Features & Benefits
- Ready-to-Use Product Features
- Advantages
- It can be used as a primer for all Macrylex (MMA) based systems.
- Perdure UPr must be sued as a barrier primer applied in one or two coats as needed to achieve a pinhole-free finish when applying Macrylex over an existing epoxy basecoat.
- Excellent primer for a variety of surfaces.
- Barrier primer for applying Macrylex systems over epoxy.
- Superior wetting out properties over sound, rusty steel.
- Can be recoated in 1 to 2 hours and can be coated with most resinous coatings.
- Corrosion-resistant: Passes 12,000 hrs. in salt cabinet.
- Excellent high-temperature resistance.
Applications & Uses
- Markets
- Application Method
- Compatible Substrates & Surfaces
- Cure Method
- Special Conditions
- Do not apply over frost, wet/damp surfaces, or in very high humidity conditions.
- The clear formulation will yellow over time if used as a finish coat.
- Must be recoated within 24 hours.
- Seal partially used containers to prevent material from reacting with moisture in the air.
- Coverage
- Use on concrete or as a barrier coat (2 coats recommended): 250ft²/gal/coat
- Steel: 866ft² at 1 mil DFT
- Surface Preparation
Concrete:
- Shot blast or grind to a medium grit texture similar to 60 grit sandpaper or CSP-3.
- Steel: Sandblast to an SSPC SP6 “commercial” blast finish.
- When blasting is not appropriate, remove all loose rust and mill scale by power wire brushing or hand tool cleaning.
- A tightly adherent rusty surface is acceptable.
Galvanized Steel:
- New Brush blast per SSP - SP7.
- Old, weathered or rusty: Remove all oil, grease, dirt, and other foreign matter.
- The surface should be reasonably clean, dry, and free of contaminants.
- Remove all loose rust, etc., as outlined under steel.
- Previously Painted Surfaces: Remove all loose, peeling, or blistered paint and any other surface contaminants.
- Make sure the surface is sound and dry.
- Installation
- Mix Perdure UPr so that the aluminum pigment is thoroughly dispersed in the resin and uniform silver color is achieved.
- When using Perdure UPr over an extended period, stir occasionally to maintain uniform mixing of the material.
- It is applied with a 3/8” nap roller.
- Roller covers should have a phenolic core.
- Perdure UPr may be applied at temperatures between 25°F and 140°F.
- It cures to a tack-free in 1 - 2 hours and can be recoated in 2 to 24 hours at 75°F with 50% RH.
