New-Type Environmental-Friendly Coumarone Modified Furan Resin (Bleached Asphalt) Coating (Paint)

(Another Name: Benzofuran Furan Resin Paint, Furan Bleached Asphalt Coating)

Ⅰ. Brief Introduction to Products

New-Type Environmental-Friendly Coumarone Furan Resin (Bleached Asphalt) Coating (Paint): coumarone resin is produced by processing coal pitch and carrying out catalytic polymerization. The coumarone resin comes from catalytic polymerization of the fraction with boiling range of 160-200℃ obtained in the process of tar distillation. New-Type Environmental-Friendly Coumarone Furan Resin Coating (Paint) is produced from the reaction of coumarone resin and furan resin. In this way, the excellent performance of furan resin is kept and other performance of furan resin is also improved, including flexibility, shock resistance and adhesion. Without carcinogen and other substances that will do harm to the human body, it has the excellent features of high thermal resistance, anti-corrosion, waterproofing, resistance to acid and alkali, good insulativity, strong adhesion, etc. In addition, its anti-aging period can last more than 50 years in normal environment. This coating has two components: A and B, and it has been put into production for commercial supply.

Ⅱ. Product Features   

    1. The coating has excellent performances of waterproofing, insulativity, resistance to acid and alkali, oil resistance, damp resistance, soil resistance and chemical resistance.

2. This coating has good adhesion, flexibility and resistance to alternation of moisture and dryness and can strongly resist the corrosion of microbe and plant roots.

3. With two components, the coating can be coated thickly for one time and solidified in low temperature. It is easy to be used at site.

Ⅲ. Applicable Scope

It is mainly applied to resist the corrosion of the following equipments such as outer surface of underground pipeline for oil and water, inner and outer surface of storage tank, sewage treatment equipments, water ballast tank and cargo hold of ship and oil platform, slop tank, water line and bottom of ship and offshore platform, gas storage tank, harbor, quay and sluice gate.

Ⅵ. Construction Instructions

1. Pls refer to construction specifications and standards in the pipeline anti-corrosion engineering handbook: for metal surface treatment, it is preferable to derust by sandblast. The derusting quality shall reach Sa2.5 grade prescribed in GB/T8923 and the depth of anchor pattern should be about 30μm. The surface of the concrete shall be free from dust, oil, moisture, alkali and the treated surface shall be coated with the primer within 24 hours.  

2. Coating preparation: before being used, the component A shall be stirred fully and then the component B shall be added. They shall be mixed in the proportion of 1:0.5-1 by weight, and painting shall start after the mixture is fully stirred and cured for 10-20 minutes; the prepared coating shall be used up within 1 hour. If it has high viscosity, the ethanol shall be added as the diluent, but the usage amount shall not be more than 3-5%.

3. With suitable consistence and good placeability, this product provides simple operation and easy application. Application of this coating is prescribed in detail in the China national standard GB 50268－97 Code for Construction and Acceptance of Water Supply and Sewerage Pipelines, China oil &gas industrial standard SY/T 0447－96 Standard of Coal Tar Epoxy Coating for Buried Steel Pipeline, and China petrochemical industrial standard SH 3533-2003 Specification for the Construction and Acceptance of Piping Works for Water supply and Drainage in Petrochemical Industry, and the construction method and acceptance specifications shall observe the existing Technical Specification of Furan Resin Anticorrosion Engineering CECS 01:1988, Construction and Acceptance Specification of Architecture Corrosion Protection Engineering GB 50212-2002.

Ⅶ. Product Package

For New-Type Environmental-Friendly Coumarone Furan Resin Coating, component A is packed in the barrel (net weight: 30-230kg/barrel); component B, curing agent, is packed in bags (net weight: 25 kg/bag).

Ⅷ. Notes

1．            Coumarone Furan Resin Coating is combustible; therefore, it shall be put in a dry, ventilated and cool place and prevented from rain and sunlight exposure or from being close to the fire; its transportation shall follow safety requirements of combustibles transportation.

2．            In order to guarantee the coating quality, construction of anticorrosion coating in the open air shall be stopped in the event of sand storm, rain, snow, and fog. It is not suitable to construct when the surrounding temperature is below 5℃ or above 40℃, or when the relative humidity is over 80%.

3．            The coated equipment can be delivered to use after the coating is cured completely and the maintenance period shall be 28 days at 20℃ to guarantee the project quality.

4．            Storage period of this product is 1 year; during this period, even if precipitate is found in the barrel, the product can still be used after being fully mixed. The product beyond the storage period can be tested according to technical indexes; if the indexes can meet the requirements, then the products can still be used.
