Carbon Footprint
A measure of the impact our greenhouse gas emissions have on the environment, and in particular on climate change. It can be calculated for a particular product, for a manufacturing site or for any activity we undertake. It is a measurement of all the greenhouse gases produced in units of tonnes (or kg) of carbon dioxide equivalent. AkzoNobel has a clear Carbon Policy setting out targets and ambitions to be achieved by 2015 and 2020
Carbon neutral
A commonly accepted terminology for something having net zero emissions of greenhouse gases (for example, an organisation or product). As the organisation or product will typically have caused some greenhouse gas emissions, it is usually necessary to use carbon offsets to achieve neutrality. Carbon offsets are emissions reductions that have been made elsewhere and which are then sold to the entity that seeks to reduce its impact. In order to become carbon neutral it is important to have a very accurate calculation of the amount of greenhouse gas emissions which need to be offset – requiring calculation of a carbon footprint
Catalyst
Hardener, activator, accelerator, curing agent ; a material which starts a reaction but is not actually consumed in that reaction
Cat-eye
Hole shaped like a cat's eye ; cratering
Cathodic Protection
Corrosion prevention by sacrificial anodes, usually a zinc alloy
CFC or Chlorofluorocarbons
These are materials which traditionally had many applications, such as use as propellants in aerosols and as coolants in refrigeration units. Known to deplete the ozone layer in the Earth’s stratosphere , most uses have been severely restricted or banned under international treaties e.g. Montreal protocol
Chalking
Powdering of surface
Checking
Slight V-shaped breaks appear in a paint film due to uneven shrinkage through the cross section of a coat of paint
Chipping
1. Cleaning steel using special hammers 2. Type of paint failure
Chlorinated Rubber
A particular film former used as a binder made by chlorinating natural rubber
Cissing
Fish eyes ; small causer-like depressions in a paint film
Cleaner
Solvent for cleaning paint equipment
Coat Tar Epoxy Paint
Paint made of a combination of coal tar with epoxy resin
Coat Tar Urethane Paint
Paint made of a combination of coal tar with urethane resin
Cobwebbing
Premature drying causing a spider web effect when spraying, (paint dries before it hits the substrate)
Color Retention
Ability to retain original color
Compatibility
Ability to mix with or adhere properly to other components
Copper-free
Copper is used in antifouling paint as a biocide. Copper-free paint does not contain any copper (either as a pigment or as part of the polymer)
Corrosion
Decay ; oxidation, deterioration due to interaction with environments
Coverage Rate
Non technical number that tells you how much area you can paint with a given volume of material
Cracking
Splitting ; disintergration of paint by breaks through film
Cratering
Formation of holes or deep impressions in paint film
Crawling
Shrinking of paint to form uneven surface
Crazing
A pattern of tiny cracks in the surface of a gelcoat
Cross-linking
A particular method by which chemicals unite to form films
Curing
Hardening
Curing Agent
Catalyst, hardener, activator, accelerator, reactor ; a material that reacts with another to convert a liquid coating to a solid coating.
Curtaining
Sagging ; excessive flow of paint on vertical surfaces causing imperfections with thick lower edges in the paint film, not as excessive as runs
