Product Description

Slo-Zap CA (High Viscosity)

The Ultimate Gap-Filler with Extended Working Time

Slo-Zap is the thickest cyanoacrylate in the Zap range. With a consistency similar to honey or maple syrup, it is engineered for applications where speed is less important than precision and strength. Because it does not wick into porous materials, it stays exactly where you put it, making it the superior choice for imperfect joints and structural bonding.

Why Hobbyists & Makers Choose Slo-Zap:

• Maximum Gap Filling: Ideally suited for loose-fitting joints, cracks, and seams where a thinner glue would simply run off.
• Extended Positioning Time: Offers those crucial extra seconds to align parts perfectly before the bond sets.
• High Structural Strength: Once cured, Slo-Zap provides an incredibly hard and durable bond, making it the preferred choice for high-stress areas.

Targeted Applications

RC & Scale Modelling

Ideal for laminating large wood sections and bonding fibreglass or fabric to substrates. Because it is thick, it will not over-saturate cloth, allowing you to spread it evenly to fill the weave. Use it with a Z-End tip to create structural fillets around motor mounts or landing gear blocks.

Woodworking & Furniture Repair

A lifesaver for furniture restoration. It is perfect for repairing loose chair rungs, mortise and tenon joints, or filling larger cracks in woodturning projects. Pattern makers and mould shops rely on Slo-Zap to fill seams and create a sandable, rock-hard surface.

Pro-Tips for Maximum Bond Strength

• Clamping is Key: Unlike thinner CAs, Slo-Zap performs best with light to medium clamping pressure while it cures naturally.
• Strategic Accelerator Use: To get the best of both worlds, spray Zip Kicker on one part and apply Slo-Zap to the other. You will still have a few seconds to reposition the joint before it locks in place.
• Spreading: When working with large surface areas or fibreglass cloth, use a soft plastic spreader or an old business card to create an even, thin film of adhesive.
