For parts which are exposed to the weather, however, with appropriate surface protection. Due to its high heat resistance particularly suitable e. g. for segmented profiles, window scantlings and window edges. For the bonding of wood and wooden materials, bonding of joints in boards and block gluing of soft wood, hard wood (after preliminary tests) and surface bonding. FOLCO LIT D4 W91 is a highly water resistant wood adhesive which corresponds to the durability class D4 according to DIN EN 204. Good heat resistance: > 7 N/mm² according to DIN EN 14257 (WATT 91).
