Master Bond EP30-4 is a transparent, low viscosity fast curing adhesive, sealant and coating. It is especially recommended for applications requiring rapid cure without adding external heat. When EP30-4 is spread in films thin as 0.025in, it will become tack free in as little as 30 minutes. This makes it ideal for use as a conformal coating where heating the components or substrate is not possible.
Another property is the excellent optical clarity of the system. Offering superb spectral transmission in thin sections and superior non-yellowing properties it is ideally suited for use in fibre optic bonding applications.
The two component EP30-4 epoxy produces high strength, rigid bonds with tensile strength greater than 10,500 psi and bond shear strength, exceeding 2000 psi. It has a working life of 8-10 minutes and can easily be applied by spraying or flow coating.
