PVC Bonding Adhesives

For a permanent bond, first apply Poly Prep to etch the PVC surfaces and promote adhesion. Then apply the appropriate SI Bonding Agent (Blue for standard, Black for controlled application, or Green for hairline cracks) followed by the Activator/Accelerator to catalyze the bond. This three-step Polymer Bonding Process creates a molecular-level connection between the two PVC pieces.

Technically possible but not recommended for a lasting bond. PVC has low surface energy, which prevents most adhesives from achieving strong adhesion without preparation. Tech-Bond Global's Poly Prep adhesion promoter etches the PVC surface to create the ideal texture for the SI Bonding Agent, significantly increasing bond strength and durability compared to skipping this step.

Choose based on your application: SI Blue (thin-medium) works for general-purpose PVC bonding; SI Black (thick) provides greater control for precision or overhead bonding tasks; SI Green (ultra-thin) is designed specifically for repairing hairline cracks in PVC surfaces. All three viscosities are available across Tech-Bond Global's starter, basic, poly, and professional kits.

Yes. Poly Prep is Tech-Bond Global's dedicated adhesion promoter for polymers including PVC. It is a fast-drying solvent-based formula that etches the surface to create optimal texture for bonding. It is available in sizes from 0.75 oz to 5 gallons and is included as a component in the Professional Kit and Deluxe Kit selections.

Yes. Tech-Bond Global offers volume and bulk pricing across multiple kit sizes, with options ranging from small single kits up to large-quantity configurations exceeding $1,700. Products are used in mining, energy, marine, aerospace, HVAC, and infrastructure sectors globally. The Professional and Industry Kits are specifically designed for technicians and commercial operations.

All SI Bonding Agent kits — including Starter, Basic, Poly, Deluxe, and Professional Kits — should be stored in a refrigerator to maximize shelf life. Before use, bring the product back to room temperature. Poly Prep (adhesion promoter) should be stored in a cool, dry place as it is a solvent-based formula.
