- German-Engineered, High Quality Spray-On Zinc for Permanent Rust and Cathodic Corrosion Protection
- Manufactured with very high purity zinc flakes for superior protection than sprays made with zinc pellets.
- Bonds to all metal surfaces and dries to form a high-purity, high metal content barrier that withstands extreme weather and temperatures
Weicon Zinc Spray is a very high quality form of cold galvanising spray used to permanently protect exposed metal. Once applied, Zinc Spray will form a fast-drying and extremely long lasting protective layer. This layer will protect the coated surface from moisture and prevent rust or cathodic corrosion.
Unlike many other types of Zinc Sprays and Cold-Gal sprays, Weicon Zinc Spray is manufactured using very high purity zinc flakes, rather than zinc pellets. The flakes naturally settle to form a more robust, harder to penetrate protective layer which allows our Zinc Spray to provide extremely good, long-term performance.
This performance has been tested in the DIN 53167 and DIN 50021 Salt Spray Test wherein a surface coated with Zinc Spray is bombarded with concentrated salt. In these conditions, Weicon Zinc Spray lasted over 550 hours. That may not sound like long but it is roughly equal to 7-8 years of natural weathering in Australian conditions.
Weicon Zinc Spray is manufactured from a combination of high purity (99.9% pure) Zinc and Aluminium Pigments combined with a styrenated alkyd resin binding agent. It will stick to all metal surfaces and does not need a primer to be applied beforehand. Once it’s dried, the percentage of metal in the dry film is a (very high) 70%.
Zinc Spray will be dust dry around 15 minutes after application and hardened after about 12 hours. It can be painted over, but should be left for 24 hours before you do so. Fully hardened Zinc Spray will withstand temperatures between -50°C and +500°C.
Coatings created with this Zinc Spray will be abrasion resistant and very long lasting. It has also been subjected to the DIN EN ISO 1519 mandrel bend test where it exhibited no hair cracking (important if you are applying it to parts that may more and shift like gate fixtures).
Zinc Spray has a colour that matches that of slightly weathered Zinc (RAL 9006) and is approved by the German-TUV (German technical inspection association). Zinc Spray also fulfils higher requirements than those required by the demanding, DIN EN ISO 1461 standard.
Applications for Zinc Spray - Cold Galvanising Corrosion Protection
- As an anti-rust primer for metal that will be painted or coated.
- For coating and protecting welded joints
- Protecting exposed metal edges on galvanised parts and fixtures
- For protecting and coating drilled holes
- As a conductive intermediate layer for spot welding
- In many, many other applications where metal parts need to be protected from corrosion.
What should I do to prepare the surface before I use Zinc Spray?
Zinc Spray does not require a primer but surfaces should first be cleaned, degreased and dried. Weicon Cleaner S is ideal for this task.
Can I use Zinc Spray on galvanised metal?
Yes. Zinc Spray has been colour coded to match the appearance of slightly-weathered zinc and will match in well with many galvanised parts. If you need something to match brand new, hot-dip galvanised metal we suggest our Zinc Spray – Bright Grade.
How long does it take to dry?
Zinc Spray will be dust dry after about 15 minutes and hardened after 12 hours. Please note these are approximates only as temperature and humidity can have an effect on the exact cure times. If you’re planning to paint over it, we suggest leaving it for at least 24 hours first.
