Spray-Dried Urea Resins

LRBG Chemicals spray-dried urea resins are used in a wide range of adhesive applications such as hot and cold-pressed plywood and particleboard, edge gluing veneers, and tapeless splicers. Unlike traditional liquid urea formaldehyde resins, our resins are supplied in a powder form for improved shelf life and for more flexibility in formulating adhesives.

BTLU RW-25 A neat (unfilled) uncatalyzed adhesive and binding resin that is suitable for a variety of applications. Used with wood, cellulosic substances and foundry sand. The resin can be cured using just heat or a catalyst can be added to shorten the cycle time. The catalyst content can be increased to give a cold cure wood clue.
BTLU MW51 An unfilled, uncatalyzed resin suitable for use in applications where a low viscosity, highly reactive resin is required. This resin can be cured with the addition of catalysts, or in many instances, the acidity of the substrate is sufficient to cure the resin. The low viscosity of the resin makes it suitable for use with a variety of fillers and extenders.
BTLU 250-S A pre-catalyzed and filled ready mix urea resin used in cold press application. Popular with plywood and particleboard manufacturers and can also be used for panels, edge gluing and some decorative lamination. This resin can be used where a visible glue line is no problem.
BTLU 253 A pre-catalyzed, neat (unfilled), ready-mix urea resin. Used in wood bonding such as particle-board, fiberboard and chip core or where a lighter line is desired.
