ROOM TEMPERATURE CURED POLYURETHANE CAST ELASTOMER SYSTEMS

 

Specifications

 

 

DESCRIPTION:

 

Ezecast elastomers are two component, room temperature cured, solvent free reactive polyurethane systems. This material sets to give a highly elastic, non cracking, non-shrinking mass which can be used very effectively to protect a wide range of substrates used in conditions requiring high abrasion resistance and high impact resistance. Ezecast 113 and 213 form a putty whereas Ezecast 114 and 214 form a pourable / brushable mixture which is ideal for repairing damaged rubber components as well as protecting metal equipment from abrasion, impact and corrosion. Ezecast elastomers have excellent resistance to water, oil and grease coupled with excellent weather resistance. They can also be used for electrical insulation applications.

 

 

USES:

     

  • Repair of rubber belts, rollers, moulds and parts.

  • Repair of rubber lined equipment, vibratory feeder bowls, and de-burring equipment.

  • Lining of hoppers and chutes.

  • Protection of slurry pumps.

  • Protection of pump impellers, scrubbers and cyclones against abrasion.

  • Protection of pneumatic conveying pipes.

  • Impact resistant linings.

  • Insulation of bus-bars and cables.

 

APPLICATION:

 

The surface should be clean, dry and free from oil, grease and dirt particles.

 

PRIMING

 
Metal Surface: Metal surfaces should be shot blasted or mechanically cleaned to remove all traces of rust. Apply a thin layer of Ezecast 116 by brush on the clean metal surface. Allow it to dry for 10 minutes and then apply the Ezecast putty or liquid.

Rubber Surface: Brush on a thin layer of Ezecast 116 on the clean rubber surface and allow it to dry for 10 minutes and then apply the Ezecast putty or liquid.

 

APPLICATION PROCEDURE

 

Putty: Mix thoroughly Ezecast 113 and Ezecast 213 in the specified ratio and allow it to thicken for about 15 minutes. When the mixture is of the desired viscosity, apply the mixture (upto 5mm per coat) over the surface by means of a scraper blade. Ensure that no air bubbles are trapped in the material. Apply additional coats if required keeping a gap of 1.5 - 2 hours between coats. In case more than 3 hours elapse between application of two coats, apply a layer of Ezecast 116 to increase the inter-coat adhesion. Allow the coating to cure for 7 days at room temperature or 12 hours at 100 C.

Liquid: Mix thoroughly Ezecast 114 and Ezecast 214 in the specified ratio and immediately pour or spread over the primed surface to the required depth (max 5mm at a time).The rest of the procedure is same as that used for putty.

STORAGE AND PRECAUTIONS:

 

Ezecast components should be stored in a cool and dry area. They can be stored for 6 months in their original, unopened containers. Material from tin cans should be completely used up immediately after opening the can. Metal drums should be re-closed immediately after use. Ezecast may cause irritation to eyes, skin and mucous membrane, and is harmful if swallowed. While handling, all contact with eyes, skin and clothes should be avoided. Equipment used for application of Ezecast should be cleaned with xylene or toluene or MEK.

 


All Ezecast formulations are subject to strict quality control, innovations and improvements. The above information is given on the basis of our best knowledge and information and is for your guidance only. Specifications, however, are subject to change and no guarantee is given or implied.
