Vertellus medical glue

VERTELLUS Biothane® product range Sealants for the medical industry

Product introduction
Vertellus has more than 40 years of experience in medical industry applications and is an international manufacturer of specialty chemical raw materials. The R&D and production of Biothane® series products are completed in the United States, with customers all over the world.
The Biothane® range is a two-component polyurethane liquid casting sealant based on ricinoleate, supplied as two separate components - Vorite® polyurethane prepolymer component and Polycin® polyol component. Can be used in sealants, adhesives and coatings. In particular, it can be used for the sealing of cartridge filters such as hemodialyzers, and medical equipment.

Vorite® Series Polyurethane Prepolymers

Synthesizing prepolymer from isocyanate through pre-reaction has the following process advantages:
Moisture resistance; Freeze resistance; Programmable viscosity; Reduced exotherm, safe reaction; Controlled curing.
In terms of product performance, it can increase its versatility, reduce internal stress and reduce shrinkage.

Product Series	NCO%	Viscosity (cP)	Storage temperature (°C)	characteristic
Vorite® 689	17	11,000	> 15	high viscosity
Vorite® 1745	23.5	500	> 0	low temperature
Vorite® 2021	20	2900	> 15	low tint
Vorite® 2030	22	1200	> 20	low tint
Vorite® 2040	24.5	500	> -5	low temperature, low viscosity
