Knuffi Surface and Corner Protection Bumper Guard Type S (Ref: KTI16007002TY0S) is engineered for fast, reliable application along high-risk internal transport routes, structural profiles, machinery zones, and pedestrian corridors. The integrated high-performance, light- and aging-resistant self-adhesive backing ensures durable surface adhesion across industrial facilities without the need for mechanical fasteners, drilling, or bracket hardware.
Substrate Preparation and Surface Cleaning
Achieving optimal adhesive bond strength requires meticulous substrate preparation. The mounting surface—whether structural steel, painted industrial metal, flat concrete, or machinery framing—must be completely dry, dust-free, and grease-free before positioning the profile.
Remove all surface contaminants, oil residues, moisture, and particulate matter using a suitable industrial solvent or degreasing cleaner. Ensure that the cleaned substrate is fully dry and residue-free before exposing the adhesive strip to prevent adhesion compromise.
Custom Sizing and Field Cutting
Supplied in standard 1 m lengths with a 75x25 mm cross-section profile, Type S guards weigh between 0.8 kg and 1.10 kg per piece. The body is manufactured from CFC-free flexible polyurethane (PU) foam with a Shore A hardness of 40, protected by a reverse counter-printed outer foil layer.
When custom lengths are required for pillars, machine edges, or specific partition spans, the profile can be cut cleanly on-site using a standard utility knife. Cut through the foam core and outer foil with a firm, continuous stroke. Straight, 90-degree cuts allow multiple 1 m sections to be mounted end-to-end with flush, continuous seams across extended internal transport routes.
Step-by-Step Self-Adhesive Mounting Process
- Step 1: Alignment Check: Dry-fit the 1 m Type S profile against the targeted edge or surface to verify alignment and clearance.
- Step 2: Liner Separation: Peel back a starting segment (approximately 50 to 100 mm) of the protective release liner from the high-performance adhesive backing.
- Step 3: Initial Placement: Position the exposed adhesive firmly onto the prepared substrate at the exact starting point.
- Step 4: Continuous Application: Gradually pull the remaining release liner downward while smoothing the 75x25 mm profile along the application line.
- Step 5: Final Pressure: Apply uniform, firm manual pressure across the entire length of the polyurethane profile to ensure complete adhesive contact and eliminate air voids.
Operational Environmental Parameters
Once bonded, the aging-resistant self-adhesive mounting system maintains operational performance within extreme industrial temperature environments ranging from -40 °C to +100 °C. The material complies with fire classification standards DIN 4102 B2 and UL 94 HB / 10 mm. When planning layout schemes, install profiles in accordance with BGV A8 and ASR A1.3 safety marking guidelines using the available visual schemes: yellow/black hatching, red/white hatching, solid black, or solid white.
