Passive materials are materials that form a natural protective layer (passivation layer) on their surface, protecting them from chemical or electrochemical degradation.
Peel strength
Peel strength refers to the load value required to separate bonded mating parts in a peeling motion.
physikalisch abbindend
Physikalisch abbindende Klebstoffe erhalten ihre Festigkeit durch das Entweichen der Löse- oder Dispergiermittel oder durch Abkühlung nach vorausgegangener Erhitzung.
plastically deformable
Plastically deformable means that a material can permanently change shape under stress or deformation without breaking or cracking.
Plasticizer
In adhesive bonding technology, the interaction of plasticisers in the plastic with the adhesive and vice versa must be taken into account in order to prevent brittleness or failure.
polycondensation
Polycondensation refers to a type of reaction where two molecules react to form a larger molecule and a smaller molecule such as water, ect. is released.
polyurethane adhesives
Polyurethane adhesives are adhesives based on polyurethane and have high tensile strength and shear strength.
post-crosslinking
Post-crosslinking is a process in which polymer structures that are already crosslinked are linked together by further chemical reactions.
Prepolymer
A prepolymer is a chemical compound that consists of a polyol and an isocyanate component and is not yet fully cross-linked.
Primary packaging
The primary packaging is the packaging that is in direct contact with the product. According to the CLP Regulation, the contents must be labelled on the primary packaging.
processing temperature
Processing temperature refers to the ideal temperature at which an adhesive should be processed to achieve the quality of the cured adhesive.
processing time
Processing time refers to the amount of time a two-component adhesive or other two-component material can be worked after mixing before it becomes too hard.
