Painting Preservation

Description

DEV PU PRIMER is a single component moisture cure polyurea primer, combining Zinc and Micaceous Iron Oxide (MIO) into our proprietary blend moisture cured resin. This primer is designed for outstanding protection of steel from corrosion in high humidity climates, service under immersion, splash zone and areas with permanent condensation. The properties of the resin, high quality zinc and lamellar MIO, makes DEV PU PRIMER the perfect primer that provides both barrier and galvanic protection simultaneously.

Storage

Store off the ground in a dry, protected area in temperature between 4 ºC to 30 °C (40 ºF to 86 °F). Containers must be kept sealed when not in use. Use a solvent float to reseal partial containers.

Clean up

PU-Thinner, PU-Thinner 25 and PU-Thinner 50. If PU- Coatings thinners are not available, use MEK, MIBK, Xylene, a 50:50 blend of Xylene and MEK or MIBK, or acetone for clean up only. Do not add unauthorized solvents to a coating of PU-Coatings.

Application

DEV PU PRIMER can be applied by brush, roll, airless spray and conventional spray methods (one grade only). Follow proper mixing instructions before applying.

  • Relative Humidity: 6% to 99%* PU-Quickcure is advised when relatives humidity’s are below 40%.
  • Temperature: -20 °C to 75 °C (-4 °F to 167 °F) This temperature range should be achieved for ambient, surface and material temperature. Substrate must be visibly dry.
  • Coating Accelerator: PU-Quickcure. See PU-Quickcure Product Data for information.

Mixing

Material temperature must be 5 °F (3 °C) 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 (9-18 cl) solvent float over material to prevent moisture intrusion and cover pail.

Surface preparation

For minimum surface preparation, use conscientious hand and power tool cleaning methods in accordance with ISO 8504-3 or SSPC-SP2 and 3 to remove corrosion and loose or failing paint to ISO 8501-1 St2 or SSPC-SP2 and 3 (visual standard SSPC vis 3). Feather-edges of sound, existing paint back to a firm edge.

Description

Dev Pu Coat is a single component moisture curing intermediate coating, containing MIO and it is also a (non-UV) topcoat for new construction and maintenance projects.

Dev Pu Coat has proven outstanding barrier performance when used for immersion, splash zone or atmospheric exposure service. Dev Pu Coat is available in a light colour to facilitate interior tank inspection. Dev Pu Coat is also a primer for non-ferro.

It is ideal for use as a tie coat over most existing coatings and can be used in red lead encapsulation systems. Dev Pu Coat is also a standard primer for concrete.

Applications

Dev Pu Coat can be applied by brush, roll, airless spray and conventional spray methods (one grade only). Follow proper mixing instructions before applying.
