Waterproof D4 rating for moisture resistance
Works on wood, MDF, metal, and insulation panels
Expands slightly to fill gaps
Solvent-free and low odor
Ideal for furniture, packaging, and construction applications
Applications: Thermocol Bonding, Furniture, Construction & More
1K PUR adhesive is widely used for thermocol bonding in insulation panels and packaging. In furniture making, it bonds wood, MDF, and laminates securely. In construction, it fixes insulation boards, panels, and decorative elements. It is also used in automotive interiors, signage, crafts, and general industrial assembly where strong, waterproof bonding is required.
Supex 7150 also serves as an effective thermocol glue. It joins both porous and smooth surfaces with ease. Moreover, it sticks firmly to wood, MDF, fiberboard, particleboard, metal, laminates, stone, ceramic, brick, foam, fiberglass, marble, plasterboard, masonry, rubber, and some plastics.
It works great on edge-to-edge joints, I-beam joints, sandwich panels, tropical woods, and building parts like doors, windows, and pillars. Therefore, this flexibility makes it a trusted pick for pros.
How to Use 1K PUR Adhesive – Step-by-Step Guide
Ensure surfaces are clean, dry, and dust-free
Apply 1K PUR adhesive in a thin, even bead
Join parts immediately and align properly
Press or clamp surfaces for firm contact
Allow adhesive to cure and expand slightly
Remove excess after curing if required
Avoid disturbing the joint during setting
Store adhesive in a cool, dry place
Clean Finish and Easy Use
After curing, the 1K PUR adhesive forms a glue line that you can sand, paint, or stain without trouble. Consequently, it suits visible joints and fine woodworking where looks matter.
How This PUR Adhesive Works
Supex 7150 cures by reacting with moisture from the air or materials. The moisture starts the process, and then it builds a strong, cross-linked structure. In addition, this gives a firm yet flexible bond that mixes speed with solid strength.
FAQs
Q1: What is 1K PUR wood adhesive?
It is a single-component polyurethane adhesive that cures with moisture to form strong, durable bonds for wood and other materials.
Q2: What materials can it bond?
It bonds wood, MDF, plywood, laminates, thermocol (EPS), foam, metal, and insulation boards.
Q3: Is it waterproof?
Yes, it offers D4-grade waterproof resistance, suitable for indoor and outdoor applications.
Q4: Does it expand during curing?
Yes, it expands slightly, helping fill small gaps and improve bonding strength.
Q5: How fast does it set?
Initial setting occurs within 10–20 minutes; full curing takes up to 24 hours.
Q6: Does it damage thermocol?
No, it bonds EPS thermocol without melting or deforming it.
Q7: How should it be stored?
Store in a cool, dry place with the cap tightly closed to prevent premature curing.
It offers the perfect answer for those who want reliable bonding, simple application, and long-term trust from a quality PUR adhesive.
