KP-2CF is a hi-solids, catalyzed, Chromate free epoxy primer. KP-2CF primer may be applied to bare steel, aluminum, fiberglass, magnesium and galvanized surfaces. Its tenacious adhesion, hi-build, and excellent durability, water and corrosion resistance makes it a logical choice for the basis of a long lasting paint job.
KP-2CF Epoxy Primer is the first step to a great long lasting custom finish.
Read "TECH PREP" thoroughly before you begin painting. Prepare vehicle using normal methods for acrylic lacquer or urethane. Surface to be primed should be free of wax, grease, rust, etc. Clean with KC-10.
Do not apply KP-2CF over old paint or uncatalyzed primers. KP-2CF may be applied over OEM factory primers, but for maximum adhesion and corrosion protection it is best to apply KP-2CF directly to the substrate. KO-SEAL II may be applied over properly prepared previously painted surfaces. See KO-SEAL II Tech Sheet for application information.
KP-2CF Epoxy Primer is a two part system. Aggressively mix KP-2CF Part A Base and KP-2CF Part B activator thoroughly before mixing the two parts together. KP-2CF Base is a yellow color and KP-2CF Activator is a blue color. Mix (by volume) 1 part KP-2CF Base (yellow) to 1 part KP2-CF Activator (blue). Up to 10 RU House of Kolor urethane reducer may be added for better sprayability and flow out. A 10 reduction will give approximately 1 mil dry film thickness per coat.
Stir mixed components well to ensure a thorough cure, use a paint shaker for best results. No incubation time is needed. Pot life is 3 hours at 70° F. Shop conditions can vary pot life.
Strain mixed primer into gun. Apply 2-3 wet coats with 50 pattern overlap. Apply 2 extra coats over body work. With a production gun use approximately 50 psi at the gun with a HVLP 10 psi at the air cap. Allow flash time between coats.
KP-2CF FLASH TEST- Allow Primer to dry dull before next coat is applied. Usually 10-15 minutes. Allow to dry a minimum of 6 hours at 70° F to dry or wet sand. Then apply KO-SEAL II and finish coats. See appropriate Tech Sheet for products used.
NOTE: IF MORE THAN 3 COATS ARE APPLIED, INCREASE DRY TIME TO AVOID SHRINKING.
NOTE: KP-2CF PREVENTS BLEED THROUGH OF STAINS IF MILLAGE IS 2 MILS OR ABOVE.
APPROXIMATE BUILD IS 1 MIL PER COAT WITH 10 REDUCTION.
FOR ADHESION COATS OVER BARE SUBSTRATES AND FOR FAST FILLING OF TOUCH-UPS IN REPAIR AREAS:
Apply 1 medium wet coat, let dry 1 hour and apply KO-SEAL II and finish coats.
Can be painted over in 1 hour without sanding using 1 medium wet coat.
IF NOT TOP COATED IN 24 HOURS, SAND PRIMER BEFORE APPLYING TOPCOATS.
Apply one medium wet coat of KP-2CF Epoxy Primer to bare metal substrate. Wait one hour and then apply 2-3 coats of KO-SEAL II. Allow to dry 2 hours before sanding then apply finish coats. See KO-SEAL II Tech Sheet for application of KO-SEAL II.
Prior to sanding, apply 827 Tempo Guide Coat. During the sanding process, the contrasting color of the guide coat will remain in pits and scratches and become a guide telling you how much sanding is required to smooth the KP-2CF. Remove the guide coat and a few more sanding strokes and move on. Be careful so you don't expose any body filler. If the primer is less than 2 mils, bleed through of filler is possible.
Block sand wet or dry. IF BODY FILLER IS EXPOSED, RE-PRIME WITH KP-2CF TO PREVENT STAINING.
Many dry sand KP-2CF with 100 or 150 grit, then re-prime with 2 or 3 more coats of KP-2CF. KP-2CF may also be wet sanded. Then simply seal coat with our KO-SEAL II and apply topcoats. FINAL WET SANDPAPER RECOMMENDED IS 320-400 GRIT.
NOTE: Do not use alkyd or synthetic sealers or primers with House of Kolor products as lifting may occur.
NOTE: To prevent bleeding or discoloration of base coats caused by body fillers, at least 2 mils of primer must remain after sanding. (1 coat equals approximately 1 mil when sprayed with production equipment using 10 reduction).
Allow dry time. We recommend 6 hours before sanding and finishing when 3 coats of KP-2CF is used at 70° F. Longer dry times are needed if more than 3 coats are applied. KP-2CF may also be force dried at 130° F for 45 minutes for faster sanding. The vehicle is now ready for KO-SEAL II, base coats and topcoats.
