Bonding flexible plastic often requires a specific type of adhesive that can create a strong yet flexible bond capable of withstanding movement and stress without cracking or failing.
Choosing the Right Adhesive
Not all glues are suitable for flexible plastics. Standard rigid adhesives can easily crack or break when the plastic bends, leading to a failed bond. The key is to use an adhesive designed specifically for flexible materials.
According to references, a highly recommended option is Loctite Vinyl, Fabric & Plastic Flexible Adhesive.
Why Loctite Vinyl, Fabric & Plastic Flexible Adhesive?
This specific adhesive is ideal for bonding flexible plastics because of its unique properties:
- Type: Clear liquid adhesive
- Waterproof: Provides a durable bond that resists moisture.
- Dries Clear: Ensures the repair or bond is discreet and aesthetically pleasing.
- Creates a Flexible Bond: Crucially, it maintains flexibility after drying, allowing the plastic to bend without stressing the adhesive line.
- UV/Sunlight Resistant: The bond won't break down or yellow when exposed to ultraviolet light, making it suitable for items used outdoors or exposed to sunlight.
This combination of features makes it particularly effective for repairing items like inflatable toys, vinyl upholstery, raincoats, and other flexible plastic products.
Tips for Bonding Flexible Plastic
Achieving a strong bond involves more than just selecting the right glue. Proper preparation and application are crucial.
Here are some general tips:
- Clean the Surfaces: Ensure the plastic surfaces to be bonded are clean, dry, and free from dirt, grease, or oils. Use a suitable cleaner that won't damage the plastic.
- Test in an Inconspicuous Area: If possible, test the adhesive on a small, hidden part of the plastic to ensure compatibility and desired results.
- Apply Adhesive Correctly: Follow the manufacturer's instructions precisely regarding application method and quantity. For Loctite Vinyl, Fabric & Plastic, a thin, even coat is often recommended.
- Allow Adequate Drying Time: Give the adhesive sufficient time to cure fully according to the instructions before using or stressing the bonded item.
