HRANITHERM 10.390 LC Natural - PUR Hot Melt
Description du produit
Polyurethane reactive hot melt natural adhesive Hranitherm 10.390 PUR LC (Low Content) with very low isocyanate emission for edge banding with good thermal stability and high green strength. The cross-linked adhesive joint shows excellent final strength, resistance to humidity and good flexibility at low temperatures. Available also in white colour (Hranitherm 10.391 PUR LC).
- high green strength
- clean machining
- easy processing due to controlled reactivity
- high heat resistance and cold flexibility after crosslinking
- it is suitable for edge banding machine with glue pot for granules
USAGE
- gluing ABS, PVC and PP edges with primer
- gluing impregnated papers, HPL/CPL
- gluing solid wood, veneer edges

APPLICATION / HANDLING
Suitable for edge banding machines with melting pot. When using the hot melt adhesive, check the application temperature on a regular basis by measuring on the roller or nozzle. The temperature shown on the edge-banding machine control panel may differ from the actual temperature. Lower temperature of the adhesive may affect its open time and consequently impair the bonded joint quality. At a higher temperature, the adhesive may degrade, which affects its colour, viscosity, and adhesion. When banding edges from various materials, regular testing of banding strength and quality is advisable. Recommended temperature of the environment and materials is 15 – 25°C.
CLEANING
Clean not-crosslinked residual adhesive on furniture elements using Hraniclean 01 (08). In the melting system use PUR-cleaner 890 in cartridge or granules (blue colour) for flushing the glue out, PUR-cleaner 892 HL for cleaning of the crosslinked glue. You find more information of these cleaning agents in their TDS.
PRECAUTIONS FOR SAFE USING
Even under normal conditions of use product may produce hazardous vapours which may cause a respiratory tract irritation. Provide adequate ventilation. Before use read the SDS of the product.
STORAGE
1 kg package of mini-cartridges in aluminium foil. Shelf life is 12 months from the production date in optimal storage conditions (cool and dry; 15 - 25°C) in intact packaging. Storing at temperature above 30°C may cause increase of viscosity. An opened package can be stored in nitrogen atmosphere, or in a special equipment with dry air or in a fridge with temperatures from -10°C to -18°C, maximum 1 week.
