Prepbond

MC-Prepbond 100 is Wasser’s universal, low VOC, moisture-cure urethane primer for ferrous and non-ferrous metal substrates. The design benefit of the penetrating nature of this primer/sealer allows for superior adhesion to marginally prepared surfaces when compared with most industrial coatings. It is ideal for use as a tie coat over most existing coatings and can be used in red lead encapsulation systems.

Surface Preparation Application Information

MC-Prepbond 100 can be applied by brush, roll, airless spray and conventional spray application. Follow proper ixing instructions before applying. m

Mixing:

Material temperature must be 5° F above the dew point before opening and agitating.

Power mix thoroughly prior to application.

Do not keep under constant agitation.

Apply a 3-6 oz solvent float over material to prevent ntrusion and cover pail. moisture i

Brush/Roller:

Brush: Natural Fiber

Roller: Natural or synthetic fiber cover Nap: ¼” to ⅜” Core: Phenolic Reduction: Typically not required. If necessary, reduce with MC-Thinner 100.

Airless Spray:

Pump Ratio: 28-40:1 Pressure: 1800-2000 psi

Hose: ¼” to ⅜” Tip Size: .011-.015

Filter Size: 60 mesh (250 μm) reduce with MC-Thinner or MC-Thinner 100.

Atomizing Air: 45-75 lbs.

Fluid Pressure: 15-20 lbs.

Hose: ½” ID; 50’ Max reduce with MC-Thinner or MC-Thinner 100.

Reducer: MC-Thinner, MC-Thinner 100, (if VOC regulations restrict thinning, use MC-Thinner XMT). Reduction is typically not required. If necessary, thin up to 10% with recommended thinner. Thin in accordance with local and ederal regulatory standards. f Clean up: MC-Thinner, MC-Thinner 100. If Wasser thinners are not available, use MEK, MIBK, Xylene, a 50:50 blend of Xylene and MEK or MIBK, or acetone for clean up nly. Do not add unauthorized solvents to a Wasser coating. o

Application Conditions:

Temperature: 20°-100° F (-8°-38° C) This temperature range should be achieved for ambient, surface and material temperature. Substrate must be visibly dry. On applications below 33° F, Steel temperatures should be 5°F above the dew point temperature. MC-Thinner 100 is recommended for spray application in temperatures above 0°F. 9

R elative Humidity: 6%-99% Coating Accelerator: PURQuik® Accelerator. See asser’s PURQuik® Accelerator Product Data for information. W

Storage: Store off the ground in a dry, protected area in temperature between 40-100°F (4-38° ). MCU containers must be kept sealed when not in use. Use a solvent float to reseal partial containers.

C

Ferrous Metal Use SSPC-SP1 solvent cleaning to remove oil and grease or other contaminants prior to employing surface reparation methods. p

Blast Clean surfaces for immersion or severe service rojects to SSPC-SP10/NACE No. 2 Near White Metal finish. p

Prepare surfaces for non-immersion or atmospheric service projects using SSPC-SP12/NACE No. 5 Low Pressure Water Cleaning methods to remove surface contamination.

Supplement SSPC-SP 12 LPWC with SSPC-SP2 and 3 Hand and Power Tool Cleaning or SSPC-SP6/NACE No. 3 Commercial Blast Clean methods where areas show excessive corrosion, or loose and failing paint (feather edges of sound, xisting paint back to a firm edge). e

Areas cleaned to bare metal should exhibit a surface profile that will support mechanical coating adhesion.

Aggressive surface profile may require additional coating pplication to ensure proper coverage. a

Corten Steel Prepare surfaces using SSPC-SP12/NACE No. 5 Low

Pressure Water Cleaning methods. Supplement SSPC-SP 12 LPWC with SSPC-SP2 and 3 Hand and Power Tool cleaning where areas show excessive corrosion. Use SSPC-SP1 solvent cleaning to remove oil and grease prior to surface preparation ethods. m Aluminum/Galvanized/Non-Ferrous Metals

Prepare surfaces using SSPC-SP1 Solvent Cleaning and SSPC-SP12/NACE No. 5 Low Pressure Water Cleaning methods to remove surface contamination. Supplement weathered galvanized surface preparation with SSPC-SP2 and 3 Hand and Power Tool cleaning to remove excessive corrosion and impart surface profile on bare metal. Supplement new galvanized surface cleaning with mechanical abrasion to impart urface profile and support mechanical adhesion. s

Good Practices MC-Prepbond 100 is designed for application to tightly adhering rust. Heavy pack rust must be removed.

The surface to be coated must be dry, clean, dull, and free from dirt, grease, oil, heavy rust, mill scale, salts or any other surface contaminants that interfere with adhesion.

Ensure welds, repair areas, joints, and surface defects exposed by surface preparation are properly cleaned and treated prior to coating application.

Areas of oxidation after surface preparation and prior to coating application, should be prepared to specified standard

Consult the referenced standards, SSPC-PA1 and your Wasser Representative for additional information or recommendations.
