1. What is TopShield?

TopShield is a high performance ceramic-PTFE coating specifically designed to fully address the highest demands of the Mil&LE segment. Co-developed with the major European firearm producers, the innovative TopShield formula is now available for everyone who wants to protect and customise their weapon or accessory.

 

2. Ceramic? Why?

Ceramic, if present in significant quantities, allows to get an extremely hard and scratch-resistant coating layer and improves the resistance to chemical elements.

 

3. What is the ceramic content in TopShield?

The Military&LE segment requires a 10% ceramic content (at least). Of course we cannot declare the exact percentage of ceramic, but we can assure you that it is abundantly over 10% unlike traditional “ceramic” coatings that contain only 1% o 2%.

 

4. What will I find in the package?

 

In the package you will find: chosen coating (part A - TopShield 2K/TopShield 2K LT), activator (part B - TopShield 2K) or hardner (part B - TopShield 2K LT), thinner (part C) in the correct quantities. Use a precise weight scale to combine the correct quantities as disclaimed in the technical data sheet.

 

5. How should I prepare the product?

 

To prepare the product you have to: 1) blend the chosen coating (part A), 2) add the activator (part B – TopShield 2K) or hardner (part B – TopShield 2K LT) in the correct quantity as disclaimed in the technical data sheet, 3) add the thinner (part C) in the percentage of 15-30%.

 

6. If I exceed in the activator/hardner quantities, what should I do?

 

In this case, it is possible to readjust the quantity of the part A in order to get again to a correct activation/catalysis ratio.

 

7. After the activation of the product, how long can I use it?

 

TopShield 2K and TopShield 2K Titanium lines, where it is used the activator, can be used up to 30 days after the activation. TopShield 2K LT line has a shorter pot-life and you must use it by 4 hours from mixing part A and B.

 

8. As the product is prepared, should I filter it?

 

Yes, it is always recommended to filter the product by using the reusable filters (you can find them here).

 

9. How much coating should I use for…?

 

Usually, you will use the following quantities of coating (part A) for:

  • Gun barrel: 25 g

  • Gun slide: 15 g

  • Upper receiver: 25 g

  • Lower receiver: 25 g

  • Handguard: 20-40 g depending on width and complexity

  • Magazine: 5-10 g

  • Optic: 15-25 g

 

9. I have a gun slight with old coating applied, should I remove it?

 

Yes, all previous treatments have to be removed because we cannot guarantee the adhesion of TopShield on them since thay have different chemical characteristics.

 

 

10. Where can TopShield be applied?

 

TopShield can be directly applied on metallic surfaces which have been previously sandblasted. If it is not possible, you can treat aluminium surfaces with our specific product (TopCleaner EP).

 

11. Should I wash the parts before sandblasting/coating them?

 

Yes, all parts have to be perfectly cleared before sandblasting/coating. They can be degreased with our specific remover, TopCleaner, and the aluminium parts can be treated with our etching solution, TopCleaner EP, to upgrade the final performances.

 

12. If I don’t perfectly sandblast the parts, will TopShield tear away as the other “ceramic” coatings?

 

Absolutely NO! TopShield guarantees optimal resistance even on smooth (degreased) surfaces, even if it is reccomended to sandblast every part to upgrade the final performances.

 

13. Which tool should I use to spray the coating solution?

 

Application is super easy with a simple spray gun with a needle of 0.8-1.2 mm. You can find the perfect spray gun with the correct dressing here.

 

14. How should I hang the to-be-coated parts?

 

We recommend to tie the to-be-coated parts with metallic wire or use metallic supports that resist to oven cure. If you use the TopShield LT line, you do not mind the support because the part will be air cured.

 

15. How should I treat, for example, the slides?

 

A video on how to use the product will be soon available, but in the meanwhile we recommend to:

  • Adjust the settings of the spray gun and spray on a cardboard in order to evaluate the quantity of coating, the jet radius and air compression;

  • Reduce as much as possible the quantity of the sprayed coating;

  • At the beginning, cover the zones difficult to reach, the blind points, the muzzle and the sliding guides, trying to apply the minimum thickness;

  • After that, cover the external part as the part results wet at sight;

  • Let to dry at rokom temperature for 15 minutes;

  • Put in the oven and cure it at 180°C for 30 minutes (or at 160°C for 60 minutes).

 

16. So can I treat even the most critical zones, like the sliding/stem guides?

 

Absolutely yes! The presence of dried lubricants guarantees a long lasting self-lubrication as well as a durable protection from corrosion and chemicals aggression. You just need to apply the minimum thickness possible.

 

17. How long should the part stay in the oven?

 

If treated with TopShield 2K or Topshield 2K Titanium lines, the coated part has to be oven cured at 180°C for 30 minutes, regardless of the time required to reach that temperature.

 

18. Once cured, may I assemble the part immediately after?

 

Yes, you just have to wait for complete cooling down.

 

19. If I applied the product wrong or dots showed up, what should I do?

 

Usually it is enough to sand lightly and retouch the zone, oven curing the part again. It is necessary to verify every time the adhesion and the aesthetic quality.

 

20. Can I do camouflage works with TopShield?

 

We do not recommend to use the HT lines (TopShield 2K Standard and Titanium Series) because the high content of dried lubricants compromises the adhesion of the following layer. TopShield 2K LT line, on the other hand, is perfect for this type of solution.
