3. Use Cases and Industry Examples

3.1 Automotive Industry Use Cases

Customer Pain Points:

Silicone seals under the car hood require bonding to metal frames. Standard adhesives often fail at high temperatures, leading to oil and air leaks.

Solutions:

Use ND-608CP for metal surface pretreatment followed by hot pressing and peroxide vulcanization.

Application Effects:

•         The product passed the high-temperature aging test at 200°C.

•         Stable bond strength and extended service life by 50%

•         Perfect substitute for imported adhesives; costs reduced by 20%

•         After-sales return rate dropped below 0.1%

3.2 Kitchenware and Baby Products Case Study

Customer Pain Points:

The silicone spatula handle is bonded to either phenolic resin or stainless steel. It must meet food-grade standards and ensure a secure bond, as standard adhesives pose safety risks.

Solutions:

Surface treated with ND-608CP and vulcanized using peroxide curing.

Application Effects:

•         Non-toxic and odorless at the bond; meets food-grade standards.

•         The silicone body does not detach during tensile testing, even when pulled to the point of breaking.

•         SGS certified

•         Customer satisfaction increased to 98%

4. Detailed Usage Guide

Preparation for 4.1 operation

Tools and Materials Required:

•         ND-608CP Hot Vulcanization Adhesive

•         Cleaning cloth or lint-free cloth

•         Industrial alcohol or specialized cleaning agent

•         Adhesive applicator (brush or spray gun)

•         Oven or hot air equipment

4.2 4-step process

Step 1: Surface Treatment

•         Sandblast or sandpaper the metal or plastic substrate

•         Clean and degrease using industrial alcohol to remove surface oil and impurities.

•         Ensure the surface is dry, clean, and free of dust.
Critical: The surface must be clean and oil-free to ensure proper adhesion.

Step 2: Apply adhesive

•         Ready to use right out of the box—no mixing required.

•         Apply evenly to the prepared substrate surface by brushing or spraying.

•         Coating thickness should be controlled between 0.05 and 0.1 mm.

•         Ensure even coverage with no missed areas.

Step 3: Drying

•         Store in a cool, dry place:Let stand for at least 30 minutes

•         Hot Air/Bake:Suggest baking at 100-120°C for 5-15 minutes (more efficient)

•         Hot air drying is recommended to significantly improve production efficiency.

Step 4: Vulcanization

•         First vulcanization:Suitable for double 2,5-bisulfide systems

•         Two-Stage Curing:Do not exceed 200°C. Gradually increase the temperature for optimal performance.

•         Curing time is determined by product thickness and process requirements.

4.3 Important Notes

•         Ensure the operating environment is well-ventilated.

•         Avoid direct skin contact; wear protective gloves if necessary.

•         Keep away from heat sources. Do not store in high temperatures.

•         Not suitable for children

V. Frequently Asked Questions (FAQ)

5.1 Product FAQs

Q1: Is ND-608CP a two-component product? Does it require mixing before use?

A: Absolutely not! The Ningdao ND-608 series isSingle-componentGlue: Ready to use right out of the bottle, eliminating bonding failures caused by inaccurate mixing ratios in two-part adhesives.

Q2: Can silicone bonded to metal undergo two-stage oven curing?

A: Absolutely. This product is designed for hot vulcanization and can withstand二段硫化 temperatures up to a maximum of...200℃adhesion strength does not decrease and becomes even more stable.

5.2 Storage and Shelf Life

Q3: What is the shelf life? How should it be stored?

A: Shelf life is valid when stored in a cool, dry place at 20°C to 25°C, unopened.3 monthsThis product contains solvents and is volatile. PleaseSeal and store。

Q4: Can leftover glue be used the same day if not all of it was applied?

Apply adhesive and bond as soon as possible. If storage is necessary, ensure the coated surface remains uncontaminated. For unused adhesive, store it separately from used adhesive to extend its shelf life.

5.3 Technical Support

Q5: Do different substrates require different treatments?

A: Yes, different substrates require different surface treatment processes:

•         Metal substrate: Recommended to sandblast and then clean with alcohol.

•         Plastic substrate: Clean with specialized cleaner after sanding

•         Ceramic substrate: dried after ultrasonic cleaning
