This cationic photoinitiator is particularly recommended for use at doses less than 1%, combined with a photosensitiser, e.g. of isopropyl thioxanthone type, for the formulation of inks, pigmented coatings or varnishes applied in thicknesses of greater than 10 microns. It can also be used for the formulation of photopolymers intended for use in applications such as electronics (photoresists, etc.) the graphic arts (printing plates, etc.) composite materials, fibre optics coatings, etc.

BLUESIL PI 2074 may be stored at temperatures between -20°C / -4°F and 50°C / 122°F for up to 48 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


BLUESIL​ PI 2074 is a cationic photoinitiator for use with epoxy resins, vinyl ethers or any other type of oligomer which polymerises cationically. It is also suited to the formulation of hybrid radical / cationic systems.
