Identification & Functionality
- Technologies
- Product Families
- Product Highlights
- The coating is a high solids system which can be applied to a dry film thickness of 6 to 20 mils (150 to 500 microns) and has no VOC (Volatile Organic Compound) content.
- XP61 can be formulated to address specific application needs such as corrosion and erosion resistance, slagging and fouling mitigation and specific thermal management requirements.
- XP61 bonds well to properly prepared carbon steel or stainless-steel substrates.
- Working properties of the coating exhibit an extended shelf of up to one year.
- Upon curing XP61 becomes a durable ceramic coating that will provide protection to boiler and furnace tubing and other steel substrates to 1,832°F and will withstand thermal cyclic conditions to 2,100°F
- XP61 may also be applied as a thermal spray sealer to prevent coating permeation in high temperature environments.

- Surface Preparation
Surfaces to be coated must be dry and free of all chlorides, weld splatter, oil, dirt, grease, liquor and all other contaminants. Round off all rough welds and sharp edges. Abrasive blast to achieve a NACE 1/ SSPC-SP5 (white blast) specification. Garnet or other hard sharp materials are recommended for abrasive blasting. A 3 mil (75um surface profile is recommended.
- Application Instructions
- Surface temperature must be a minimum of 5°F above the dew point. Do not apply to steel temperatures below 50°F
- Do not exceed dry film thickness recommendations.
- XP61 is normally sprayed but if applied by brush mechanically mix container every 5 minutes during application to assure proper particle suspension.
- Warning : Do not thin XP 61 with any thinner as poor film characteristics may occur.
- Application to hot surfaces (+200°F, 93°C) tends to promote dry spray and may cause blistering to occur. XP 61 normally dries by ambient air drying. If the temperature is below 70°F and the humidity is high slower drying will occur. Low temperature oven or heat drying may be used to accelerate the drying time. Do not exceed 200°F during accelerated drying.
- XP 61 should be applied in minimum of 3 (three) coats of 3 mils (75 microns) per coat. Each coat must completely dry to the touch before the second coat is applied. If heat cure is used to accelerate drying assure that the temperature does not exceed 200°F If thicker coating is required allow each coat to completely dry to the touch before subsequent coats are applied. Moderate heating can be applied between coats if required.
- Curing Requirements
After application allow the coating to air dry above 50°F for minimum 24 hours.
- Cure for 1 hour at 180°F to 200°F
- Cure for 1 hour at 300°F to 350°F
- Cure for 1 hour at 425°F to 460°F
- Equipment
Conventional or airless spray is recommended. Proper SSPC coating application procedures should be followed when applying XP61. Contact Fireside Coatings for proper surface preparation and application specifications.
- Mixing
Use mechanical agitation for initial mixing and during application. Mix materials until smooth and uniform in consistency. While spraying, adjust mixing speed to allow for material suspension without cavitations. It is recommended to screen the material before application.
