Duromar HPL-2136 CNT High Performance Lining

DUROMAR HPL-2136 CNT is a 100% solids, carbon nanotube reinforced 2-part epoxy coating system. This abrasion resistant coating was engineered to enhance the structural integrity and reinforce badly damaged or corroded structures. This high flexural strength coating may be applied to concrete or steel up to 250 mils in a single coat to provide a continuous, high strength, erosion resistance reinforcement.

All Duromar products are formulated based on over 25 years of experience, laboratory tests, material data, field installations, and technical publications, which we believe to be, to the best of our knowledge, accurate and reliable. This information is intended to be used for guidance only. Because the only true reliable test is one that is in actual operation, Duromar will make available at no charge samples of materials for that testing purpose. Duromar, Inc. has no control over either the quality or condition of the substrate, or the many factors affecting the use and application of the product. Duromar, Inc. does, therefore, not accept any liability arising from loss, injury, or damage resulting from such use or the contents of this data sheet (unless there are written agreements stating otherwise). The data contained herein is liable to modification as a result of practical experience and continuous product development. This data sheet replaces and annuls all previous issues, and it is, therefore, the user’s responsibility to ensure that this sheet is current prior to using the product.

Force Curing
Force cures are recommended for severe service conditions as both physical and chemical properties are enhanced. Force curing should not start until material has firmly set. Contact DUROMAR for specific instructions.
Shelf Life This product has a minimum shelf life of one year when stored in a dry area at 50 to 100F in the original sealed container.
Handling and Safety
Warning! Eye and skin irritant. May cause dermatitis and sensitization.

Always read and understand the product MSDS.
Avoid contact with eyes, skin or clothing. Avoid breathing vapor, mist or spray. Use with good ventilation.

First Aid
In case of contact:

Eyes: Immediately flush with water for at least 15 minutes.

Skin: Immediately remove from skin with dry cloth followed by thorough washing with soap and water.

Inhalation: Remove to fresh air. If breathing is difficult, give oxygen.

Ingestion: Give large quantity of milk or water, induce vomiting. Contact a physician immediately.

Store all product in a clean, warm area where the temperature remains between 50 to100F (10 to 38C). Cold products are very viscous and will be difficult to mix and apply.

Products shipped during cold months can remain cold for many days even when stored as recommended. Paste or trowel applied products will remain cold longer than liquid or spray applied products. Heating of the individual components may be required to bring the products to the recommended temperatures.

Surface Preparation
All surfaces to be lined are to be clean, dry, and oil free. Refer to the Application Manual for specific instructions for various surfaces such as concrete,
metal fiberglass, etc.Minimum surface temperature during application – refer to Product Data Sheet.For Brush, Roller, or Spray Applied Products, the surface profile must be 3 mils minimum.
Application Equipment
Brushes – short bristle, nylon, and non-shedding. Replace when products become hot or stiff.

Rollers – short nap (3/8″ max.) non- shedding, with a polyethylene core. Replace when products become hot or stiff.

Plural Only Airless Spray Equipment – Recommendations are listed in the DUROMAR Information and Application Guide.

Do not add solvent to any DUROMAR product. These 100% solids materials are formulated to be applied as shipped after proper mixing.

The temperature of the Hardener (A) and Base (B) portions should be between 70 to 80F (20 to 25C). Mix them separately to insure a uniform consistency.

Add the entire contents of the Hardener (A) to the Base (B) bucket. Use a brush or squeegee to assist in the transfer. These portions are accurately measured and best product performance will be obtained if all the Hardener and Base is combined. Pouring from one container to the other (boxing) during mixing is very helpful in insuring complete mixing

Mix the products until no streaking is observed and then for about one (1) minute longer.

For hand application, immediately break down the full unit into smaller portions such as roller pans, small buckets, or trowel boards. This will keep the product cooler and improve the useable life.

For spray application using a plural component airless system, see Section 4 in the DUROMAR Information and Application Guide. Make sure all components are working according to the airless equipment manufacturers’ instructions and the product components are at the recommended temperature before spraying.

When applying multiple coats of any epoxy products, always check for Amine Blush before applying the next coat. Amine Blush may occur when the epoxy surface is cool or in humid environments. It has the appearance and feel of a light oil film on the surface When dry it has a white chalky appearance. If detected, wash the surface with a 2% hydrochloric acid solution followed by a water wash until the surface pH is between 6-8. Allow to dry before applying the next coat.
Clean Up
Most solvents and commonly used thinners such as MEK, acetone, xylene, I, I, I trichloroethane, and safety solvents such as Ensolv, etc., can be used for cleaning tools and equipment. However, as many of these materials are flammable or present other safety hazards, the user should read the MSDS for these materials before using. In no event should these materials be used to clean material from the skin, eyes or clothing.
Always read and understand the specific product Data and MSDS sheets and the DUROMAR Information and Application Guide before using these High Performance Lining Products.
