Modulus of elasticity or E-modulus is a measure of the elasticity of a material. It is a material-dependent constant that indicates the relationship between the relative change in length of the material and the applied stress, below the elasticity limit. The modulus of elasticity indicates the slope of the first part of the stress-strain diagram.
ECB | What is ECB?
ECB is a type of plastic sheeting used as a plastic roofing membrane. Plastic roofing membranes (ECB, EVA and PVC) are used as an alternative to bituminous roofing materials.
Eco resin | What is eco resin?
The ECO resin we developed is based on surester combined with polymers. This gives you a completely solvent-free resin with which you can both cast and laminate. for more info; https://v-sure.eu/products/polyester/
Elastic | What is elastic?
Elastic means deformable or stretchable. A perfectly elastic material springs back immediately once the mechanical load is removed, with the work done to cause the deformation being returned in full.
Elastic deformation | What is elastic deformation?
In the case of elastic deformation, the material returns to its original shape completely once the stress is removed. Elastomers are usually composed of very long linear macromolecules, with their high elasticity being achieved through (a limited number of) cross-links between the different chains. This forms a network whose plasticity decreases as the number of cross-links increases. In the case of natural rubber, we refer to a vulcanisation process, as cross-linking occurs through heating with sulphur. Elastomers are highly elastic and have a high coefficient of friction. Examples of elastomers include: all synthetic rubbers, isoprene rubber, butadiene rubber, styrene-butadiene rubber (SBR), polyurethane rubbers and silicone elastomers.
Elastic elongation | What is elastic elongation?
Elastic elongation is the extension of the material, expressed as a percentage of its original length, within the elastic range. Once the tensile force is removed, the material will return to its original length.
Elastic limit | What is elastic limit?
The elastic limit is the highest stress at which elastic deformation still occurs. The elastic limit is, therefore, the boundary of elasticity.
Elasticity | What is elasticity?
Elasticity is the ability of a material to spring back to its original shape after undergoing deformation. A perfectly elastic material springs back immediately upon removal of the mechanical load, with the work done to cause the deformation being returned in full. When deformation and recovery occur with a slight delay, the restoration of shape and the removal of the load may be complete, but some work is nevertheless lost as heat.
Electrostatic charge | What is electrostatic charge?
Electrostatic charging occurs when there is friction or even simple contact between two insulators. The electrical charges formed can be annoying and even dangerous under extreme conditions due to their force effects.
Elongation at break | What is elongation at break?
Elongation or elongation at break indicates a mechanical property. The elongation indicates the relative elongation at which the material actually breaks through. When a material has a high elongation, it is called tough. Materials with low elongation are called brittle.
Enameling | What is enameling?
Enameling is applying a thin, glassy, opaque or transparent mass to cover or decorate metal, glass, stone objects or ceramics.
Endurance curing | What is endurance curing?
End cure is the final stage of the curing process of resins
EP resin - epoxy resin | What is epoxy resin?
The resin component is prepared by condensation and addition of epichlorohydrin and a divalent or multivalent phenol derivative. The reaction between these two raw materials produces the epoxy resin. The epoxy group found twice in each molecule of the resin is highly reactive and can react with appropriate substances called hardeners. Polyamines and polyamides are most commonly used as hardeners. These substances are able to open the ring at the epoxy group by possessing reactive hydrogen atoms. The curing process is an exothermic reaction, so heat is released. for more info, see: https://v-sure.eu/products/epoxy/
Epichlorohydrin | What is epichlorohydrin?
Epichlorohydrin is also known as carbon dioxide chloride. Through a condensation reaction and an addition reaction of epichlorohydrin and a divalent or multivalent phenol derivative, epoxy resin is obtained.
Epovoss | What is epovoss?
Epovoss is a brand offered by Vosschemie. Epovoss products are always epoxy resin-based and can serve, for example, as varnishes, adhesives, fillers or laminating resins. Epovoss has always been at the forefront of manufacturing epoxy resin products for applications on boats. Epovoss products also come into their own in the construction industry. for leather info, see; https://v-sure.eu/products/epoxy/epoxy-resin/
Epoxy | What is epoxy?
Epoxy or polyepoxide is a chemical compound. It is an epoxide polymer composed of 2 carbon atoms (C) and 1 oxygen atom (O) in a ring-shaped structure. Epoxy distinguishes itself from polyester by, for example, greater flexibility, the fact that it adheres to almost any surface and the fact that it yellows under the influence of UV and therefore has to be finished with UV-resistant lacquer. for more information, see https://v-sure.eu/products/epoxy/
Epoxy adhesive | What is epoxy adhesive?
Epoxy adhesive is a two-component adhesive that has both industrial and domestic applications. One component, specifically the filler, is an epoxy resin. The second component is a hardener, which when mixed creates a strong adhesive bond. Epoxy adhesive can be applied as a topcoat (coating), but is also used in combination with glass fibres. The adhesive can be easily removed by carefully and not excessively heating the joint with a paint burner. For more info; https://v-sure.eu/epoxy-adhesive-quick-drying-water-resistant
Epoxy EP | What is epoxy EP?
Epoxy or polyepoxide is a chemical compound. It is an epoxide polymer composed of 2 carbon atoms (C) and 1 oxygen atom (O) in a ring-shaped structure. Epoxy distinguishes itself from polyester by, for example, greater flexibility, the fact that it adheres to almost any surface and the fact that it yellows under the influence of UV and must therefore be finished with UV-resistant lacquer.

Epoxy laminate | What is epoxy laminate?
Epoxy laminate is an epoxy-based laminate. Epoxy BK, for example, is a thin liquid laminating epoxy used to produce moulded parts in combination with fibreglass, carbon fabric or aramid fabric.
Epoxy mortar | What is epoxy mortar?
Epoxy mortar can be used to fill cracks and holes in concrete, in places where quick-setting cement might come loose. Epoxy-based mortars are highly resistant to diluted acids and alkalis. Epoxy mortar can even be used to reinforce surfaces, for example at the edge of a stair tread or as a base for machinery.
Epoxy putty | What is epoxy putty?
Epoxy filler is a filler made from epoxy. For example, cracks and holes in a boat can first be filled with epoxy filler before the boat is further coated. For more information, see: https://v-sure.eu/products/filler-putty/epoxy-filler/
Epoxy resin | What is epoxy resin?
Epoxy resins have many successful applications in the plastics industry. This is mainly due to the fact that they are versatile, easy to use and therefore universally applicable. Epoxy resins have many appearances: adhesive, paint, powder, resin, laminate, composite, etc. Cured epoxy resins are super-strong materials that hardly shrink at all. They insulate very well and can be used at operating temperatures from -80 to +180 °C. They are chemically very stable and exceptionally resistant to fractures and cracks. Liquid epoxy resins are known for their exceptional adhesion to all possible surfaces. They are always completely bubble-free without the need for external pressure. Pressed or cast pieces, as well as composites, weigh much less than the traditional materials that have been replaced in cars and aircraft. This significantly reduces fuel consumption, benefiting the environment. Epoxy resins thus have many applications, they are used for example in household appliances, in large building structures, in computers, in satellites, on beverage cans, on ship walls, etc. For more info; https://v-sure.eu/products/epoxy/
EVA | What is EVA?
EVA stands for ethyl vinyl acetate. It is a random copolymer. A copolymer is formed when at least two different monomer units are combined in the polymer chain. In a random copolymer, the different monomer units are arranged in a random order within the polymer chain. EVA is a type of plastic film used as a plastic roofing membrane. Plastic roofing membranes (ECB, EVA and PVC) are used as an alternative to bituminous roofing membranes.
