Abstract
A low cost moisture curable sealer and adhesive composition containing a polymer having reactive silyl groups and a bituminous material and having many advantages over conventional moisture cure sealer compositions, including greater elastomeric properties, improved flexibility and pliability, lower durometer, faster and deeper cure, low temperature cure. The composition is also free of carcinogens such as coal tar, toxic isocyanates, and volatile solvents.
Claims29
A moisture curable composition, comprising:
- a polymer having reactive silyl groups;
- and an asphalt material, wherein the polymer having reactive silyl groups is a polyester having silyl groups, a polyether having reactive silyl groups, or a polyurethane having reactive silyl groups.
A moisture curable adhesive composition, comprising:
- a polyurethane having reactive silyl groups;
- and an asphalt material.
A moisture curable composition, comprising:
- a polymer having reactive silyl groups;
- and
- an asphalt material, wherein the polymer having reactive silyl groups is an α, ω-telechelic silyl-terminated polymer.
A moisture curable composition, comprising:
- a polymer having reactive silyl groups;
- and
- an asphalt material, wherein the polymer having reactive silyl groups is a silyl-terminated oxyalkylene polymer.
A moisture curable composition, comprising;
- a polymer having reactive silyl groups;
- an asphalt material;
- and
- a compatibilizing plasticizer in an amount effective to wet and help disperse the asphalt material in the polymer having reactive silyl groups.
A moisture curable composition consisting essentially of:
- a polymer selected from the group consisting of polyesters having reactive silyl groups, polyethers having reactive silyl groups, and polyurethanes having reactive silyl groups;
- an asphalt material;
- a compatibilizer in an amount effective to wet and help disperse the asphalt material in the polymer having reactive silyl groups;
- optionally, a catalyst for promoting fast reaction among the reactive silyl groups of the polymer having reactive silyl groups;
- and
- optionally, one or more additives selected from the group consisting of dehydrating agents, tactifiers, physical property modifiers, storage stability improving agents, antioxidants, adhesion promoters, ultraviolet light absorbers, metal deactivators, antiozonants, light stabilizers, amine type radial chain inhibitors, phosphorous-containing peroxide decomposers, lubricants, pigments, foaming agents, flame retardants and antistatic agents.
A solvent-free, moisture curable composition for waterproofing automotive body components or for automotive underbody coating, comprising:
- “a polymer selected from the group consisting of polyesters having reactive silyl groups, polyethers having reactive silyl groups and polyurethanes having reactive silyl groups;
- and
- an asphalt material”.
