Weld-On Solvents

Weld-On solvents deliver reliable bonds for acrylic projects. These acrylic cements join plastic parts with clarity and strength. Fabricators trust them for displays, signage, and custom builds. At Tucson Plastics, we stock popular formulas to match your needs.

Fast-setting action saves time on assembly lines.
Clear finish keeps designs sharp and professional.
Low-VOC options support safer workspaces.

Product Overview

Weld-On solvents stand out in plastic bonding. They dissolve surfaces for a fused joint, not just glue. This creates seamless connections ideal for acrylic sheets, rods, and tubes. Our selection covers thin to medium viscosities for precise work.

Widely used for

Bonding acrylic to acrylic in fabrication shops.
Assembling point-of-purchase displays.
Sealing edges on architectural panels.

Repairing prototypes in R&D labs.

Performance Characteristics

High bond strength exceeds 5,000 psi on cured joints.
Quick set times from 1-5 minutes, depending on formula.
Resistant to water, mild chemicals, and UV exposure.
Easy application with brushes, syringes, or daubers.

Types and Formulations

Choose from clear, low-odor versions or heavy-bodied for gaps. We carry Weld-On 3 for thin joints and Weld-On 16 for thicker fills.

Modern two-component, low-VOC structural formula.
Ultra-clear, DCM-free (no methylene chloride), low-odor cement.
High-viscosity gel that stays exactly where you put it.
Flexible and UV-stable formula built for outdoor Arizona sun.
Slightly thicker than #3 with a slower evaporation rate.

Can Weld-On solvents bond other plastics?

Best for acrylic-to-acrylic. Test on polystyrene; avoid PVC or ABS without compatibility checks.

How do you apply Weld-On solvents?

Use in a well-ventilated area. Apply with a brush or syringe. Clamp parts for 1-2 minutes. Full cure in 24 hours.

Are Weld-On solvents safe for indoor use?

Yes, with ventilation. Low-VOC types reduce irritation. Wear gloves and goggles; follow SDS guidelines.
