LORD® 459X adhesion enhancer/surface modifier is designed for promoting adhesion to rubberized plastics (aka thermoplastic elastomers) (TPE) and thermoplastic polyolefins (TPO). The Hard to bond plastics.
LORD 459X adhesion enhancer/surface modifier can be used with many types of adhesives, including MMA's (acrylics), urethanes, polyurethanes, and epoxy structural adhesives, as well as with a variety of double-sided tapes.
Lord 459X is similar to another primer the Lord 7701, but they work with slightly different types of rubber & soft plastics. Here's a comparison between LORD 459X and LORD 7701, both of which are adhesion enhancers/primers for improving bonding to low surface energy materials — especially rubbers and rubber-like plastics.
Which Should You Use?
- Choose LORD 459X if you're bonding:
-
Thermoplastic Elastomers (rubber-like plastics). Polyolefins (Low Surface Energy / Hard-to-bond Plastics)
-
Examples include:
-
| TPE Type | Description | Typical Use |
| TPE-S (Styrenic block copolymers) | Easy to process, low cost | Grips, soft-touch handles |
| TPE-O (Olefinic TPEs) | Good for automotive, lightweight | Car interiors, bumpers |
| TPE-U (Thermoplastic polyurethanes - TPU) | High abrasion & tear resistance | Sporting goods, cables, seals |
| TPE-V (Vulcanizates) | More rubber-like, heat-resistant | Under-the-hood car parts |
| TPE-E (Thermoplastic copolyester) | Excellent fatigue and chemical resistance | Automotive belts, gears |
-
Choose LORD 7701 if you're bonding:
-
Rubbers, either natural, vulcanized or synthetic (EPDM, NBR, NR, etc.)
- Soft Flexible forms of PVC (often used on flooring)
-
-
Choose Either One Lord 458X or Lord 7701 if you're bonding:
- Soft rubbery plastics (Thermoplatic Elastomers (TPEs))
- Examples are Vulcanized Plastics (plastic-rubber blends)
- TPO / TPE-O Thermoplastic Polyolefins (blended PO's with rubbers)
- TPU / TPE-U (rubbers blended with polyurethanes)

| Surface Prep Required | Clean (degrease) before use | Clean, possibly abrade depending on the substrate |
| Dry Time |
30 minutes at room temperature 5-10 minutes if headed to 200-250F |
5-10 minutes at room temperature (as soon as primer dries/evaporates it is complete and ready to bond)

| Common Applications | Bonding rubber gaskets, seals, bumpers, and isolation pads | Automotive TPO bumpers, interior trim panels, or plastic housings |
Shelf Life
Shelf life is six months from date of shipment when stored at 21-27°C (70-80°F) in original, unopened container.
Avoid storage in lit areas. Store only in original container or UV-filtering plastic or glass container. Do not store in metal containers. Store LORD 7701 surface treatment in a cool, dark area away from oil, grease, sawdust, floor sweepings, easily oxidized organic compounds, ammonia, amines, ammonia salts, and metallic materials. Do not pollute with water or alcohol. In the event of a spill, use large quantities of water to flush the area.
Features and Benefits
- Works with various rubbers / vulcanized, thermoset, and thermoplastic polymeric materials like HDPE, LDPE, MDPE, LLDPE, PP, and EPDM
- Versatile – functions as a cleaner and surface conditioner; treats a wide variety of elastomer functional materials.
- Optimized for MMA glues.
- Easy to Apply – applies easily by wipe, brush, dip or flood methods.
- Convenient – requires no mixing.
- Improved Adhesion – improves adhesion to cast urethanes and cured rubber.
- Fast Drying – adhesion enhancer/surface modifier flashes off within five minutes or less.
- Environmentally Resistant – promotes increased environmental resistance by allowing the treated surface to be more easily wet.

Storage
Store LORD Adhesion Enhancers/Surface Modifiers should in theiroriginal containers. When transferringto another container, only transfer the amount needed for the application. Do not return unused material to the original container as this will cause pollution. LORD 7701 cannotbe stored in metal containers orbe used with metal acid brushes as this will cause the material to precipitate white particles. Keep all
LORD adhesion enhancers/surface modifiers (except LORD 459T or 459X) in a cool, dark and dry area.
