Two component solvent free epoxy primer
Vetoprime EP391 is a two-component solvent-free epoxy. It is a specialty industrial primer for the Vetorep and Vetotop product range. It is applied to prepared concrete and cementitious substrates to seal the substrate and enhance bonding with topcoats. The product can be used as a stand-alone product in internal applications as a seal coat to harden cementitious surfaces and prevent dusting.
Vetoprime EP391 is designed to be the ideal primer for damp concrete.
Pack Size: Vetoprime EP391 is supplied in a 4 Liters kit.
Stated consumption data are for general guidance. Actual consumption depends on the nature of the substrate, method of application, and wastage.
The original Vetoprime EP391 sealed container has a shelf life of 12 months, provided to store clear ground in a dry, shaded place below 35ºC.
Priming of joint edges to receive urethane, epoxy, and polyurea-based sealants.
Priming of concrete slabs and walls to receive solvent-free epoxy, urethane, MMA, polyurea, hybrid coatings, screeds, and self smoothening toppings.
Priming of concrete substrates to receive epoxy and urethane-based repair mortars.
Priming of cementitious screeds to receive epoxy, urethane, and resinous toppings.
Mix Vetoprime EP391 as supplied. Add the entire content of the hardener container to the base container and mix thoroughly for about 2 minutes. Once mixed, apply the Vetoprime EP391 immediately in a thin continuous film using stiff brushes or rollers. Avoid over-application and puddles.
Allow Vetoprime EP391 to become tack-free before applying epoxy coating (unless otherwise specified) but well within the open time specified for the given temperature.
The hotter the substrate, the more quickly the primer will become dry.
Clean all tools and equipment immediately after use with Vetonit Solvent XX400.
It is essential to apply Vetoprime EP391 to a sound and clean surface to achieve maximum bond strength between the substrate and the coating/repair products.
Concrete substrates should be at least 28 days old, and the relative humidity of the concrete is 75% or below. Remove laitance deposits on new concrete by light grit blasting, mechanical scrabbling, or grinding.
Where heavy contamination by oil and grease occurs or existing coatings present, it is essential to remove all contaminations.
At temperatures below 20ºC, the cure rate will be slower. Conversely, at temperatures above 20ºC, the cure rate will be faster.
Some people are sensitive to epoxy resins, so gloves and a barrier cream shall be used when handling these products. If contact with the resin occurs, it must be removed before it hardens, with a resin removing cream follow by washing with soap and water. Do not use solvent.
During use, avoid inhalation of solvent and contact with skin and eyes. Wear suitable protective clothing, gloves, eye protection, and respiratory protective equipment. In case of contact with the eye, rinse immediately with plenty of clean water, and seek medical advice. If swallowed, seek medical attention immediately – do not induce vomiting.
Vetoprime EP391 is non-flammable.
