Available for download

For many years coatings based on methyl/phenyl silicone resins have proven to be one of the most effective and reliable products within the high heat and protective coatings segments. Their inorganic characters along with the methyl/phenyl modification provide outstanding long term thermal stability, attractive corrosion protection, weather resistance and good mechanical properties. In general, silicone resins for high heat applications can be categorized into two sub-groups: i) oven curing and ii) ambient temperature curing systems.
In the case of typical oven cured silicone

Heat resistance and corrosion protection have been key drivers for the development of methyl/phenyl silicone resins, but current products are limited for high solids, low VOC formulation and longer life cycles. Oven curing silicone binders either use HAP’s solvents or provide limited durability and ambient curing resins require complex combinations of catalyst.
This paper presents a new HAP’s free silicone resin and a novel high solids NISO hardener as solutions for the high heat resistant coatings market where ambient curing and excellent corrosion protection are required. This new hardener is shown to be heat stable and offer improved weatherability and anti-corrosive properties when used together with the latest HAP’s free methyl/phenyl silicone binder and other high solids silicone resins, compared against traditional oven curing systems. The combined performance properties along with the ease of handling and low VOC’s offer the possibility to fulfill the evolving global regulations regarding environment.

In the recent years, Horizontal Directional Drilling - HDD - became a real improvement for pipeline construction when crossing obstacles such as rivers, roads or railways. For the corrosion protection of the carbon steel pipeline, a protective coating is associated with cathodic protection. But for trenchless techniques, the coating shall withstand the stresses from the installation. Several standards are used to specify corrosion protection coatings for buried pipelines but those documents do not cover the specific conditions of an HDD.

The number of CCS projects (planned and in operation) is increasing, and project developers need to provide firm evidence that the proposed material is suitable for these applications.
The petroleum industry has long experience with materials selection for wells, but the conditions for CO2 injection wells are somewhat different from “conventional” oil and gas wells. This is due to the high CO2 content and pressure (up to several hundred bar) which results in low pH condensed water (exact value depends on pressure and temperature, but approximately pH 3.0).

Solid particles entrained in fluids can impact pipelines and equipment causing wear and material removal. Particle impact velocities that are affected by the carrier fluids have the largest effect on the magnitude and distribution of solid particle erosion rates in addition to the mass of impacting particles or the particle rates. In addition to the interaction of particles with the carrier fluids, particles interaction with solid materials makes this process highly complex and produces effects that are interesting and yet important to predict for practical engineering applications.
