ARCOR® 1321K
- Chemical Family
- Epoxy & Epoxy Derivatives
ARCOR® 1321K is a solvent-free bisphenol F coating specifically formulated for both immersion and non-immersion service, particularly in aggressive environments. This self-priming coating creates a robust and chemically resistant layer on ferrous and non-ferrous metals as well as concrete surfaces. With its low viscosity and excellent flexibility, ARCOR® 1321K is particularly well-suited for external applications subjected to aggressive exposures. It can be applied by hand or spray onto metals or concrete, and its long pot-life and overcoat window make it ideal for larger surface area applications using airless or plural component spray systems. The addition of Kevlar® enhances the coating's resistance to impact, abrasion, and flex while retaining its ability to be sprayed. Additionally, ARCOR® 1321K exhibits excellent UV stability, ensuring long-lasting performance in various environments. ARCOR Epoxy Technologies can tailor make or reformulate the product to suit customer needs. Please reach out if you need a custom formulated product!

- Mixing
Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade scraping sides and bottom of container or mixing board. Mix by Volume 2 parts Base to 1 part Activator. Or by weight 100 grams base to 36 grams activator. Mix thoroughly to produce an even colored and streak-free material.
- Clean Up
Clean tools immediately after use with M.E.K. or similar. Isopropyl Alcohol can be used in solvent restricted areas.

- Application
Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating. Trim or tape to <1" nap. Roller: good quality 3/8" nap. Plural Spray: 0.031-0.035 tip, 2,200-3,500 PSI, Heat to 130ºF Base, 100ºF Activator. 30 mesh screens. Heated hose @ 140ºF Airless Spray: 0.031-0.039 tip, 4,000-4,500 PSI(45:1). Add 6-oz/gal of MEK or Acetone.(Caution: Short Pot-Life) Conventional Spray: Not Recommended. All spray equipment should employ traps to prevent water and oil from contaminating coating and screens to prevent particulate contamination.

- Surface Preparation
Steel surfaces are to be abrasive blasted with chloride free abrasive. Exterior applications to SSPC SP-10 Near White metal finish. Immersion applications to SSPC SP-5 White metal 3 to 5 mil profile. Grind flat all burrs, weld seams, radius sharp edges. Fresh blasted ferrous surfaces to be should be coated immediately with ARCOR™ 1321K to prevent oxidation of surface. For very large areas ARCOR™ EE-80 can be used as a pre-prime to help hold the blast.
- Overcoat and Cure Time
By brush, roller or squeegee recoat while material is still soft, but tack-free, between 1-12 hours at 77ºF(25ºC). If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. By spray application a single coat to 20 milsis recommended. For multiple coats, recoat between 1-12 hours at 72ºF. Full cure before chemical immersion 72 hours at 72ºF. Add 12 hours additional cure time for each 10ºF below 72ºF. Subtract 12 hours of cure time for each 10ºF above 72ºF. Force Cure with heat for best performance for 4 hours at 150ºF(66ºC), 12 hours at 100ºF( 38ºC).
