Use Instructions:

• Mix thoroughly with a drill-mounted mixer or paint shaker. Hand stirring is not enough.

• Duratec Surface Primer is designed to be applied when the ambient temperature and part temperature are both above 60°F.

• Catalyze with 1.75-2.25% MEKP Catalyst. Norox 925 works well. Mix well.

• Surface Primer can be applied by roller, brush or by spray. Spray with an HVLP gun, or with a gelcoat application system. Seek a fine spray, and use the lowest pressure that allows an even spray fan. (approximately 40 psi). A 2.0 mm tip is recommended.

• Apply at least 10 mils for even and complete cure. . Recoat before the Primer has set up and lost its tack. If the Primer cures completely wait at least eight hours, sand, and recoat.

• Additional solvent is not needed for most spray guns. If solvent is required, do not add Acetone or Styrene.

• Duratec Thinner is the best choice. Methyl Ethyl Ketone Solvent will work for most users. High quality urethane reducers are good choices. Lacquer Thinners are not recommended.

• Sand when the primer has cured. Start with the finest paper that will remove the surface profile. If sprayed well, 220 or 320 grit paper is a good starting point.

• Wait at least eight hours from the start of sanding before polishing or topcoating.

• Aqua Buff 1000 and 2000 are good choices for compounding and polishing Surface Primer.

• Duratec Pot Life Extender will extend the pot life by 2-3 times, and does not extend the cure time (spray only).
