PRODUCT DESCRIPTION
Liquid, water resistant, polyurethane-based wood adhesive reinforced with fibres. With long open time (1hour) and with limited filling capacity. Marine quality, complies with standard NEN-EN 204: D4.

FIELD OF APPLICATION
For waterproof (D4) (surface) bonding of practically all kinds of wood. Suitable for non-bearing wood constructions with various connections, such as finger joints, dovetails, mortise and tenon joints, dowels and tongue joints. Suitable for indoor and outdoor applications, such as boat construction, facade panelling and sandwich boards. Also for less well-fitting connections (e.g. unplaned wood). Can be applied exclusively if one of both surfaces is porous (strongly absorbent). Not suitable for connections that are subject to a higher, permanent load/tension. For these connections, use Bison Wood Construction Adhesive 2K Expert.
