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.
Claims21
An organoclay composition for gelling unsaturated polyester resin Systems comprising a mineral clay mixture which has been treated with an alkyl quaternary ammonium salt, said mixture comprising:
- 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.
An unsaturated polyester resin composition comprising a solution of an unsaturated polyester resin in a monomer which is capable of undergoing a crosslinking reaction with the resin and including a
- mineral clay mixture which has been treated with an alkyl quaternary ammonium compound, said mixture comprising:
- 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.
