ButterGel™

All ButterGel inks are suitable for plastic and metal refills. Jumbo refills require grease follower. All inks rubber elastic in order to prevent gooping.

These inks require Special tips available from Premec SA or ESSEM Co. designated OBGL Tips (High) or Low Viscosity ink tips. Silicone grease follower in regular refill is not essential but it will provide extra protection from back leakage. There are many suppliers of Silicone Grease (Polybutene base Grease) Follower like Kwangsuk Oil & Chemical Co. Ltd in Korea. Ideal viscosity of the Silicone Follower must be 4,305 to 4,325 CPS at 25ºC. Our ButterGel inks generally have a shelf life of minimum two years in refills made of suitable materials. Provided that the refills are not exposed to extremely unfavorable climate conditions.

These inks are distinguished by especially well balanced properties. This assortment satisfies nearly all customer's requests due to a high degree of reliability and experience.
