Microsil 200 – Microsil 200S

Very low density and resistant microspheres

MICROSIL products are made of inert microspheres obtained by thermal treatment at high temperatures that creates a hard glass crust around a hollow space filled by air. This spherical and multi-cellular structure allows to generate polyfunctional fillers with a very low density.

MICROSIL 200 and its coated version MICROSIL 200S, have been designed to be used in applications where a small particle size is not needed. MICROSIL 200S is a more suitable product in applications where it is required a lower viscosity or a smaller absorption.

Properties

  • Allows an important reduction of the system density.
  • MICROSIL improved the yield in the application of the final product.
  • Improves flow and leveling of coatings and mortars.
  • Reduces shrinking and crack formation.
  • MICROSIL allows reducing binder demand increasing filler concentration. This will decrease cost by volume unit in final product.
  • Reduces heat transmission.
  • It is fire resistant.
  • White colored.
  • Good compressive resistance.
  • High chemical inertia and neutral pH.

Fields of application

  • Joint fillers for drywall and gypsum boards.
  • Cement boards.
  • Synthetic marble and polymeric mortars.
  • Mortars and stuccos.
  • Bitumen membranes for waterproofing.
  • Asphalt emulsions.
  • Resin based waterproofing coatings.
  • Refractory materials.
  • Putties and mastics.
