Product Name
Devcon Flexane 94 Liquid Castable, non-shrinking, low-viscosity urethane compound
Brief Description
Devcon Flexane 94 Liquid is a two-part, low-viscosity, non-shrinking urethane compound that cures at room temperature to a rigid, rubber-like material with a Shore A hardness of 97. It is designed for a broad range of repairs, tooling, and molding applications requiring a tough, flexible material.
Popular Applications & Uses
- Reproducing low-to-medium-volume or discontinued rubber parts- Forming flexible molds and non-scratching holding fixtures/linings- Encapsulating wire and electronics subject to impact, vibration, expansion, and contraction- Pads for press brake forming- Lining process equipment to dampen noise- Protecting equipment surfaces from wear and corrosion- Pouring concrete expansion joints- Casting flexible parts and molds
Industries that Commonly Use It
- General Manufacturing- Mold Making/ Casting- Automotive Service/Repair- Construction/ Building Services- Metal Fabrication- Electrical Services or Products- Industrial Supply- Aerospace/Defense- Government & Military (indicated by NSN stock number)- Engineering Services- Fabrication
Special and Unique Features
- Room temperature curing, no heat required- Mixes and pours easily- Low viscosity (6,000 cps)- Non-shrinking (cured shrinkage 0.0014 in./in. or 0.0004 cm/cm)- 5-hour demolding time- Cures to a rigid rubber material (Hardness Shore A 97)- Excellent tear strength and abrasion resistance

(ASTM D2566) or 0.0004 cm/cm- **Pot Life:** 10 minutes @ 75°F (25°C)- **Demolding Time:** 5-10 hours- **Functional Cure:** 16-24 hours- **Full Cure:** 7 days @ 70°F (21°C)- **Tensile Strength:** 6,000 psi or 27.6 N/mm² (ASTM D1002)- **Tear Resistance:** 415 pli or 19 N/mm² (ASTM D624)- **Dielectric Strength:** 350 Volts/mils (ASTM D149) or 14 KV/mm- **Color:** Black- **Temperature Resistance:** Wet 49°C, Dry 82°C
Surface Compatibility
Devcon Flexane 94 Liquid bonds effectively to a variety of substrates, including:- Metal surfaces (requires Devcon FL-10 Primer)- Rubber and Urethane surfaces (requires Devcon FL-20 Primer)- Concrete surfaces (requires Devcon FL-20 Primer, multiple coats may be needed for porous concrete)- Wood (requires Devcon FL-20 Primer)- Fiberglass (requires Devcon FL-20 Primer)- Rigid Plastics (requires Devcon FL-20 Primer, 2 coats)Proper surface preparation, including cleaning, roughening (grinding or abrasive disc), and sandblasting for maximum adhesion, is crucial.
Known backups / known substitutes
- **Devcon Flexane 60 Liquid:** A more flexible urethane with a Shore A 65 hardness.- **Devcon Flexane 80 Liquid:** A medium flexibility urethane with a Shore A 87 hardness.- Other liquid plastic casting resins or urethane casting compounds from manufacturers like Smooth-On, Inc. or Curbell Plastics, offering various rigid or semi-rigid properties for similar applications.
Comparison Note
Devcon Flexane 94 Liquid is a more rigid material compared to Devcon Flexane 80 Liquid and Flexane 60 Liquid. With a Shore A 97 hardness, it is designed for applications demanding a tougher, more rigid rubber-like material, while still offering flexibility and excellent abrasion resistance.
