This high-performance adhesive is known for its structural bonding capabilities, making it an ideal choice for many applications, including aerospace, automotive, construction, and electronics.

In this article, we will explore the features and benefits of 3M Scotch-Weld Epoxy Adhesive DP420NS, the factors that influence its price in Bangladesh, its availability, and how it compares to other similar products in the market.

What is 3M Scotch-Weld Epoxy Adhesive DP420NS?

The 3M Scotch-Weld Epoxy Adhesive DP420NS is a two-part structural adhesive that cures at room temperature. It is designed to bond a wide variety of materials, including metals, plastics, glass, ceramics, and composites. The product is particularly valued for its high strength, excellent durability, and superior resistance to impact, vibration, and environmental stress.

Key Features of DP420NS:

1. High Strength Bonding: DP420NS offers excellent shear and peel strength, making it suitable for structural applications that demand high strength.
2. Non-Sag Formula: The adhesive has a non-sag formula, meaning it won’t drip or run during the application, even on vertical surfaces.
3. Excellent Gap-Filling Properties: The product can fill gaps between bonded substrates, improving bond integrity.
4. Wide Temperature Range: DP420NS can withstand temperatures between -40°F to 250°F (-40°C to 121°C), making it reliable for use in extreme conditions.
5. Clear Appearance: It dries clear, which is an added advantage for aesthetic or cosmetic applications.

The “NS” in the name refers to the non-sag characteristic of this adhesive, indicating it is particularly suitable for applications where the adhesive needs to stay in place without running or dripping during the curing process.

How is 3M Scotch-Weld Epoxy Adhesive DP420NS Used?

The applications of 3M Scotch-Weld Epoxy Adhesive DP420NS are vast and varied. It is often used in industries where high-strength, durable bonding is critical. Some of the primary industries and applications include:

• Automotive: DP420NS is used to bond automotive components such as bumpers, dashboards, panels, and other structural elements. It is ideal for both interior and exterior bonding.
• Aerospace: The adhesive is employed for bonding lightweight composites, metals, and other materials in aircraft manufacturing and repair.
• Electronics: It is used to bond parts in electronic devices that require a strong, durable, and thermally stable bond, such as in computer hardware, mobile phones, and appliances.
• Construction and Architecture: DP420NS can be used for bonding materials like glass, metal, and concrete, making it suitable for both interior and exterior construction applications.
• Marine and Defense: The adhesive is used in bonding materials used in the manufacture of boats, ships, and defense-related structures, where impact resistance and environmental stability are essential.

The versatility and robustness of 3M Scotch-Weld Epoxy Adhesive DP420NS have made it a popular choice in these industries.

Price of 3M Scotch-Weld Epoxy Adhesive DP420NS in Bangladesh

The price of 3M Scotch-Weld Epoxy Adhesive DP420NS in Bangladesh can vary based on several factors. These include the supplier, quantity purchased, shipping or importation costs, local taxes, and availability.

1. Factors Influencing Price

• Supplier and Distribution Network: The price of industrial adhesives like DP420NS may differ depending on whether the product is purchased through local distributors or international suppliers. Local suppliers may offer the product at slightly higher prices due to the inclusion of import duties, taxes, and shipping costs.
• Quantity Purchased: The price per unit tends to be lower when purchased in bulk. Manufacturers, large construction firms, or companies requiring large quantities of adhesive may receive a discounted price compared to smaller businesses or individuals buying in smaller amounts.
• Shipping and Import Fees: Since 3M products are typically imported into Bangladesh, the cost of shipping and any applicable import taxes can significantly influence the final retail price. Changes in global shipping rates and supply chain disruptions can also affect the pricing.
• Local Availability and Stock Levels: Availability plays a role in the price as well. If the product is in high demand but in short supply, prices may increase. Conversely, if there is a surplus of stock, prices might be lower.
• Currency Fluctuations: Fluctuations in the exchange rate between the Bangladeshi Taka (BDT) and the US Dollar can also impact the price. Since many international manufacturers price their products in USD, any shift in the currency exchange rate can influence the final retail price in Bangladesh.

2. Estimated Price Range

As of recent estimates, the price of 3M Scotch-Weld Epoxy Adhesive DP420NS in Bangladesh can range from BDT 3,000 to BDT 5,000 per 50 ml cartridge, depending on the above-mentioned factors. Larger quantities or bulk purchases may bring down the cost per unit. However, due to the import nature of the product and its specialized use, the cost of Scotch-Weld Epoxy DP420NS can be relatively high compared to other local adhesives.

For larger quantities, such as cases of 12 or more cartridges, buyers may see a price reduction. For example, the price could fall to BDT 2,500 to BDT 4,500 per cartridge if purchased in bulk. As always, buyers are encouraged to inquire with local suppliers for specific pricing and bulk discount options.

3. Comparing Prices with Similar Products

When comparing the price of 3M Scotch-Weld Epoxy Adhesive DP420NS to other similar structural adhesives available in Bangladesh, it is clear that while DP420NS is on the higher end of the pricing spectrum, its performance justifies the cost. Some alternative adhesives, including locally manufactured products or other international brands, may be priced lower but may not offer the same level of strength, durability, or environmental resistance.

Some common alternatives to 3M Scotch-Weld DP420NS include:

• Loctite Epoxy: Loctite, another trusted name in the adhesive industry, offers several epoxy adhesives with similar properties. These adhesives are generally priced lower than the 3M product but may not offer the same high-performance results.
• Araldite Epoxy: Araldite is a well-known brand that offers a wide range of epoxy adhesives. While generally more affordable, the performance may vary, and they may not match the non-sag, high-strength qualities of DP420NS.
• Local Epoxy Adhesives: Various local manufacturers in Bangladesh produce epoxy adhesives for general use. These adhesives are typically lower in price but may not meet the specific needs of industrial applications requiring structural bonding and resistance to environmental stresses.

In terms of pricing, 3M Scotch-Weld Epoxy Adhesive DP420NS may be more expensive than these alternatives, but the cost is justified for professional, high-performance applications where reliability, longevity, and strength are paramount.
