What is epoxy acrylate?
Epoxy acrylate resins are (semi-)polymeric substances called oligomers with variable chain lengths as a result of a polymerization reaction. The resins excel in durability, hardness, flexibility and show good abrasion and chemical resistance.
What is oligomer resin?
An oligomer can be described as a molecular complex comprised of a few monomer units. As the molecular weight increases in a solution polymer within a monomer type, viscosity increases, solubility decreases and in general compatibility with other resins decrease.
How do I make epoxy acrylate?
the preparation method of an epoxy acrylate, the steps include: epoxy resin to add reactor, add 0.12～0.15% stopper and 0.3～0.4% catalyzer simultaneously, after stirring, by constant pressure funnel, drip vinylformic acid, time for adding is 1～1.5h, keep temperature of reaction 125-135 ℃, react 2～2.5h, to reacting when …
What is polyester acrylate?
Polyester acrylates are part of the acrylate crosslinkers technologies consisting of polyester acrylates, epoxy acrylates, urethane acrylates, acrylated acrylics, amine modified polyether acrylates and acrylate monomers.
Is oligomer a monomer?
In other words, oligomer is a molecule that consists of a few monomer units. Dimers, trimers, and tetramers are, for example, oligomers respectively composed of two, three, and four monomers.
What is the difference between oligomer and polymer?
The key difference between oligomer and polymer is that the oligomer forms when few monomers undergo polymerization whereas the polymer forms when a large number of monomers undergo polymerization. Polymers are large macromolecules that contain a large number of repeating units; we call them monomers.
What is urethane acrylate?
Urethane acrylate oligomer technology is based on isocyanate terminated urethane prepolymers. The term oligomer is synonymous with the term prepolymer commonly used in the urethane industry. Basically, urethane acrylate oligomers are simply formed by another synthesis step beyond urethane prepolymers.
What is aliphatic urethane acrylate?
The aliphatic urethane acrylate EBECRYL® 225 is a 10-functional hardcoat product for various plastic substrates use and can be used as a binder to improve the hardness and scratch resistance of a coating.
Is an oligomer a polymer?
Oligomers are low molecular weight polymers comprising a small number of repeat units whose physical properties are significantly dependent on the length of the chain.
How many monomers are in a oligomer?
