupheng is geared toward bulk shaping of heads on larger flies, offering stable, non-running coverage that remains crystal clear once cured. This option complements the thinner formulas for precision work, enabling a spectrum of build possibilities—from crisp, compact heads to larger, bulbed profiles. UV curing provides rapid handling times and durable performance in varied fishing conditions.
Buying Guide
- Viscosity and head shape: Choose a water-based, thin cement for fine thread sealing and a UV resin with thick formula for bulk heads. For pressurized patterns, combining thin and thick options helps control build and finish.
- Drying and curing: Water-based cements dry slowly and can be submerged without dissolving once cured; UV resins cure in seconds with a UV light and remain tack-free. Consider your tying pace and whether you have reliable UV lighting.
- Finish and gloss: If you prefer a non-glossy head, apply multiple very thin coats. For glossy, smooth heads, a thicker coat or resin can be built up, followed by light curing to avoid runs.
- Material compatibility: Ensure the cement works with your thread type, feathering, and body materials. Some cements penetrate deeply, while UV resins sit on top and sculpt a head shape.
- Durability and water resistance: Cured products should resist water exposure and maintain rigidity over time. UV resins generally offer superior durability and clarity, while water-based cements provide flexibility and ease of use.
- Safety and handling: Water-based cements are typically safer and less odorous; UV resins require proper protection from UV exposure and careful handling to avoid premature curing.
- Application technique: Build thin layers with careful control to prevent pooling. UV resins demand a consistent light source for uniform curing and a clean workspace to avoid dust.
- Price and availability: Consider bundles or multi-packs that cover both thin and thick formulas to cover diverse flies, balancing cost with versatility.
