During pressing, it is essential to maintain controlled conditions to achieve optimal bonding performance. The loading time should be kept as short as possible—ideally under two minutes—to prevent pre-curing of the adhesive. Apply even and sufficient pressure across the entire surface of the board, ensuring uniform bonding strength throughout; the exact pressure required should be confirmed through practical trials. Additionally, maintain a consistent platen temperature across the press surface, as uniform heat distribution is critical for quality bonding. Timpro PF-40 performs effectively at temperatures as low as 110°C, with higher temperatures allowing for shorter pressing times.
TIMPRO PF-40
Timpro PF-40 Resin, when used in combination with PXF-40 Hardener, is formulated for the manufacture of weatherproof plywood and shutter boards used in the construction industry. This adhesive system forms a bond that meets SABS specifications, producing joints that are insoluble in boiling water, highly resistant to heat, and unaffected by fungi or wood-destroying insects.
The result is a durable, high-strength adhesive ideal for demanding outdoor and structural applications.
Key Features
-
Excellent water and heat resistance
-
Superior bonding strength — stronger than the wood itself
-
Suitable for tropical hardwoods and softwoods such as pine
-
Long shelf life and stable performance in warm climates
-
Easy to clean and handle
MIxing Instructions
Mix Timpro PF-40 Resin and PXF-40 Hardener in the following ratio by weight:
-
Resin (PF-40): 100 parts
-
Hardener (PXF-40): 40 parts
Add the hardener slowly into the resin while stirring to avoid lump formation. Mix until completely smooth and uniform.
The mixed adhesive should be used within 2–3 hours.
-
Unused mix can be incorporated into a fresh batch.
-
If the mixture becomes too thick, the hardener ratio can be reduced by up to 10%.
Veneer Preparation
Timpro PF-40 performs well on both tropical hardwoods and softwoods like pine.
-
Ensure veneers are smooth and well-cut.
-
Veneer temperature before glue application should not exceed 35°C.
-
Optimum veneer moisture content: 7–8%.
