Zap CA (Thin Viscosity)

The Ultimate Penetrating & Wicking Adhesive

Zap CA is the thinnest cyanoacrylate in the Zap product line, engineered specifically for its incredible penetrating ability. Known as a 'wicking' glue, its low viscosity allows it to travel deep into joints and porous materials that other adhesives simply cannot reach. This unique capillary action has made it a favourite for hobbyists and professionals worldwide.

Why Hobbyists & Makers Choose Zap CA:

• Unmatched Penetration: Easily wicks into tight-fitting joints and pre-assembled parts.
• Instant Bonding: On materials like balsa wood, it bonds almost instantaneously, often travelling several inches into the grain for a deep, structural hold.
• Consistent Performance: Unlike budget brands, Zap CA offers a reliable, high-strength bond that resists brittleness over time.

Targeted Applications

RC & Scale Modelling

The perfect adhesive for lightweight balsa wood construction. Because it is so thin, you can dry-fit your wing ribs or fuselage parts and simply drop the glue onto the joint; it will pull itself into the wood for a permanent bond. It is also ideal for tack-welding parts in place before applying a secondary fillet of Zap-A-Gap.

Woodworking & Woodturning

A staple on the workbench of cabinet manufacturers and woodturners alike. Use Zap CA to stabilise cracks or knots in wood by mixing it with sawdust to create a seamless filler. Turners frequently use this thin formula as a high-gloss, durable finish for pens and small turned projects.

Jewellery & Dental Labs

In jewellery manufacturing, it is the go-to for securing accents and stones in tight-fitting settings. In dental labs, its quick cure and precision make it ideal for adhering pins into models and securing articulators to bases.

Pro-Tips for Best Results

• Preparation is Key: Since this glue wicks into joints, ensure your parts are perfectly aligned before applying the adhesive. You will only have a second or two before it sets.
• Clean Application: Use a fine-point applicator tip to prevent over-runs. Because it is as thin as water, it can run quickly if too much is applied at once.
• The Sawdust Trick: To fill a crack in timber, pack the area with fine sanding dust and drop Zap CA onto it. It will soak through the dust and harden into a sandable, permanent repair.
