Engineered Polymer Solutions for Industry

In Tech-Bond Global's context, EPS refers to the Engineered Polymer Solutions product category — a complete system of bonding kits, surface preparation agents, activators, and fillers designed to permanently bond difficult polymers like PTFE, HDPE, Delrin, and silicone rubber. This is distinct from expanded polystyrene foam, which shares the EPS acronym in other contexts.

Tech-Bond products are engineered to bond materials traditionally considered unbondable, including PTFE (Teflon), HDPE, Delrin (POM), polypropylene, nylon, silicone rubber, and low surface energy plastics, as well as metal, wood, and composites. The correct kit — Poly Prep surface prep, bonding agent viscosity, and accelerator — must be selected based on the specific substrate.

Starter and Basic Kits provide the core bonding agent in three viscosities for general maintenance and repairs. Deluxe Kits add an Accelerator, Poly Prep, and Filler for technician-grade work. Professional Kits include the full system — bonding agent, Poly Prep, Activator/Accelerator, Filler, and Debonder — engineered for permanent high-strength bonding of Delrin, PTFE, HDPE, and composite assemblies.

SI Blue is a thin-to-medium standard viscosity suitable for general bonding tasks. SI Black is a thicker formulation providing greater control for precision or overhead applications. SI Green is ultra-thin and specifically designed to wick into and repair hairline cracks. Selecting the correct viscosity is critical to achieving the strongest, most reliable bond for your specific repair.

Yes, for low surface energy polymers such as PTFE, HDPE, nylon, and polypropylene, Poly Prep is an essential pre-treatment step. It etches the polymer surface to create the right texture for molecular adhesion. Skipping this step on difficult substrates will significantly reduce bond strength. Poly Prep is fast-drying and available in sizes from 0.75 oz to 5 gallons.

All Tech-Bond bonding agents and kits should be stored in a refrigerator to achieve the longest possible shelf life. Before use, bring the product back to room temperature. Poly Prep, being solvent-based, should be stored in a cool, dry place per standard safety guidelines. Proper storage ensures consistent performance across every application.
