Test report No.: 505 25079/2 Technical Data Basis Colour hard-dry Skinning time - dry at +20 °C, 50 % r. H., applied quantity 500 μm-PE/PVC Skinning time - wet at +20 °C, sprayed with water; applied quantity 500 μm-PE/ PVC Curing time at +20 °C, 50 % r. H. until ~75 % Curing time at +20 °C, 50 % r. H. until it reaches the final strength Functional strength depending on application at +20 °C Applied quantity depending on carrier material Processing temperatures adhesive and substrates 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". Weiss Chemie + Technik GmbH & Co. KG Hansastraße 2 D-35708 Haiger

Technical Data Sheet 1-C-PUR-Adhesive 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 not its strength in the cured bonded joint. Caution: the viscosity of the 1‑C‑PUR adhesives is approximately twice as high at +15 °C as at +25 °C. Skinning, joining times, as well as the required press and following processing times can only be determined accurately by selftests because they depend on material, temperature,...

Technical Data Sheet 1-C-PUR-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, weathering...
