Abstract
Plastisols based upon plasticizable polyvinyl chloride, or co-polymers of vinyl chloride, and plasticizers, as well as a content of polymerizable esters of .alpha.,.beta.-unsaturated carboxylic acids and polyhydroxy alcohols, and solid inorganic percompounds, which can be used for the production of firmly adhering coatings and adhesives.
Claims7
A PVC plastisol comprising
- A. from 10 to 50% by weight of a plasticizable polymer selected from the group consisting of polyvinyl chloride and copolymers of vinyl chloride with up to 20% by weight of ethylenically unsaturated monomers copolymerizable with vinyl chloride,
- B. from 6 to 60% by weight of a plasticizers for polyvinyl chloride, wherein the ratio of component A to component B is from 1:0.6 to 1:2,
- C. from 1 to 20% by weight of an ester of an .alpha.,.beta.-unsaturated carboxylic acid having from 3 to 8 carbon atoms and at least one carboxyl group with an aliphatic polyhydroxy alcohol, with the proviso that at least two olefinic bonds are present in said ester,
- D. from 0.1 to 6% by weight of a solid inorganic percompound selected from the group consisting of an alkaline earth metal peroxide, an alkali metal peroxycarbonate, an alkali metal perborate, an alkali metal permanganate, alkali metal perchlorate, alkali metal persulfate and the mixtures thereof, and
- E. from 0 to 70% by weight of inert material selected from the group consisting of inorganic fillers and mineral pigments.
