AT 1620 - ALPHATEK NON-STICK
AT 1620 is a FDA compliant base coat sealer for porous metal cooking surfaces (e.g. grills, wire screens, etc.). AT 1620 is generally used as a primer / sealer. Apply AT 1660 to create a non-stick surface. AT 1620 is easily applied and cures under ambient conditions. It has excellent adhesion and provides long-term performance. AT 1620 is inert (benign) material when cured. Cured coating is free from any harmful fumes.
Proudly manufactured in the USA.
- High performance primer/sealer for cooking surfaces.
- FDA compliant for food contact.
- Excellent adhesion. Creates a covalent bond to the substrate and helps fill-in micro pores and seal corners.
- Inert (benign) material when cured. Cured coating is free from any harmful fumes.
- Applies thin (5 – 15 micron dry film thickness).
- Ambient cure.
- Easy to apply. Curable by ambient air (accelerated oven curing possible).
- RoHS and REACH compliant.

Dry to Touch Time (@ 77°F / 25°C) *Exposing to a warmer air flow (not exceeding 110°F) will decrease drying time. |
15 – 25 minutes (average) |
| Ambient Cure (Full Properties) | 5 days |
|
Cure Time (@350°F) *Coating must be dry to touch before subjecting to elevated temperatures. |
30 – 40 minutes |
Primary use is as a base coat sealer before the application of AT 1660 or AT 1661 – Non-Stick Coatings. Perfect for porous surfaces or welded joints that need to be filled or sealed before applying a non-stick topcoat.
- Wire screens
- Grilling surfaces
- Barbeque grills
