Products will include high performance cellulosics (methylcellulose, hydroxypropyl methylcellulose, hydroxyethyl methylcellulose, carboxymethyl cellulose, ethylcellulose
, hydroxyethyl cellulose, and nitrocellulose) as well as companion chemistries (polyethylene oxide, redispersible latex powders, and cationic polymers).
, tertiary butylhydroquinone and starch aluminium octenyle succinate.
The company's range of products is comprised of, but not limited to, epoxies, polyurethanes, polyesters, alkyds, nitrocellulose, UV chemistries, ethylcellulose
, vinyls, acrylics, acid resists, gaming/security and special effects inks.
Enteric coatings generally consist of various polymers, such as cellulose acetate phthalate, cellulose acetate butyrate, ethylcellulose
, polyvinyl acetate phthalate, and methacrylate copolymers.
When the tablet is chewed, cracks form around the ethylcellulose
polymers, then gastric juices inside the body combine with the polyethylene oxide to form the glue-like substance to seal the cracks.
