Polymer Adhesives | Types, Uses & Solutions

Tech-Bond products are specifically engineered to bond low surface energy and traditionally unbondable polymers including HDPE, PTFE (Teflon), Delrin (POM), polypropylene, nylon, silicone rubber, and more. The Poly Prep adhesion promoter prepares these surfaces for maximum bond strength before applying the SI Bonding Agent.

Yes — for low surface energy polymers like HDPE, PTFE, and silicone, surface preparation using Poly Prep is essential. This solvent-based adhesion promoter etches the surface to create the right texture for molecular bonding. Skipping this step on difficult substrates will significantly reduce bond strength and durability.

The three variants differ in viscosity. SI Blue is a thin-to-medium standard viscosity suited for general bonding. SI Black is thicker, providing greater control for precision or overhead applications. SI Green is ultra-thin and designed specifically for penetrating and repairing hairline cracks where standard viscosities cannot reach.

Starter Kits are ideal for general maintenance and household use. Basic Kits suit mechanics, handymen, and farm equipment repair. Deluxe Kits are built for professional technicians needing full repair capability. Professional Kits offer the complete bonding lifecycle — including Debonder — for engineers and industrial settings. Industry Kits address taxidermy, solar, and prep room applications specifically.

Yes. The Debonder is a precision-grade solvent designed to dissolve and remove cured bonding agents without damaging most substrate materials. It can be used for rework, accidental over-application cleanup, disassembly of incorrectly bonded joints, and tool or skin cleanup. Immersing bonded joints in acetone may also achieve full separation over time.

All SI Bonding Agent kits should be stored in a refrigerator for maximum shelf life. Before use, bring the product back to room temperature to ensure optimal viscosity and performance. Poly Prep, a solvent-based product, should be stored in a cool, dry place away from heat sources and in accordance with standard solvent safety guidelines.
