Adhesives for wood
Wood-based panels such as OSB, LDF, and particleboard are fundamental to today’s construction and furniture industries. Alongside wood, polyurethane adhesives are a key ingredient in their production.
Polyurethane Adhesive for OSB, LDF, and Particleboard
Polyurethane adhesives are commonly used in the manufacture of particleboard, OSB, and LDF panels. Typically, single-component products are more frequently used, while two-component adhesives are less common. Both types belong to Puroxen’s system solutions.
A single-component adhesive already contains mixed components, while a two-component adhesive requires their combination. To create the adhesive, the following are needed:
- Polyols
- Isocyanates
This prepared adhesive reacts with moisture from the environment to create a very strong, durable bond that is resistant to various factors.
Wood Adhesives (HMW Type)
The polyurethane adhesive for LDF, OSB, and particleboard belongs to the HMW group. It is intended for hot forming, which is the best method for producing durable wooden panels. This process requires:
- Single-component polyurethane adhesive
- Wood chips or fibers
- Steam
Under high temperatures and with the aid of a press, sheets are produced that are used in constructing many frame structures and also as a crucial element in furniture (including upholstered furniture). The entire process takes place at temperatures above 100°C with the involvement of steam.
| Puroxen HMW for wood | Wartość |
| Content % NCO | 9,0 – 11,0 |
| Viscosity [mPas] | 150 – 650 |
| Density [g/m³] | 1,1 – 1,3 |
Polyurethane Adhesive for Wood Replaces Carpentry Products
The same high-quality polyurethane adhesive can be used for the production of boards made from small chips, large rectangular pieces, and fiberboard. This allows for the desired hardness, durability, and flexibility of the panels.
Polyurethane adhesive can, and should, be used for joining wooden elements. Vinyl or rubber-based adhesives do not provide sufficient durability. Hot-formed polyurethane adhesive offers significantly better properties, and once cured, it is as safe as traditional carpentry products.
Product Technologist
In our research and development department, we have created advanced polyurethane adhesives that are crucial for the production of wood-based panels such as OSB, MDF, and particle boards. We offer one-component adhesives tailored to the requirements of the Puroxen systems.
Our wood adhesives (HMW) are ideal for producing durable and long-lasting panels that find extensive application in construction and furniture manufacturing. Through precise research and innovative solutions, our products provide excellent hardness, flexibility, and durability, replacing traditional carpentry products.
