Foreword to Chapter 3 Polyurethane Adhesives and Sealants

Polyurethane is the fastest growing chemical family in the adhesives and sealants industry, as polyurethanes enjoy a very versatile chemistry One or two components, chemical curing, humidity curing or PUR reactive hotmelts, flexible, elastomeric or rigid adhesives, sealants, and potting compounds. All kinds of adhesives and sealants may be formulated with numerous different PU, polyols and isocyanate raw materials. 

Polyurethane chemistry and adhesives and sealants is such a large and important topic that several chapters will he spent covering this subject A general chapter in Volume 1 (written by a team of scientists from Loughborough University in the UK), PU sealants in Volume 3, PU flexible adhesives and sealants by Sika in Volume 2 and again in Volume 5 probably, and PU adhesives for laminating and packaging in Volume 4 by Bostik-Findley. 

Readers (chemists, engineers, designers) from the various industries, and suppliers of adhesives, sealants, raw materials should read these chapters.
