Why Starbond EM-150?
EM-150 delivers a unique oil-like feel and 150 cPs viscosity that allows it to:
- Penetrate narrow slots up to 0.006" while still filling small gaps
- Cure naturally in 10–20 seconds (no accelerator required)
- Bond wood, metal, ceramics, stone, fiberglass, carbon fiber, rubber, leather, and most plastics
Key Features & Benefits
Woodturning & Finishing
Use EM-150 to achieve high-gloss CA finishes on pens, bowls, and knife handles. It fills hairline cracks, knots and voids for a flawless finish that sands and polishes beautifully.
Lapidary & Stone Repair
Trusted by professionals to stabilize cracked gemstones, create a durable high-gloss polish on petrified wood, and repair marble, granite, and quartz.
Hobbyists & Model Builders
Perfect for assembling models, bonding balsa and lightweight materials, and securing RC tires. Typical no-accelerator cure is 10–20 seconds for quick assembly.
Multi-Material Bonding
Works across a wide range of substrates — from metals to plastics to composites — making EM-150 a go-to shop adhesive.

Frequently Asked Questions
- What is the shelf life of this CA Super Glue?
- When stored correctly under 40°F (4°C) — for example, in a refrigerator or other cold environment — Starbond EM-150 can maintain superior performance for up to 30 months.
- Is an accelerator spray required for use?
- No. EM-150 cures naturally within 10–20 seconds. An accelerator is optional and recommended only when working with very porous substrates or when an instant cure is required.
- What materials is this medium CA glue compatible with?
- EM-150 bonds effectively to wood, metal, ceramics, rubber, leather, carbon fiber, fiberglass, and most plastics. Always test on non-critical pieces when working with unknown plastics or painted/coated surfaces.
Tips for Best Results
- Prepare surfaces by cleaning and degreasing. Slight sanding improves mechanical bite on smooth substrates.
- Use sparing amounts — CA glues bond by surface contact; excessive glue can weaken the joint or increase cure time.
- For porous materials, consider a short burst of accelerator to reduce soak-in and speed full strength development.
- Store sealed bottles in a cool environment; follow manufacturer recommendations for long-term storage.
