Application

|
Application Instructions
|
|
Spray application for best results using conventional, airless, HVLP or cup gun. The air source must be dry. The compressed air source should be
outfitted with air dryers as needed to supply moisture-free air. Use pressure feed equipment such as high volume, low pressure equipment or
conventional equipment. Airless: Use reversible carbide tip with orifice size of 0.021-0.027 inches. If applying with roller, use short nap, such as 1/
4” (0.244mm). After thoroughly mixing EP-PRIME 2000, strain with a standard paint strainer and pour into the spray equipment. Apply a first pass
of five to six mils (125-150 microns) WFT and allow sufficient time for solvent to flash off. At 72°F (22.2°C), 30-40 minutes is sufficient. Apply a second
pass of five to six mils (125-150 microns) WFT for a total DFT of eight to ten mils (200-250 microns). Apply additional mils without incurring runs
or sags if the finished product requires thicker coverage per manufacturer’ s instructions. Whenever possible, apply second coat in a cross-coat
method. CLIMATE - Use EP-PRIME 2000 only if substrate temperature and ambient air temperature is above 40°F(4.4°C). No coating should be
permitted when substrate is wet from rain or dew, when surfaces are less than 5°F(3°C) above the dew point and holding or when relative humidity
is greater than 85%. Moisture will inhibit the catalyst reaction and EP-PRIME 2000 will not cure or perform properly.
|
|
|
Surface Preparation
|
|
Bonding strength depends on proper preparation of the surface to be protected for long-term performance of the product. The substrate should be free
of oil, grease and salt/chloride contamination. Specifications call for a white metal (NACE 1, SSPC SP5, Swedish Standards SA-3) cleanliness with
a 2.5 mil (62.5 microns) anchor profile. Surface preparation should be no less than a near white ( NACE 2, SSPC-SP10, Swedish SA 2 1/2) finish.
Cleanliness is the most important step to produce a surface that will perform and last. Call E Paint Company for surface preparation recommendations
of materials such as aluminum, plastic and/or fiberglass.

Mixing
|
|
EP-PRIME 2000 contains a high loading of ceramic particles which must be placed into full suspension with the epoxy resin prior to application. EP-PRIME
2000 is packaged in two cans, Part A Base Component (resin and ceramics) and Part B Converter Component (curing agent). Shake Part
A Base Component with a Cyclone air-powered shaker or mix Part A Base Component with a paddle mixer until all ceramic particles are suspended
in the resin. Time required to place ceramics into suspension varies according to temperature and length of material storage time. At 72°F (22.2°C),
generally a four to six minute shake will place ceramic particles into suspension. Regardless of time needed, shake all ceramic material into
suspension prior to proceeding. Failure to properly mix will keep EP-PRIME 2000 from performing or curing properly. Check the can to assure all
solids are in suspension prior to proceeding to the mixing step. Combine Part A Base Component and Part B Converter Component and stir until both
parts are thoroughly mixed. Shaking can cause excessive heat build up thus causing curing problems. Stirring time is temperature dependent, but
it should only take three to four minutes to thoroughly mix the components. No induction time is needed before application.

Pot Life / Shelf Life
|
|
Pot life of EP-PRIME 2000 at 72°F (22.2°C) is 1 hour. Colder temperatures will increase the pot life and warmer temperatures will decrease the pot
life. Keep cans out of direct sunlight to prevent heat buildup. EP-PRIME 2000 has an indefinite shelf life. Preferred storage/usage is a dry enclosed
area under 85°F (29°C), used within 2 years. However, if stored more than two years above 85°F (29°C), call E Paint Company Technical Support
prior to use.

|
|
Thinning
|
|
Adjust viscosity with small amounts of Methyl Ethyl Ketone (MEK) or Acetone. Use caution when adjusting the viscosity as a little thinner goes a
long way. Only a small portion of the total solution is epoxy resin and the resin is the only ingredient that can be thinned. Thinning dilutes the high solids
of the EP-PRIME 2000, creates excessive overspray and can cause color changes in bright colors.

|
|
Holiday Detection / Repairs
|
|
EP-PRIME 2000 is classified as a thin-film coating and should be tested for defects and holidays using a 67 1/2 volt, wet sponge spark detector set
at 80,000 ohms resistance, such as a Tinker and Rasor model M-1. REPAIRS If application of the coating is less than seventy-two (72) hours old
and has not been exposed to contamination, repair by wiping with MEK or Acetone and then re-apply EP-PRIME 2000. If contaminated or more than
72 hours old, first sand with appropriate grit sandpaper, then repeat repair process.
|
|
|
Cure Times
|
|
A two-pass film of 8-10 mils DFT (200-250 microns) air dries to a touch-dry finish within 4 hours at 72 o F (22.2 o C) and dries to a 70% cure in 17 hours.
Cure times lengthen at lower temperatures and shorten at higher temperatures. Coating should be fully cured before placing into service.
|
|
|
Cleaning
|
|
Purge and clean spray equipment within 30 minutes of the final spray. Flush equipment with MEK or Acetone until solvent sprays clear. Disassemble
and clean equipment to manufacturer’ s recommendations. Material left in spray equipment will solidify and damage equipment. Use precautionary
measures applicable to any catalyzed material.
