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.
Claims27
A mineral clay composition comprising:
- a mineral clay mixture which has been treated with an alkyl quaternary ammonium salt, the mineral clay mixture comprising a mixture of palygorskite, sepiolite and a smectite, wherein the combined amount of palygorskite and sepiolite in the mineral clay mixture comprises between about 50% to about 95% by weight of the mineral clay mixture.
A mineral clay composition comprising:
- a mineral clay mixture which has been treated with an alkyl quaternary ammonium salt, the mineral clay mixture comprising sepiolite and a smectite, wherein the amount of sepiolite in the mineral clay mixture comprises between about 50% to about 95% by weight of the mineral clay mixture.
A mineral clay comprising:
- a mineral clay mixture which has been treated with an alkyl quaternary ammonium salt, the mineral clay mixture comprising palygorskite and a smectite, wherein the amount of palygorskite in the mineral clay mixture comprises between about 50% to about 95% by weight of the mineral clay mixture.
