  • Solvent based tiecoating for use with mastic coating
    Patent number: 5112655
    Abstract: A method for improving the quality of a mastic coating system by using a solvent-borne tiecoat, and a solvent-borne tiecoat composition are provided. The tiecoat is applied to a substrate in order to correct substrate deficiencies which would cause premature failure of a mastic coating applied directly to the substrate. The mastic coating is then applied to the tiecoat to yield a superior mastic coating composition.

  • Latex-modified asphalt emulsion tiecoat mastic coating system
    Patent number: 5085896
    Abstract: A method for improving the quality of mastic coating system by using a tiecoat which is composed of an aqueous latex-modified asphalt emulsion. The tiecoat is applied to a substrate and then at least one subsequent coating is applied to the tiecoat to yield a mastic coating system having superior resistance to lack and bleed-through discoloration.

  • Quick-cure, flexible polymer composition
    Patent number: 4571420
    Abstract: Compositions which remain flexible when cured comprising low T.sub.g polymers containing pendant unsaturation, polyfunctional mercaptan, and vanadium compound, are disclosed. The compositions, which cure upon exposure to air and become tack-free rapidly, are especially suitable for roof mastics, coatings, and caulks.

  • Inhibitors for vinylbenzyl chloride and vinyltoluene decomposition
    Patent number: 4087335
    Abstract: A method is disclosed for stabilizing vinylbenzyl chloride and vinyltoluene against violent decomposition in the presence of iron and chlorine at ambient and above ambient temperatures which comprises contacting the vinylbenzyl chloride or vinyltoluene with an amount of a Lewis base sufficient to inhibit the decomposition during the preparation, purification or storage of said vinylbenzyl chloride or vinyltoluene.
