Welcome to Imerys Performance Minerals

Seed Coatings

Seed Coatings Imerys minerals improve seed homogeneity, integrity and seeding production

Seeds are coated for ease of handling, singulation, precision placement and the incorporation of beneficial chemicals or microbials. Coated seeds are accepted widely as a standard product for many crops.

Imerys minerals are used in seed encrusting and pelleting

  • Color
  • Lubrication
  • Increase seed size / weight
  • Addition of pesticides / inoculants
  • Improve seed placement and germination rate = “Stand establishment”
  • Vegetables, “forage”, cotton, tobacco, sugar beet
  • Minerals used as pigments, pigment extender, resin extender

Imerys minerals are used in film coating or seed enhancement

  • Color - all genetically modified seeds need to be colored for identification
  • Lubrication
  • Addition of pesticides / inoculants
  • Minerals used as pigments, pigment extender, resin extender

Calcium Carbonate for seed coatings

  • Low cost seed builder, increasing seed dimensions, easier to handle
  • Achieves better seed to soil contact
  • Less puddling of seed
  • Penetrates stubble and thatch

 

Recommended Grades

  • MicroWhite 100 
  • CP Filler

Diatomaceous Earth for seed coatings

  • Biogenic amorphous silica, disks or drums; dependent on diatom species
  • Rigid but porous structure
  • Lower bulk density / high porosity than limestone
  • Lower mass for same coating thickness
  • Effective carrier or diluent ‘pre-mix’ for active ingredients
  • Increases oxygen and water transport to seed after planting

 

Recommended Grades

  • Diafil 630

  • Celite 209

Expanded milled perlite for seed coatings

  • Friable but porous structure
  • Lower bulk density / high porosity than limestone
  • Lower mass for same coating thickness
  • Increases oxygen and water transport to seed after planting

 

Recommended grade:

  • Harborlite 635

Synthetic Calcium Silicate for seed coatings

  • Flow aid at very low addition rates
  • Liquid pesticide carrier
  • Carries hydrophobic components into hydrophilic formulation

 

Recommended grades:

  • Micro Cel E

 

Talc

  • Reduces moisture pickup during storage – prevents premature germination
  • After planting, capillary action between particles draw in and  retain water
  • Slight increase in porosity improves gas transport
  • Establishes a micro-environment for stimulating vigorous growth
  • Increases longevity of Mycorrhizae and other Biological additives
  • Improves performance of Super Hydrating Polymers (SHPs)
  • Lower pH than limestone, improves germination rate
  • Better surface finish and appearance, reduced dust-off
  • Increases seed lubricity and planter efficiency

 

Recommended grades:

  • Silverline 002
