KLEIBERIT 501.0 1K PUR Adhesive D4 brown

What is KLEIBERIT 501.0 1C-PUR Adhesive D4?

KLEIBERIT 501.0 is a versatile, single-component polyurethane adhesive for heavy-duty and moisture-resistant D4 bonds. This PUR adhesive is suitable for wood and wood-based materials, as well as for numerous mineral and porous materials.

With an open time of approximately 20–25 minutes, KLEIBERIT 501.0 provides sufficient processing time for demanding assembly, surface, and structural bonding. The adhesive reacts with moisture and cures to form a durable, yellowish-brown bond line.

The available variants are based on container size and quantity. This allows for individual containers, practical tiered quantities, and full packaging units to be selected directly.

Application Instructions

• Surfaces to be bonded must be clean, stable, dust-free, and free of grease, oil, or other separating residues.
• At least one of the two parts to be joined should be sufficiently absorbent or moisture-permeable.
• For very dry materials, slight moistening can support the reaction of the PUR adhesive.
• Apply the adhesive evenly and sparingly to one of the surfaces to be joined.
• Join the components within the open time and press sufficiently or secure firmly.
• Due to the moisture-induced reaction, the adhesive may foam slightly during curing.
• Remove excess adhesive, if possible, before complete curing, according to the manufacturer's instructions.
• Before serial applications or with sensitive materials, perform a test bond.
• Observe the technical data sheet, safety data sheet, and processing instructions on the container.

What does stress group D4 mean?

Stress group D4 according to DIN EN 204 describes wood bonds with particularly high moisture resistance. This includes applications in indoor areas with frequent and long-lasting water exposure, as well as suitable constructions in outdoor areas.

The D4 classification refers to the bond line. The entire component must be designed structurally and with suitable surface protection for the respective outdoor application.

Difference from KLEIBERIT 501.6 and 501.8

KLEIBERIT 501.0 is the universal version of the 501 series of PUR adhesives and offers a medium open time of approximately 20–25 minutes.

• KLEIBERIT 501.6: Long open time for large-area or complex bonding
• KLEIBERIT 501.8: Short open time for fast assembly and production processes

Due to their different processing properties, the products are managed as separate parent articles.

Frequently Asked Questions

Which materials is KLEIBERIT 501.0 suitable for?

The PUR adhesive is suitable for wood, wood-based materials, mineral building boards, ceramics, concrete, and rigid foam, among others. At least one of the parts to be joined should provide the necessary moisture for curing or be sufficiently absorbent.

Is KLEIBERIT 501.0 ready to use?

Yes. It is a single-component PUR adhesive that is processed without the addition of hardener.

Do the components need to be clamped during curing?

Yes. The workpieces must be held together with sufficient pressing force or otherwise securely fixed during curing.

Does KLEIBERIT 501.0 foam?

The adhesive reacts with moisture and can foam slightly. Sufficient pressing pressure reduces foam formation in the bond line and ensures a strong connection.

Is KLEIBERIT 501.0 suitable for outdoor applications?

The cured bond line meets D4 according to DIN EN 204. However, the component itself must still be designed structurally and with suitable surface protection for the respective outdoor application.

Which container size should I choose?

The 0.5 kg bottle is suitable for repairs, smaller projects, and regular individual applications. The 6 kg canister is intended for professional users with higher, recurring material requirements.

What quantity tiers are available for the 0.5 kg bottle?

The 0.5 kg bottle is available as a single item, as a tier of 6 bottles, and as a complete packaging unit of 12 bottles.

Where can I find safety and manufacturer information?

Processing, hazard, and safety instructions can be found on the product container, the technical data sheet, and the manufacturer's safety data sheet. The structured manufacturer information is also maintained with the product.
