Which domestic adhesive manufacturer is better for substitution? Comparison and selection guide of domestic adhesive brands

2026-03-09

In recent years, with the changing international trade situation and the increasing awareness of domestic supply chain security, the domestic substitution of adhesives has become a focus of attention for more and more enterprises. Although imported brands have mature technology, they face problems such as long supply cycles, high prices, and slow response times. Domestic adhesive manufacturers are rapidly rising due to their cost advantages, stable supply, fast response, and customized services. Yilian system analyzes the differences between domestic adhesives and imported brands, recommends reliable adhesive manufacturers, and helps enterprises achieve efficient domestic substitution. Lithium battery cell encapsulation1、 Why choose domestic adhesive manufacturers? Domestic substitution is the trendAdhesive, as the “monosodium glutamate” in industrial production, is widely used in various fields such as automobiles, electronics, new energy, packaging, and construction. According to industry data, the Chinese adhesive market accounts for 32% of the global market, ranking first in the world, and is expected to have a compound annual growth rate of 8% in the future. However, the high-end adhesive market has long been monopolized by international giants, and there is huge room for domestic substitution. Four reasons for the rise of domestic adhesive manufacturersSupply security and stabilityInternational brands are affected by factors such as trade wars, exchange rate fluctuations, and import cycles, resulting in supply uncertainties. Domestic manufacturers produce locally, with short supply cycles and sufficient inventory. Significant cost advantageDomestic adhesive prices are usually 20% -40% lower than imported brands, which can significantly reduce procurement costs for enterprises and enhance product competitiveness. Quick technical service responseDomestic manufacturers can provide faster technical support, on-site service, and problem response, while imported brands often have longer response cycles and higher communication costs. Flexible customized servicesDomestic manufacturers can customize products and optimize formulas according to specific customer needs to meet personalized application scenarios, which…

Why do electronic components need potting? How to choose different types of potting compound?

2025-12-25

Today, as electronic products continue to develop towards high reliability and integration, encapsulation has become an indispensable process in many electronic systems. Whether it is automotive electronics, power modules, industrial controls, or LED lighting, component encapsulation is widely used. But in practical engineering, some people still often ask: why do components need to be sealed? How to choose different types of sealant? Understanding these two issues is an important prerequisite for doing a good job in the reliability design of electronic products.Battery thermal conductive sealing adhesiveBattery thermal conductive sealing adhesiveChallenges faced by electronic components in real-world application environmentsComponents often operate stably under laboratory testing conditions, but in practical applications, they need to face long-term temperature changes, moisture intrusion, mechanical vibrations, and complex electrical stresses. High and low temperature cycling can cause thermal expansion and contraction of materials, and humid environments may lead to corrosion of solder joints and pins. Continuous vibration can accelerate solder joint fatigue. When these factors exist alone, their impact is limited, but in long-term operation, they often overlap and become the main cause of component failure.Why do electronic components need to be sealedThe primary function of sealing is environmental protection. After curing, the sealing adhesive forms a continuous and dense protective layer, which can effectively block water vapor, dust, and chemical pollutants, preventing performance degradation caused by moisture and corrosion. This is particularly crucial in outdoor equipment, automotive electronics, and industrial sites.Next is to enhance electrical safety. In high-voltage or high-frequency applications, the spacing between components continues to shrink, increasing the risk of creepage and discharge. Sealing adhesive has stable electrical insulation performance, which can fill gaps, evenly distribute electric fields, and improve the insulation reliability of the system.Sealing can also reduce the risks caused by mechanical vibration and impact. During the operation or transportation of…

The multifunctionality of single component epoxy adhesives: applications, advantages, and key considerations

2025-05-15

In modern manufacturing, adhesives are no longer just adhesive materials, but also one of the core processes for improving product reliability, durability, and protective performance. Especially in high-precision industries such as electronics, electrical, automotive, and new energy, higher requirements have been put forward for the performance of adhesives. Single component epoxy adhesive is a pre mixed epoxy resin system that does not require manual mixing and can be quickly cured by heating. It is suitable for various industrial applications such as automated production, precision manufacturing, electronic packaging, and structural bonding. 1、 What is a single component epoxy adhesive? One component epoxy adhesive is a pre mixed epoxy resin system at the factory, which does not require secondary mixing by the user and can be used directly. It is usually cured by heating. This type of adhesive is stable when stored at room temperature for a long time, and only reacts quickly at a certain temperature to form a high-strength structure. Compared with traditional two-component adhesives, single component products greatly simplify the operation process, avoid human proportioning errors, and improve production efficiency, especially suitable for automated dispensing, sealing, or coating systems. 2、 The core advantages of single component epoxy adhesive ✅ 1. Convenient operation and efficient production No need for weighing and mixing, ready to use, greatly reducing the operating threshold and working time, especially suitable for assembly line operations and automation equipment, can significantly improve unit production capacity. ✅ 2. Fast curing, adjustable control Most products are cured by heating (such as 80 ℃/30 minutes or 120 ℃/10 minutes), and the curing window can be flexibly set according to the actual production cycle, supporting efficient batch processing. ✅ 3. Strong adhesion and wide applicability Epoxy system has excellent polarity and excellent adhesion to various substrates such as metals, ceramics, glass,…
