BX520HT Clear Nano-Ceramic Primer is a High-Performance, High-Temperature Adhesion Promoting Primer, compatible with all nano ceramic coatings and a wide variety of substrates, and allows other Top Coats to be applied successfully.               DOWNLOAD DOCUMENTATION

For use on all surfaces, designed to create intrinsic bonding to the most “difficult of surfaces & products,” can even create a bond to silicon surfaces, polyethylene (PEG) sheeting, and the like.

Can maintain adhesion at deep cryogenic temperatures to extreme heat and/or direct flame environments. A high temperature, single component, ambient curable, semi-clear product. Thermal Stability (cured) <982.2°C / 1,800°F.

BX520HT can add adhesion to questionable surfaces when applying high-temperature coatings or other materials. Ideal for use on buildings, commercial and extreme use surfaces on vehicle & aircraft surfaces, such as glass, plastics, silicones, acrylics, polyethylene (PEG) sheeting, and the like, metals, polished metal alloys, painted, powder coated, or Gel-coated®.

How high is “High Temperature”? as high as “high-performance exhaust temperatures” if needed.

It is recoatable and may be applied as often as desired between nano ceramic coatings without sanding or abrading the previous coat. Ideal for concrete and graffiti when you are unsure of the previous surface. For use on a wide variety of coatings to create better intra-coat adhesion.

The BX520HT was chemically designed to create a covalent bond to substrate materials and allow for simple application methods, is applied as a thin film coating resulting in high-performance properties. Even so, surface cleanliness is still of the utmost importance.              DOWNLOAD DOCUMENTATION

Ensure the surface is prepared, clean, dry, and free from oils and other containments.

On metal & alloy component surfaces, if it is possible to do so, it is always preferred to have a light-blasted profile on the surface to aid in the coating’s physical bond.

  • The BX520HT covalently bonds well to all metal types, aluminum, titanium, stainless, metal oxides, most plastics, etc.
  • If it is possible to do so on composite substrate surfaces, it is also preferred to have a very light abraded profile on the surface to aid in the coatings’ physical bond.
  • A simple spray or dip application is acceptable when applied to cloth or woven goods, just enough to wet the surface to be bonded to.

Slightly mix or shake the BX520HT primer contents before applying; shaking by hand is acceptable.

  • If spraying by HVLP with a fine mist compatible with all – Nano-Ceramic Coatings, a fine spray tip (0.8) or similar is best. Apply at 2 to 3 microns maximum dry film thickness.

Top coat within 10 minutes of application – sooner is better. Immediate or wet-on-wet is ok; best is to wait 20 seconds; if using a powder coat, wait 30-45 seconds till you have dry to the touch – this should allow the top coat material to bond well.

  • If the primer dries longer than 10-minutes before top coating, re-apply the BX520HT as above, allowing the surface of the BX520HT to re-open-up again, thus allowing the top coat material to bond well.

The BX520HT primer may be applied directly to substrate surfaces where there are concerns of proper adhesion due to potential contamination from silicones, hard anodizing processes, etc.

The BX520HT primer is designed for use on a wide variety of substrates and tightly bonded cured coatings to achieve good intra-coat adhesion, where coating due to damage or similar is involved.

As with any new material, always test application and finished properties on a low-value test article or panel before working on valuable surfaces.
