Technical Data Sheet 1-C-PUR-Assembly adhesive General Information Paint the bonded workpieces only after the adhesive has cured completely; if they are painted too early, formation of paint bubbles cannot be excluded. If permanent humidity impact is expected, the bonded joints/bonded surfaces must additionally be sealed/protected using a "suitable sealant". Bonding of materials with different longitudinal extension must be assessed regarding their long-term behaviour, especially when they are exposed to fluctuating temperature ranges. The cured mass changes its colour due to UV radiation but...

Technical Data Sheet 1-C-PUR-Assembly adhesive Bonding of wood Bonding of larch: If larch is bonded outdoors, generally 1‑C‑PUR-adhesives may not be used. Substances, included in the wood or possibly generated, e.g. "Arabicum Galactan", considerably destroy/weak the bonding strength . No problems are known for PVAc- and EPOXI adhesives. If solid wood is bonded, the adhesive should preferably be applied on the two surfaces to be bonded. The press pressure shall be >1 N/mm². If solid wood is bonded for outdoor application, perform appropriate tests to achieve optimum bonding depending on wood type,...
