KimaCell®HPMC K200M FG is a natural cellulose, which is a water-soluble cellulose derivative obtained through alkalization treatment, etherification modification, neutralization reaction, washing and drying, etc. Its source is abundant and renewable, environmentally friendly and biodegradable. As a water-soluble polymer material, HPMC has good water-soluble, dispersing, thickening, water-retaining and film-forming properties. The coating film formed is colorless, odorless, tough and transparent, and is widely used as drug coating and sustained-release preparations rate-controlling polymer material.
HPMC has good water-soluble, dispersing, thickening, water-retaining and film-forming properties, and can be used for the seed coating.

KimaCell® HPMC K200M FG is applied to seed coating, and the optimal addition ratio is obtained through experiments of different addition amounts of hydroxypropyl methyl cellulose, and a germination test is carried out to verify its effect on seed germination, aiming to provide a reference for the application of HPMC in the field of agricultural seed coating.
The film-forming agent for seed coating is a substance that can adhere active components such as pesticides, micro-fertilizers, growth regulators and slow-release agents in the seed coating agent to the surface of the seed and solidify to form a film. When the seed coating agent is in the preparation state, the film-forming agent dissolves into a colloid in water, providing a supporting framework for the suspension of other components in the preparation, and ensuring that the seed coating agent product has a certain viscosity; when the seed coating agent dries on the surface of the seed and forms The film agent is polymerized into a continuous film with a certain strength, which binds the pesticide components and prevents them from falling off, and has a slow release effect on the active components in the coating film. The current seed coating agents in my country still have the phenomenon that the coating is easy to fall off, and the coating layer is often delaminated, precipitated and not firm. The shedding of the coating layer will reduce the content of active ingredients in the coating, thus affecting the promotion and application of seed coating technology.
