The fourth edition includes advances in knowledge that have taken place most recently. The new data and the information are integrated with information in previous edition to form consistent up-to-date analysis of the most important findings. In many instances new findings make previous understanding obsolete. The revision is based on the analysis of over 2000 research papers published since the previous edition. This book raises many questions but also helps to find answers.
The following aspects of weathering and degradation are extensively discussed in the book:
Use
Coverage
Theory
two chapters on photophysics and photochemistry
Stress factors
full analysis of effects of radiation, temperature, water, oxygen, pollutants, and stress as well as their combined actions
Methods of measurement
Full chapter on methods of measurement of stress factors (radiation, sunshine duration, temperature, relative humidity, time of wetness, rain, pollutants) Full chapter on methods of weathered sample testing. Forty groups of methods discussed and illustrated with examples of application to sample analysis.
Climatic conditions
A chapter analyzing ranges of stress factors, theirs averages and extreme values for climatic conditions on all continents
Methods of weathering
Separate chapter on subjects listed below: - Sample preparation - Methods of outdoor exposures - Methods of laboratory exposures - Weathering cycles - Lifetime prediction - Laboratory vs. outdoor exposure
Weathering effect
The most important changes in materials properties are discussed in fundamental manner: on materials (mass loss, degradation depth, mechanical performance, optical properties, color, surface, molecular weight, chemical composition, morphology)
Weathering of polymers
Over forty groups of polymers and rubbers are discussed to formulate mechanism of degradation, effect of thermal processes, present characteristic changes in properties, and tables of available numerical data
Weathering of products
Over thirty groups of products are discussed to define their requirement related to durability, lifetime expectation, relevant degradation mechanisms, and important changes
Additives and weathering
A chapter discussing effect of ten groups of processing additives on weathering performance of materials
Stabilization
A chapter on methods of material stabilization and currently best selections of stabilizers
Biodegradation
Formulation of materials to prevent biodegradation and chemical methods of prevention
Environment stress
cracking A chapter discussing parameters controlling ESC, mechanisms, process kinetics, effect on materials, and methods of testing
Specific topics
Separate chapters on subjects listed below: Production of materials with recycling in mind Interrelation of corrosion and weathering Degradation, testing, and prevention of deterioration of stones in historical monuments
With this amount of information, clearly organized and explained, this book is an important reference monograph for those involved in studying material durability, producing materials for outdoor use and actinic exposure, research chemists in the photochemistry field, chemists and material scientists designing new materials, users of manufactured products, those who control the quality of manufactured products, and students who want to apply their knowledge to real materials. The book aims at providing comprehensive, up-to-date information on weathering thus reducing the time for searching for answers in many different sources. Previous editions are used in more than 60 countries as reference source of information on weathering. Last ten ears produced twice as many papers than the total number of papers included in the first two editions. These important new findings change how we approach various aspects of weathering today.
From reviews of previous editions: George Wypych's handbook helps enormously in providing us with a single source on material weathering....This work is not simply a formalized handbook of material damage. The early chapters are quite didactic and would provide students with interesting introduction to photochemistry, environmental, and weathering conditions and the evaluation of weathering....This is really worthwhile book for anyone whose interest in the weathering of materials goes beyond metals and stone.
P. Brimblecombe, Atmospheric Environment
Anyone needing a broad, well-referenced review with a lot of discussion of real products will find this a valuable resource. It can certainly be recommended highly.
N.C. Billingham, Polymer Degradation and Stability
This is more than a handbook on weathering of materials...Highly recommended
G. Epstein, Composite & Adhesives
