Silicone Sealant OEM FAQ: Custom Formulations for Middle East

B2B Guide | OEM & Custom Formulation

This silicone sealant OEM FAQ addresses why ordinary sealants struggle to withstand high-temperature thermal shock in the tropical desert climate regions of the Middle East. When you see the sealant on a project crack or fall off prematurely, it is because it cannot adapt to the local climate conditions. Contractors in the Middle East all choose silicone sealants with strong weather resistance; however, weather resistance performance and curing time vary greatly. Very few engineering projects will spend time slowly testing which product works well. Choosing a sealant specifically developed for the hot and dry climate of the Middle East can save a lot of trouble for the project. For OEM silicone in Middle East projects, custom formulation is the most important thing. This blog post mainly introduces how to customize OEM silicone sealant formulations for your Middle East projects.

1. Why Standard Silicone Sealants Cannot Work in the Middle East

This is due to the special curing principle of silicone, which needs to absorb moisture from the air to undergo a chemical reaction and produce curing. The Middle East region, especially Dubai and Saudi Arabia, experiences continuous high temperatures and extreme dryness all year round. This condition is not conducive to the normal curing of sealants. The surface of the colloid dries rapidly when encountering high temperatures, while the interior does not have enough moisture for the crosslinking reaction. This unreasonable curing state causes the sealant to easily crack and have poor adhesion, which is also the reason why ordinary sealants can be applied in other regions, but perform with major headaches in Saudi Arabia.

2. Customizing Silicone Formulations for Your Middle East Projects

Professional sealant manufacturers develop custom formulations according to local climate conditions. When WEIDU was developing specialized curtain wall sealants for the Middle East region, R&D personnel collected data on-site in the UAE, Saudi Arabia, and other regions, and then moved the laboratory to the local site to do experiments. Initially, we found that strong summer UV rays quickly destroyed the sealant strip polymers. After adding heat-stabilizing fillers and crosslinking agents, the curing speed could not reach the ideal effect. In order to make the formulation perfectly suitable for the tropical desert climate, the WEIDU R&D team used equipment in the laboratory to simulate local climate conditions. After a full year of data monitoring and on-site verification, our one-component and two-component sealants are fully capable of being applied in the Middle East market, maintaining good resilience and adhesion on high-rise glass curtain walls in Dubai without chalking or cracking over decades of outdoor exposure.

3. How to Customize OEM Silicone Sealant Formulations

Formulation customization is not as simple as merely increasing or decreasing a certain raw material. Adjusting any single indicator will affect the overall performance of the entire sealant. For example, increasing the curing speed alone will affect extrudability and adhesion. A professional formulation adjusts the entire chemical system so that the overall performance of the sealant reaches the expected target.

In regions such as Dubai and Riyadh, summers are hot while winters have low temperatures and low humidity. A single formulation is difficult to apply to different seasons; in particular, the curing speed is difficult to predict, and the colloid is prone to sagging. WEIDU’s flexibility is reflected in our ability to adjust custom formulations for each batch, precisely controlling tack-free time and non-sag performance.

Every batch of customized products is supported by WEIDU’s internal R&D laboratory, and our R&D Director has over 20 years of experience in the field of chemical materials. As a leading structural silicone sealant manufacturer, we never blindly try formulations, but conduct scientific R&D based on rigorous laboratory data, accelerated aging tests, and strict project technical specifications. Different areas of a building facade need to use sealing products with specific chemical structures. We tailor professional solutions according to your specific application scenarios. For microclimate environments in coastal or humid areas (such as coastal development projects in Jeddah or Doha), we can provide customized solutions with high hardness or anti-mold functions.

4. OEM Custom Formulation Process

1. Before obtaining an OEM quotation, we will learn from you the detailed information of the project’s application scenarios, compatible substrates, curing system, color, packaging, etc. If you can provide a product TDS or sealant sample, we will quickly provide you with a quotation.
2. After WEIDU receives the sample, we conduct test analysis, and then carry out formulation adjustment and testing. The tests include adhesion, tensile properties, hardness, curing behavior, elastic recovery, weather resistance, and compatibility.
3. Accurately calculate the quotation according to the formulation grade, quantity, packaging, and shipping method, and simultaneously provide the client with the product TDS report.
4. After the formulation adjustment is completed, samples are made and sent to the client, and the client confirms the performance of the sample: adhesion and extrudability, curing speed, color, packaging, and specifications.
5. The OEM order enters the production schedule.
6. Before OEM products leave the factory, every batch of products undergoes strict inspection, including tensile strength, elongation at break, and butterfly tests, to ensure that the bulk cargo quality is consistent with the sample.

In Middle East projects, color is also a customization content that all contractors care about. The WEIDU team will confirm the RAL color code with the client, and then carry out sample color debugging. After the sample color is confirmed by the user, we proceed with bulk cargo production, ultimately ensuring that the bulk cargo color is consistent with the sample color.

For distributors in the UAE and Saudi Arabia, customized packaging helps create a unified brand image across different product categories. Clients can also customize the following content:

1. Product labels and cartridge body design.
2. Private label packaging for local distribution: Carton printing and packaging specifications.
3. Brand logo and product name.
4. Color and product code.

In the UAE and Saudi Arabia, glass curtain walls are widely used in commercial buildings, hotels, shopping malls, and high-rise building projects. These sealing systems are exposed to direct sunlight, high temperatures, wind loads, and building displacement for a long time. Weatherproof sealants must be able to maintain reliable performance for a long time, and structural silicone sealants must meet specific mechanical property and adhesion performance requirements. Every formulation determines the long-term performance of the product, including: adhesion force, UV resistance and weather resistance performance, movement capability, tensile strength and elongation performance, mechanical strength, and material compatibility.

5. Choosing a Reliable OEM Manufacturer

When some manufacturers receive OEM orders, they may change the packaging of a standard product formulation and sell it to the client. The benefit of doing this is to promote the rapid closing of the order through a low-price formulation, which reduces R&D costs for the factory. However, the true value of a tube of sealant is the long-term value it brings in a construction project, though in reality nobody will be bored enough to wait eight or ten years to feed back the results. Professional sealant manufacturers, like WEIDU, have always insisted on making custom formulations, because a long-lasting enterprise takes responsibility for the results, and the value of the brand coexists with the long-lasting value of the sealant.
