JOWAPUR 687.40 — PUR Prepolymer

Usage:

• bonding of hard wood species, compounds elements
• bonding of compounds of HPL/CPL
• bonding to galvanized iron or metals
• bonding expanded polystyrene (sanded) to wood, stone etc.
• also used at ship/boat constructions

Characteristics:

One-component adhesive Jowapur 687.40 based PU prepolymer in light-brown appearance of the adhesive film without solvent and formaldehyde has good adhesion to many materials and high strength values. The adhesive Jowapur 687.40 cures with air humidity. It complies with the resistance class D4 according to DIN EN 204/205.

Application:

Before using Jowapur 687.40, it is advisable to perform self-testing, the properties of the materials and the processing conditions affect the bonding. The adhesive is usually applied on one side of surface. A spatula or roller is used to application. For non-absorbent materials and wood moisture below 8 %, the adhesive film or adhesive material should be lightly moistened with a spray. For moulding it is good to treat the press with a separating agent. We recommend using paper when the adhesive leaks.

Bonded larch wood needs to be protected from direct contact with water.

We recommend cleaning the adhesive from application tools by Hraniclean 03 (non-hardened adhesive) or Hraniclean 04 (hardened adhesive).

For detailed information see the Technical and Safety Data Sheet.

Packaging and storage:

Store in the original packaging in a dry and cold place for a period indicated on the label at temperatures of +15 to +25 °C. During transport the temperatures may be lower, from +6 to +14 °C, but the material may be exposed to these temperatures for a max. duration of 14 days. Cold material may not be processed, but must be previously warmed up slowly, about 2 to 3 days depending on the size of the package. Open packs can be further processed.
