Steel-It Epoxy Precoat 2 Gallon Kit 4210G
STEEL-IT 4210G is a two-component epoxy precoat in a 2 gallon kit with 316L stainless leafing pigment for metal and fab work. Parts A and B mix into a base coat that builds adhesion and corrosion resistance under STEEL-IT 4907 epoxy topcoat.
- Protects steel and aluminum as the first coat of the published STEEL-IT 4210/4907 epoxy system.
- Pairs with STEEL-IT 4907 epoxy topcoat for chemical and abrasion service for plant equipment.
- Coverage is approximately 215 sq ft per gallon at 3 mils DFT on smooth metal.

Key Features
- STEEL-IT 4210G is the 2 gallon kit of two-component epoxy precoat with 316L stainless leafing pigment.
- Parts A and B mix 1 to 1 by volume, then rest through a 45-minute induction before placement.
- One precoat at approximately 3 mils DFT is the standard first coat under STEEL-IT 4907 topcoat.
- The cured precoat builds adhesion and corrosion resistance for steel and aluminum equipment.
- Coverage is approximately 215 sq ft per gallon at 3 mils DFT assuming 20 percent overspray loss.
- STEEL-IT 4907 epoxy topcoat over 4210 completes the published epoxy system film stack.

Frequently Asked Questions
What jobs is STEEL-IT 4210G made for?
STEEL-IT 4210G is the epoxy precoat kit for steel and aluminum that needs a stainless-pigmented base coat before STEEL-IT 4907 topcoat. It is the first half of the published 4210/4907 epoxy system on plant and fab equipment.
What mix ratio and induction does the 4210 kit need?
Mix Parts A and B 1 to 1 by volume, then allow a 45-minute induction before placement. The application guide lists a 6 to 8 hour pot life after mix. Power agitation of each component before mix is required; hand stirring is not enough.
What film build does the epoxy system call for with STEEL-IT 4210G?
The guide typically calls for one coat of 4210 precoat at approximately 3 mils DFT, then one coat of 4907 topcoat at approximately 3 mils DFT. Approximately 6 mils wet film of 4210 targets approximately 3 mils DFT.
What temperature window applies when placing STEEL-IT 4210G?
Apply when ambient and substrate temperatures are 50 F to 100 F (10 C to 38 C), relative humidity is under 85 percent, and the substrate stays at least 5 F above dew point. Dry to touch is approximately 2 hours; recoat window to topcoat is 12 to 24 hours. If not topcoated within 24 hours, light scuff-sanding with approximately 200 grit is required.
Which other STEEL-IT packs sit with this epoxy precoat?
The live sister precoat kit is STEEL-IT 4210Q (2 quart). The matching topcoat is STEEL-IT 4907G (2 gallon) or 4907Q (2 quart). 4907 is a different product from 4210 and is not a size swap of this page.
What coverage does the guide list for 4210?
Practical coverage is approximately 215 sq ft per gallon at 3 mils DFT assuming 20 percent overspray loss. Tack-free to handle is approximately 12 hours. Full system service timing follows the 4907 topcoat schedule after the topcoat is placed.
