FIRM BOND PUR adhesive is a humidity curing 1 component adhesive based on polyuerthane, it expands slightly during the curing process and gives exceptionally strong bonds on virtually all materials.
1. For all types of woodwork, to replace white wood glue.
2. For Window and door bonding, staircase assembly, plywood for internal and external use ( external with surface protection ), bonding of mineral building materials, ceramic materials, concrete materials and hard foams.
Features & Benefits
Boling water resistant conforms to DIN EN 204/D4
High temperature resistance as per WATT91
l Application temperature ideal at +20ºC, do not use below +5ºC.
l Moisture content of wood ideal at 8-10% internal areas, and 10-14% for window assembly
l Coat weight 100-200g/m2 depending on material
l Open time
Approx 20-25min at 20ºC. High room temperature and high air hunidity or adding of moisture will reduce this time
l Press time
At+20ºC approx. 60 min
At+40ºC approx. 30min
l Final bond strength
After approx.24hr if the humidity supply is sufficient
Instruction of Use
1.The surfaces must be acclimatised,dry, clean and free from dust and grease;
2. Apply this adhesive only on one surface, bond the surfaces;
3. Press the surfaces together.
l Requires a pressure of minimum 0.6N/mm2 for plywood and joint bonding.Directly adding moisture or high temperature will speed up the cross linking process.
l The bonded parts can be processed after approx.2-3 hrs if sufficient moisture was added.
l Wipe off any surplus adhesive immediately with a cloth.
l Clean tools immediately after use. Cross linked adhesive can only be removed mechanically.
