What is an adhesive?
An adhesive is a substance capable of holding materials together
by surface attachment. Note: adhesive is a general term and includes among
others cement, glue, mucilage, and paste. All of these terms are loosely
used interchangeably. Various descriptive adjectives are applied to the
term adhesive to indicate certain characteristics as follows: (1) physical
form, that is, liquid adhesive, tape adhesive, etc.; (2) chemical type,
that is, silicate adhesive, resin adhesive, etc.; (3) materials bonded,
that is, paper adhesive, metalplastic adhesive, can label adhesive, etc.;
(4) condition of use, that is, hot setting adhesive, room temperature
setting adhesive, etc.

What is a pressure sensitive adhesive?
A term commonly used to designate a distinct category of adhesive
tapes and adhesives which in dry (solvent free) form are aggressively
and permanently tacky at room temperature and firmly adhere to a variety
of dissimilar surfaces upon mere contact without the need of more than
finger or hand pressure. They require no activation by water, solvent
or heat in order to exert a strong adhesive holding force toward such
materials as paper, plastic, glass, wood, cement and metals. They have
a sufficiently cohesive holding and elastic nature so that, despite their
aggressive tackiness, they can be handled with the fingers and removed
from smooth surfaces without leaving a residue.

What is a sealant?
According to ASTM a sealant is defined as "in building construction, a material which
has the adhesive and cohesive properties to form a seal."

What is a joint sealant?
Joint sealants are used to seal joints and openings (gaps) between
two or more substrates, and
are a critical component to building design and construction. Learn
more about joint sealants.
What markets use adhesives and sealants?
Adhesives and sealants are used in a variety of markets and supplied
in many different product forms.
Where can I find basic information about raw materials and additives
that are used in adhesive and sealant formulations?
ASI magazine's Raw Materials, Chemicals and Additives Handbook
is published annually and provides descriptions for a comprehensive list
of raw materials, chemicals and additives used in the manufacture/formulation
of adhesives, sealants, pressure sensitives, tapes and labels. These useful
definitions include information about applications and uses of the products.
Access
the ASI Raw Materials, Chemicals and Additives Handbook and
scan down to the "Select a definition" search box. Click on
the down arrow to access a menu of raw material and additive options.
How can I access a directory of ASC Members who supply raw materials
and additives, adhesives and sealants, and other professional services?
ASC maintains an Online Directory
of Manufacturers and Suppliers. Select the type of product (or service)
you are interested in researching, and click on the yellow square to access
a list of ASC Members who provide the corresponding product or service.

Bonding/Adhesives Textbook | FEICA Educational Materials
Bonding has become an indispensable technique not only in industry but
also in everyday life. Bonding allows the production of laminated materials,
facilitates mobility and communications, positively influences the handling
of foods, supports health and hygiene and improves the quality of our
lives. Moreover, many innovative products could not be manufactured without
the use of bonding techniques. FEICA's Educational Materials series textbook
entitled "Bonding/Adhesives" offers numerous examples.
Other Recommended Reference Books
EPA's
Emission Scenario Document on Adhesive Formulation
This EPA document provides information on the sources, use patterns and
potential release pathways of chemicals used in the formulation of adhesives.
The document presents standard approaches for estimating the environmental
releases of and occupational exposures to additives and components used
in adhesive formulations. These approaches are intended to provide conservative,
screening-level estimates resulting in release and exposure amounts that
are likely to be higher, or at least higher than average, than amounts
that might actually occur in the real world setting.
Launched in 2008 by the ASC, adhesives.org is an online educational portal dedicated to engineers, designers, architects and others who wish to understand the benefits and advantages adhesives and sealants bring to modern product design and assembly. This web portal has been designed to help improve awareness about the benefits and value of the industry's products, and help clear up misperceptions. Here you can access a variety of information on such topics as:
TRAINING PROGRAMS
ASC Short Courses and Webinars
ASC offers a comprehensive schedule of Technical Short Courses and Webinars to suit your needs. Most short courses are co-located with our conventions, except Fundamentals of Adhesion Science (held every even year) and Additives (held every odd year), which are stand-alone. Webinars are typically an hour to 90 minutes in length and feature live instruction with interactive Q&A.
Online Training: An Introduction to Adhesives, Sealants and Adhesion Science
Courtesy of Virginia Tech
This series of online training modules form an introductory-level course
designed to train employees new to adhesive and sealant science. The online
education program enables students to view the lecture materials (available
with audio and streaming video) at their office or home computers, at
their own pace when their schedules permit. Learn
