Epoxy Primer Resin

Frequently Bought With
In an epoxy primer, the resin component is responsible for providing adhesion to the surface and acting as a binder for other coating components. It also helps the primer to cure and form a protective layer. The resin creates a strong bond between the primer and the substrate, ensuring the primer stays firmly attached.
This NAPCO Epoxy Primer Resin is one component of our 2-part, spray-on Epoxy Primer system designed to be used on porcelain, cast iron, steel, or ceramic surfaces. Our low-build primer system is designed to hold tightly to the surface while retaining the flexibility that resists cracking. This fast-dry tub epoxy primer is applied in 3 - 4 light tack coats without the worry of unevenness or runs. It takes just 5 - 10 minutes to dry. It even covers up minor pits or imperfections.
**RESIN MUST BE MIXED 50/50 WITH EPOXY PRIMER CATALYST! ALLOW INDUCTION TIME OF AT LEAST 15 MINUTES AFTER MIXING**
Why Refinishers Love it:
- Primer system is fast drying
- Durable and flexible
- Original NAPCO formulation

What does the Epoxy Primer Resin do in the refinishing system?
The Epoxy Primer Resin provides the primary adhesion layer between the surface and the topcoat. It acts as a binder that helps the primer bond securely to porcelain, cast iron, steel, and ceramic surfaces while forming a durable base for refinishing.
How is the Epoxy Primer Resin used with the catalyst?
The resin must be mixed at a 50/50 ratio with NAPCO Epoxy Primer Catalyst. This combination activates the curing process and ensures proper adhesion, durability, and performance of the primer system.
Is induction time required after mixing the resin and catalyst?
Yes. After mixing the resin and catalyst, an induction time of at least 15 minutes is required. This allows the chemical reaction to begin before application, helping achieve optimal bonding and curing.
What surfaces can this epoxy primer be applied to?
This epoxy primer system is designed for use on porcelain, cast iron, steel, and ceramic surfaces. It is commonly used in tub, tile, and surround refinishing applications.
How is the Epoxy Primer Resin applied?
The primer is applied as a spray-on system in 3 light tack coats. Each coat dries quickly, typically within 5 to 10 minutes, allowing for smooth, even coverage without runs or uneven buildup.
Does this primer help with surface imperfections?
Yes. The Epoxy Primer Resin can help fill minor pits and imperfections caused by sanding or corrosion, creating a smoother surface for the topcoat and improving the final finish quality.
