  • Organoclay compositions for gelling unsaturated polyester resin systems
    Patent number: 6635108
    Abstract: An organoclay composition for gelling unsaturated polyester resin/monomer systems comprising a mineral clay mixture which has been treated with an alkyl quaternary ammonium compound. The mineral clay mixture comprises two components: mineral clay (a) comprising greater than 50 wt. %, based on the weight of the mineral clay mixture, of a mineral clay selected from the group consisting of sepiolite, palygorskite and mixtures of sepiolite and palygorskite; and mineral clay (b) comprising less than 50 wt. %, based on the weight of the mineral clay mixture, of a smectite.

  • Organoclay compositions and method of preparation
    Patent number: 6036765
    Abstract: An organoclay composition comprising a mineral clay mixture which has been treated with an alkyl quaternary ammonium salt said mixture comprising: mineral clay (a) comprising 50 to 95 wt. %, based on the weight of the mineral clay mixture, of a mineral clay selected from the group consisting of sepiolite, palygorskite and mixtures of sepiolite and palygorskite; and mineral clay (b) comprising the balance by weight of the mineral clay mixture, of a smectite.

  • Method for preparing high solids bentonite slurries
    Patent number: 5266538
    Abstract: A smectite clay is provided as an elevated solids aqueous slurry e.g. up to 50% solids, which is composed of the smectite clay slurried or dispersed in water containing an effective concentration of a monovalent salt. When such a salt is present in the clay slurry, the clay does not swell appreciably, is essentially inactive, and the slurry can be shipped and stored without creating a gelling problem. When this slurry is diluted with fresh water at the point of application to make it of the desired solids content for use, the smectite clay is activated and exhibits the desired properties, such as viscosity, retention, etc.

  • Process for producing bentonite clays exhibiting enhanced solution viscosity properties
    Patent number: 5248641
    Abstract: A process for upgrading a crude bentonite ore such that it can be used advantageously to prepare unusually high aqueous solution viscosities. This sequence comprises initially subjecting the crude ore to a working or shearing stage, followed by a drying step to about a 5% moisture level. Na.sub.2 CO.sub.3 is then dry-blended with the material, and the sequence is completed by subjecting the mix to a pulverizing step.
