How to use Eva primer?

EVA Primer EV80F is a specialized two-component primer designed for treating various EVA (Ethylene Vinyl Acetate) materials. It is used in conjunction with hardener F306 or F309, depending on the color of the material. This primer stands out due to its excellent treatment effect and ease of use, eliminating the need for roughing and irradiation treatment.

Key Features

• Two-Component System: Requires mixing with hardener F306 (or F309 for white materials).

• No Toluene: Safe and environmentally friendly.

• No Roughing Needed: Simplifies the preparation process.

• Excellent Treatment Effect: Ensures strong adhesion and durability.

Steps to Use EVA Primer EV80F

Step 1: Prepare the Mixture

Before using EVA Primer EV80F, add 5-10% of hardener F306 to the primer and mix well. For white materials, use hardener F309 instead. This step ensures that the primer is activated and ready for application.

Step 2: Clean the Surface

Ensure that the surface of your EVA material is clean. Use a damp cloth to remove any dirt or debris. A clean surface guarantees better adhesion of the primer.

Step 3: Apply the Primer

Using a brush or cotton cloth, evenly apply a thin layer of the mixed primer onto the EVA material. Make sure to cover the entire surface uniformly.

Step 4: Drying Process

Place the primed material in an oven set at 55±5°C for 2-4 minutes. This drying process helps in forming a strong bond between the primer and EVA material.

Step 5: Apply Adhesive

Once dried, proceed by applying your chosen adhesive evenly over the primed surface. Ensure there are no gaps or accumulations in adhesive application.

Step 6: Final Bonding

After applying adhesive, follow these steps:

1. Heat treat at 60±5°C for 3-5 minutes.

2. Press and bond as required.

Tips for Effective Use

1. Use Within Time Limit: Once mixed with hardener, use within four hours to ensure optimal effectiveness.

2. Ventilation: Always work in a well-ventilated area to avoid inhalation of fumes.

3. Protective Gear: Wear gloves and masks during application to protect skin and lungs from potential irritation.

4. Storage: Store both components in cool, dry places to extend their shelf life.

5. Follow Instructions: Adhere strictly to manufacturer’s guidelines for best results and safety.

Conclusion

EVA Primer EV80F simplifies the preparation process by eliminating roughing requirements while ensuring excellent adhesion properties on various EVA materials when used correctly with its corresponding hardeners (F306 or F309). By following these steps and tips, you can achieve superior bonding results for your projects involving EVA materials.
