If you’ve worked in an industrial setting, you’ve likely encountered silicone adhesives and sealants. These versatile products come with a range of properties designed to meet different application needs.

Silicone Adhesives vs. Sealants

• Silicone Adhesives
  Made from silica (found in quartz sand), silicone adhesives are used to bond two substrates together.

• Silicone Sealants
  Best for filling gaps and joints, offering flexibility and durability once cured.

Note: Unlike some adhesives, silicone products require curing—a process that can be time-consuming but essential for long-term performance.

How Long Does Silicone Take to Dry?

• Touch-Dry Time: 30 minutes to 1 hour

• Full Cure Time: Usually 24 hours, but may take several days depending on temperature, humidity, and product type.

Tip: Always allow for full curing before putting the bonded material to use.

✅ Do’s of Using Silicone Adhesives and Sealants

1. Use a Primer

Primers help the sealant adhere better to surfaces. Apply with a brush, cloth, or spray gun, and follow the manufacturer’s instructions.

2. Consider Shelf Life

Store silicone products in a cool, dry place. Avoid opening them until needed, and always check the expiration date before use.

3. Prep Your Substrates

Clean surfaces thoroughly (often with isopropanol) and ensure they are dry before applying the adhesive or sealant.

4. Apply Pressure When Needed

For materials like metal, use a clamp or vise to hold surfaces together during curing to ensure a strong bond.

5. Apply with Precision

Silicone is hard to remove once cured. Use tools like a sharp knife or cheese wire for removal if needed. Apply carefully to avoid mistakes.

❌ Don’ts of Using Silicone Adhesives and Sealants

1. Don’t Choose Without Research

Select the right product for your material.

• Example:

  • ASI 335 Neutral Cure – Best for engines, oil pans, and transmissions

  • ASI 57 Modified Polyurethane – Ideal for bonding metal, mortar, or wood

2. Don’t Use Expired Products

Expired silicone can be harder to work with and form weaker bonds. Always check the expiration date.

3. Don’t Skip Surface Preparation

Dirt, oil, and residue can prevent proper bonding. Clean and dry surfaces are critical for success.

4. Don’t Ignore Instructions

Every silicone product has specific curing times, mixing requirements, and substrate compatibility. Always read the instructions to avoid mistakes.
