Ability of an adhesive to resist degradation due to mechanical wear by hard and
rough objects (mechanical erosion) thanks to the ability to dissipate the
applied mechanical energy.
Syn. Vulcanizing agent
Compounding material used in small amounts with a vulcanizing agent to increase
the speed of vulcanization.
Additive neutralizing and absorbing hazardous acid spills.
Made by the polymerization of acrylic monomers, such as ethyl acrylate and
Acrylonitrile Butadiene Styrene resin,
Common polymer (plastic) with high resistance to heat, low-temperatures and
impact, and exibiting excellent surface appearance. Bonds well with many
Chemicals which can be applied directly to a surface, substrate or mixed with
an adhesive to speed up the solidification of an adhesive. Used in small
proportions to increase the effectiveness of an accelerator.
Power of an adhesive layer to hold the parts of an assembly together. The two
surfaces are held together by interfacial forces which may consist of valence
forces or interlocking action. Quantitative tests are available for measuring
the adhesive strength under various environmental conditions; measured in units
such as psi. (see Bond
Material used to improve adhesion between materials. May be used in two
different modes: by pre-treatment of a substrate, and as a component in
adhesive formulation capable of enhancing adhesion durability due to the
improvement in substrate wetting and formation of chemical bonds across the
Syn. Bonding agent
Material that can be used to adhere or stick one surface to another. (see
Note: Adhesive is the general term and includes among other
cement, glue, mucilage
The layer of adhesive between the parts to be stuck together.
Separation of two bonded surfaces that occurs within the bonding material. The
adhesive separates entirely from the substrate.
Note: Adhesive failure occurs when the adhesive strength of a bonding
material is lower than it's cohesive strength.

An adhesive is in tensile loading when the acting forces are applied at right
angles to the plane of the adhesive.
The testing of bonded joints serves two purposes: first in permitting quality
control checks to be carried out during the development, production, and
processing of adhesives, and second in allowing comparative tests to be
conducted on different types of adhesive.(more

Not to be confused with absorption, adsorption is the build up of a molecule at
a surface. Adsorption generally occurs because different parts of a molecule
have an affinity for the two different phase on either side of the interface.

Adhesive that sets on contact with the air.
Exposure of materials to an environment for an interval of time. The change of
a material with time under defined environmental conditions, leading to
improvement or deterioration of properties (see
Formed by the condensation of polyhydric alcohols with polybasic acids. May be
regarded as complex polyester (thermoset).
Organic compound that contains a carbonyl group bound to nitrogen. -CON- (C
double bonded to O)
Amino resins are thermo-setting resins manufactured from amino compound and
formaldehyde. See also Urea
formaldehyde resin, Melamine
Specialty adhesive designed to cure on metals in the absence of oxygen. Often
known as locking compound or, sealant
, it is used to secure, seal and retain turned, threaded, or similarly
close-fitting parts. Based on synthetic resins known as acrylics. Primarily
used to anchor threaded joints and shafts against breaking free due to
Agent used to lessen the adhesion of the surface of products made from the
formulation to a like or different surface. Acts by producing a slight
roughening of the surface. Are typically finely divided, solid minerals, but
some are waxes.
Compounding material used to retard deterioration caused by oxidation, ozone,
light and combinations.
Note: Antidegradant is a generic term for such additives as
and UV absorbers/ light stabilizers.
Anti-flex cracking agent
Compounding material used to retard
caused by cyclic deformations.
Compounding material used to retard deterioration caused by oxidation. Usually
based on molecules that will scavenge free radicals as they are formed.
Compounding material used to retard deterioration caused by ozone.
Substance added to a material to prevent or retard the processes of oxidation
or polymerization which result in the formation of an insoluble skin on the
surface of the material.
Additive which increases the surface conductivity of adhesives and which
eliminates the accumulation of electrostatic electricity and dirt. Quaternary
ammonium salts of organic or fatty acid derivatives are typically used as
Anti-stick / Anti-tack agent
Additive incorporated in order to reduce tackiness or agglomeration of the
Asphalt / Bitumen
Dark brown to black cementitious material, solid or semisolid in consistency,
in which the predominating constituents are bitumens which occur in nature as
such or are obtained as residue in refining petroleum. The principal ingredient
in asphalt is a mastic.
