ISO provides a method of making a visual assessment of the cleanliness of ISO – Rust grades and preparation of uncoated steel substrates. ISO is a pictorial standard relating to surface cleanliness, amongst other methods, though abrasive blasting. The original condition of steel surfaces prior. ISO In updated version of the standard measure for the visual evaluation of rust and purity levels of non-coated steel. Also known as the “ Swedish.

To cope with harsh operating conditions, the material must be strong, durable and robust, where one of the most important characteristics is compressive strength, i. With a high level of tolerance to surface contamination 8501-1 excellent adhesion to manually prepared substrates, Belzona is set to become a preferred choice for emergency repair applications.
Understanding Surface-Tolerant Repairs
Where conventional repair composites are ineffective and perform poorly, Belzona bonds tenaciously onto steel substrates, even when surface preparation is minimal or if the substrate is heavily contaminated with oil or water. The graph below shows the Tensile Shear Adhesion of the system when applied to both grit blasted steel, shown in blue, and ground steel as shown, in 850101, when tested in accordance with ASTM D Unfortunately, meeting all these requirements in the field can often be difficult, especially in offshore and splash zone environments.
A critical aspect of any coating or repair material is its ability to adhere to the substrate. Check out our FAQs.
However, many available polymer repair solutions are not compatible with minimal surface preparation and therefore, can often lead to failure. Light curable adhesives generally require external energy sources; this makes them less desirable from a logistical standpoint. Standby power for marine applications. Adhesives currently available on the market do not tend to perform well when bonding to oil-contaminated surfaces and substrates in wet or aquatic environments, especially at low temperatures.
5801-01 provides excellent adhesion to surfaces contaminated with an extensive range of oils and fuels. Improved production rates, reduced time, as well as the ability to apply materials at lower temperatures 8501-1 extend equipment life are attractive benefits to the coating supplier, applicator, end-user and owner alike.
Belzona provides a cost-effective repair that can reinstate equipment for years of service. At low ambient temperatures, this repair system will still exhibit the same robust, hard-wearing properties synonymous with Belzona technology. Life cycle A standard is reviewed every 5 years 00 Preliminary. Please select your Country: Start typing and press Enter to search.
Emergency situations demand rapid repairs
Monday to Friday – There are instances where surface preparation is an issue 801-01 contamination is common, therefore the substrate cannot be fully cleaned or ideally profiled as required for many repair materials.
Commercial surface-tolerant bonding adhesives are slow to cure and have relatively low bond strengths compared to adhesives formulated for dry applications.
This cold curing system achieves excellent adhesion to manually prepared substrates where grit blasting is not possible. Latest in Belzona TV. Traditional acrylic adhesives have longer set times which slow assembly processes and lower impact resistance, uso in brittle bonds. Unfortunately, meeting all these requirements in the field can often be difficult, if not impossible. Iiso material is effective at displacing contaminants from the substrate via a strong electronic affinity with the metallic substrate, which allows the epoxy to penetrate the profile and create a strong mechanical bond even without grit-blasting.
Surface tolerance Belzona provides excellent adhesion to surfaces contaminated with an extensive range of oils and fuels.

There are instances where surface preparation is an issue and contamination is common, therefore the substrate cannot be fully cleaned or ideally profiled as required for many repair materials. Where conventional repair composites would be ineffective and perform poorly, Belzona bonds tenaciously onto steel substrates even when surface preparation is minimal or if the substrate is heavily contaminated with 8501–01 or water.
New technology in polymeric materials has led to the development of an epoxy-based paste grade product that can be applied onto oily, wet and even underwater surfaces, which eases some of the typical surface preparation requirements. Adhesives currently available on the market do not tend to perform well when bonding to oil contaminated surfaces and substrates in wet or aquatic environments, especially at iao temperatures. One of the major challenges faced by maintenance engineers across many industries is the extremely limited amount of time in which an urgent repair, such as a pipe or tank leak, must be carried out.
Producing faster curing epoxy materials and those curing at lower temperatures have long been goals of protective coatings and repair composites manufacturers. Dolly pull off adhesion.
Surface preparation can be difficult in offshore and splash zones environments. The adhesive strength of the system to ground and grit blasted steel is similar regardless of levels of immersion, contamination and surface preparation.
With isk high level of tolerance to surface contamination and excellent adhesion to manually prepared substrates, Belzona has become a preferred choice for emergency repair applications. Pin It on Pinterest.
This article focuses on the latest epoxy technology of a new two-component paste grade material which achieves a quick, durable repair also in oil contaminated, cold, wet and underwater areas.
Latest technology development Several market-driven requirements have been identified for a fast curing product with surface tolerance.
