Adhesive Primers & Adhesion Promoters

Low surface energy polymers — including HDPE, PTFE (Teflon), polypropylene, nylon, silicone rubber, and Delrin (POM) — require an adhesion promoter before bonding. These materials have inherently slick surfaces that repel adhesives. Tech-Bond's Poly Prep is formulated specifically to etch these substrates and create the surface texture needed for a permanent bond.

No. PTFE and HDPE are among the most difficult materials to bond due to their extremely low surface energy. Applying a bonding agent directly without surface preparation will result in weak adhesion or complete bond failure. Tech-Bond's Poly Prep adhesion promoter is an essential pre-treatment step that chemically etches these surfaces to enable permanent molecular-level bonding.

An adhesion promoter (like Poly Prep) etches the substrate surface to create the right texture and chemistry for bonding. An activator/accelerator is applied to speed up the curing reaction of the bonding agent itself, reducing set time and enhancing final bond strength. In Tech-Bond's system, both components work together as part of the complete Polymer Bonding Process.

Poly Prep is a fast-acting solvent-based formula that dries quickly after application, allowing rapid progression to the bonding step. Exact dry time can vary based on ambient temperature and surface condition, but the formula is designed for efficient, fast-turnaround industrial workflows.

Yes. Poly Prep is available in sizes ranging from 0.75 oz for field repairs up to 5-gallon containers for large-scale industrial use. Volume pricing is available through multi-pack options (5-pack and 10-pack), making it cost-effective for maintenance teams, fabrication shops, and manufacturing operations with recurring bonding needs.

Tech-Bond adhesion promoters and bonding kits are used across mining, pipeline and tank maintenance, automotive, marine and offshore, HVAC, aerospace, agricultural equipment, and municipal water systems. Any industry that works with polymer components — especially HDPE, PTFE, or polypropylene — benefits from Tech-Bond's surface preparation and bonding system.
