Weld On 4 Cement 4oz

Product details

Weld On 4 Cement 4oz is a water-thin, solvent-cement designed to bond acrylic (poly-methyl methacrylate) to itself. In practical aquarium-shop terms, it’s useful for solvent-welding compatible plastic parts and assemblies where a clear, strong bond is important—especially when working with acrylic displays, panels, and other thermoplastic fabrication that benefits from solvent-fusing rather than mechanical fastening.

Features:

• Bonds acrylic (poly-methyl methacrylate) to itself for strong, solvent-welded joints
• Also forms strong bonds with other thermoplastics (polystyrene, CAB, and polycarbonate) to themselves
• Blush-resistant: helps reduce the chance of white marks (often called blushing) compared with some alternatives
• Water-thin cement that softens the surfaces first, then fuses them together
• Initial bond forms within minutes, with bond strength continuing to increase over the next several hours
• Not recommended for cross-linked acrylic
• Commonly used in fabrication workflows such as butt joints with the soak method and capillary-method assembly
• Used across many thermoplastic assembly applications, including display/presentation case fabrication and plastic container bonding

Specifications:

• Product form: Water-thin cement (solvent-based)
• Bonding targets: Acrylic to acrylic; polystyrene to polystyrene; CAB to CAB; polycarbonate to polycarbonate
• Compatibility note: Not recommended for cross-linked acrylic
• Color/appearance: Formulated to be blush-resistant (helps reduce white marks)
• Cure/bond development: Initial bond within a matter of minutes; continued strength increase over several hours
• Package size: 4 oz
