ZOLDINE™ LH-1000 liquid hardener is designed for use with resorcinol-based resins for web-flange (I-joist) and face laminating (glulam) adhesives. ZOLDINE LH-1000 contains less than 0.1% free formaldehyde, helping to minimize the fuming and exposure challenges, as well as expensive engineering controls associated with paraformaldehyde. Use of ZOLDINE LH-1000, in combination with ZOLDINE LH-2001, is intended for applications where fast initial bond development is desired. Because this system advances so quickly, it can only be used where short pot life and assembly times can be accommodated.
