Application Areas

SpeedCure BCIM is often used with leuco dyes for direct write laser imaging or with H-donor coinitiators such as thiols to initiate acrylate systems.

SpeedCure VLT is used in visible light curing, thick coatings, high resolution microelectronics, polyimide formulations and LED 3D printing.

SpeedCure 8001 is a mid-wavelength absorbance type I photoinitiator used in the electronics sector for colour resists, imaging, production of screens and polyimide potting.

SpeedCure 8002 is a long wavelength absorbance type I photoinitiator used in the electronics sector for colour resists, imaging, production of screens and polyimide potting.

SpeedCure PDO is a very efficient short wavelength absorbance type I photoinitiator. It is used almost exclusively in imaging applications in electronics.

SpeedCure EAQ abstracts hydrogens from the resin backbone of esters and urethanes and does not require an amine synergist. It is widely used in electronics for acid resists where amines cannot be tolerated. It can also be used as a sensitiser for other photoinitiators.

Application Areas

UviCure S105 is a difunctional cycloaliphatic epoxide resin which gives clear, hard, glossy coatings.

Cycloaliphatic epoxides

UviCure S128 is an adipate based difunctional cycloaliphatic epoxide resin which can be used alone or as an additive in S105 based formulations to increase the flexibility of a cured coating.

UviCure S130 is an alcohol functional mono oxetane. It is used as a reactive diluent in cationic formulations and will increase curing speed and adhesion.

Oxetanes

UviCure S140 is a low viscosity monofunctional oxetane suitable for cationic formulations. It will reduce the viscosity of resin formulations and give added flexibility to a cured coating.

UviCure S150 is a difunctional aromatic oxetane which can be used as an additive in cationic formulations to increase hardness, chemical resistance and thermal resistance.

UviCure S160 is an aromatic difunctional oxetane which can be used in cationic formulations to give cured films with high chemical resistance, mechanical strength and minimised shrinkage. UviCure S170 is a low viscosity oxetane-methacrylate hybrid resin which can be used in epoxide/acrylate hybrid curing systems which can give superior properties to either system used alone.
