Product description
High quality PVAc adhesive Hranicoll D2 especially suitable for bonding hardwood and resinous wood. It is characterised by a medium time between application and bonding and a high curing speed.
Hranicoll D2 is applied with the common application tools on one or both sides. The coating weight depends on the absorption and the surface conditions of the materials to be bonded. Among others, the temperature, humidity and absorption of the materials, the coating weight and the tension within the material have different influence on the open time, the setting time and the pressing time. Heat accelerates the setting procedure and shortens the open time. Do not apply below +15 °C (room and material temperature).
Avoid contact to iron, colour metal (brass, zinc, tin, copper, aluminium), alkalic materials, tanniferous wood may discolour .
USAGE/EXAMPLE OF USAGE
- bonding hard wood
- onding joints such as chairs and tables
- bonding wood that is difficult to glue
- in operations where special final resistance is required

APLICATION / HANDLING
Wood preparations: work pieces should be properly planed and free of dust and grease. Tolerances cause prolonged setting times and less mechanical strength. You can use any of the common application ways. Before use, mix the adhesive and test all materials intended for bonding to be sure about good results. Make sure that the wood does not contain tannin, such wood may change colour when using Hranicoll D2.Hranicoll D2 is applied with the common application tools on one or both sides. The coating weight depends on the absorption and the surface conditions of the materials to be bonded. Among others, the temperature, humidity and absorption of the materials, the coating weight and the tension within the material have different influence on the open time, the setting time and the pressing time. Heat accelerates the setting procedure and shortens the open time. Do not apply below +15 °C (room and material temperature).
