Weld-On® 4784 is a clear, thin to medium bodied solvent cement. It cures rapidly at room temperature resulting in a very strong but flexible bond. Some parts may be handled within a few minutes of application. Bond strength continues to develop very quickly, reaching a substantial level within hours. Joints have similar physical and chemical properties to acrylic plastic and are water and weather resistant.
Some yellowing may occur in high heat, extended sun exposure.
Continuous immersion in water may weaken bond. For prolonged contact with water, use Weld-On 66
The flexibility of Weld-On 4784 makes it ideal for bonding flexible vinyl to itself and several other thermoplastics including cellulose acetate butyrate (trim cap), rigid PVC, acrylic and Kydex® as well as porous materials such as fabrics.
Use when flexibility and weather resistance is preferred to:
