Bridgewater, NJ - Henkel PURBOND® HB E452 and PURBOND® HB E032 are the world's first and only polyurethane adhesives to pass all tests required for ANSI/AITC 405-2008 certification, the glulam standard. As a result, architects and builders can reap the process, economic, and sustainable benefits of a one-component, polyurethane adhesive.
Created through a joint venture between Collano and Henkel, PURBOND® adhesives offers significant advantages over traditional formaldehyde-based alternatives:
o Engineered open times 3-45 minutes - non coating-weight dependent; o Engineered set time 8-112 minutes - cold set; o One-component system requiring no mixing; o Less adhesive required per square foot, up to 2/3 lower dosage; o 100% solids content, with no formaldehyde or solvents; o No odors, promoting a healthy work environment; o Supports sustainability goals, earns ½ LEED point; o No visible bond lines for an excellent appearance; o Ductile bond line alleviates potential of adhesive-related stress cracks; o Extremely high process reliability, unique temperature and moisture tolerance; o Can bond high moisture-content wood o Excellent bond strength and reliability; o Less wear on milling tools, prolonged tool life.
To achieve ANSI/AITC 405-2008 certification, Henkel PURBOND® HB E452 and PURBOND® HB E032 passed the following ASTM tests:
o D2559 - Structural Load Bearing Standard - Exterior (Wet Use) Exposure (tests shear strength and de-lamination resistance) o D3434 - Boil and dry test (800 cycles) o D3535 - Creep stress test o D1183 - Salt water soak test o D1151 - Frozen water soak test o CSA 01129 - Hot static creep test o D7247 - High temperature test
Purbond is a joint venture between Collano, a Swiss company, and HENKEL KGaA. The two major international adhesives industry players created a Center of Competence to leverage the potential of PUR adhesives technologies for the engineered wood market on a worldwide basis. Its key activities, managed and coordinated in Sempach-Station, Switzerland, are global development, application technologies, and marketing. In 1994, Germany was the first country to approve the use of a 1C PUR adhesive (PURBOND HB 110) for bonding engineered wood components pursuant to DIN 1052. Thanks to its many years of experience, Purbond has established itself as a specialist and leader in this domain. With innovative, high-quality products and world-class technical support, Purbond is the ideal partner for companies that manufacture structural wood elements with moisture-curing liquid polyurethane adhesives.
