An applicator system includes a delivery apparatus and a dispenser assembly. The delivery apparatus includes a carrier configured to support first and second containers containing first and second liquids, the first and second containers having first and second outlets. The dispenser assembly includes a frame, a first distribution manifold removably connected to the frame, and a plurality of nozzles. The first distribution manifold includes an inlet and a plurality of outlets in fluid communication with the inlet. Each of the plurality of nozzles is removably fluidly coupled to a corresponding outlet of the first distribution manifold. The applicator system further includes a first hose, wherein one end of the first hose is removably fluidly coupleable to the inlet of the first distribution manifold and another end of the first hose is removably fluidly coupleable to at least one of the first outlet and the second outlet.

A one-part, low viscosity, moisture curable composition which exhibits excellent shelf stability in the absence of water, but which quickly cures at ambient conditions upon exposure to moisture in the air is a substantially anhydrous mixture containing an acetoacetate functional compound and a polyisocyanate functional compound. The composition can be suitably formulated for use as an ambient temperature, moisture curable adhesive, sealant or coating composition. The acetoacetate functional compounds have a relatively low viscosity as compared with conventional isocyanate functional compounds and thereby reduce or eliminate the need for plasticizers, organic solvents, or both. The cure chemistry of the composition simultaneously consumes and generates moisture at approximately the same rate thereby facilitating rapid cure under even low humidity conditions, and allows for efficient and facile curing of even thick layers of the composition.

One-part, low viscosity, moisture curable composition

An organoclay in which a quaternary long chain fatty amine is ionically bonded to clay platelets is found to function both as a filler or thickener as well as a compatibilizer in an asphaltic polyurethane (PUR) dispersion. When a PUR prepolymer is mixed into a homogenized blend of asphalt and organoclay under high shear, a phase inversion occurs the result of which is that a microdispersion of asphalt particles (preferably 1 .mu.m-44 .mu.m) becomes the dispersed phase which is uniformly scattered throughout the PUR prepolymer (the continuous phase). This dispersion is found to be an excellent adhesive, particularly for roofing components which can be secured without using conventional fasteners, and it is stable and moisture-curable to afford, when cured, an elastomer having excellent adhesion to surfaces exposed outdoors. It is also user-friendly because it is solvent-free. The asphalt is treated to react all functional groups it may have because they may react with a functional group of the PUR prepolymer. The organoclay compatibilizer may be supplemented with a compatibilizer used in the parent case where the viscosity of the dispersion is to be lowered, and to save on the cost of making the dispersion. A sprayable adhesive dispersion may be formed by diluting the organoclay compatibilized dispersion with a plasticizer which, together with the asphalt and organoclay, becomes an integral part of the elastomer when the PUR is cured.

Solvent-free, organoclay-filled asphaltic polyurethane dispersion and

A moisture-curable, substantially solvent-free and anhydrous blend of a bituminous material such as asphalt and a liquid prepolymer is disclosed, which blend when cured, results in an elastomer having excellent adhesion to surfaces exposed outdoors. The stability of the blend derives from asphalt being microdispersed in a dispersed phase within a continuous phase of the liquid prepolymer so that particles of asphalt are in the size range from 0.5 .mu.m to 100 .mu.m. The asphalt is treated to react all functional groups it may have because they may react with a functional group of the liquid prepolymer. The prepolymer is a polyurethane, a terpolymer of ethylene-propylene-diene, or a silicone. The microdispersion is stably maintained by a compatibilizer having opposed substantially polar and non-polar terminal portions, present in an amount in the range from 0.01 to 5 parts per 100 parts of the blend. The compatibilizer is chosen from (A) an ester of a C.sub.2 -C.sub.12 branched or straight chain polyol; (C) a mono- or diester of a polyether polyol; (D) an ester of a polyester polyol and a C.sub.9 -C.sub.24 fatty acid; (E) an ester of a polyether diol such as a polyalka(C.sub.5 -C.sub.6)diene diol and, a polydimethylsiloxane diol; or, (F) an ester of a polyester polyol having a repeating unit derived from acrylic acid and a polyol selected from the group consisting of a C.sub.2 -C.sub.12 alkylene diol, or triol; a polyalkylene C.sub.2 -C.sub.4 diol; and a polyoxyalkylene C.sub.2 -C.sub.4 diol.

An apparatus (10) for applying fluid roof panel adhesive to a substrate includes a holding tank (12) for holding a supply of adhesive vertically above the substrate. The tank is supported by a pair of spaced wheels (14) and has a handle (16) to enable moving the device over the substrate. Openings (32) in a lower wall (30) of the tank enable adhesive to flow onto the substrate. Blocking members (36) associated with each opening are movable in response to the position of a lever (20) to enable or prevent flow of adhesive through the openings. Movement of the apparatus over the substrate provides for controlled deposition of uniformly spaced beads of adhesive suitable for holding roof panels to the substrate.

Adhesive application apparatus

The present invention relates to low slope roofing systems, particularly in commercial (as opposed to residential) roofing applications. More specifically, the fastener-free roofing system of the present invention is directed to the use of a curing adhesive composition which will simply and safely secure roofing insulation to a roofing deck without the need for mechanical fasteners.

Fastener-free roofing system and method

The present invention relates to a compatibalizing agent useful in compatibalizing a substantially non-polar compound, such as asphalt, with a substantially polar organic compound, such as an isocyanate prepolymer. The compatibalizing agent consisting of a polymer unit, or of two such units being either identical or different linked together by an ester, carbon or ether bond, said unit having the following formula:

Substantially solvent free asphaltic and method relating thereto

A protective cap for fastener heads includes a preformed member formed of a naturally tacky compound of unvulcanized butyl rubber, a reinforcing layer of a non-woven polyester fabric, and a silicone-coated polyethylene release liner. The preformed member has a dome-shaped central portion and a surrounding generally flat annular flange. The reinforcing layer of the polyester fabric is disposed over a top surface of the preformed member to form a homogeneous cap construction, and the release liner covers the tacky bottom surface of the preformed member to prevent the cap from adhering to surfaces until ready for use. A plurality of the protective caps are formed in a manipulatable sheet unit and are maintained thereon by the natural tackiness of the unvulcanized butyl rubber compound. The caps are removed individually from the sheet unit, the liner is removed, and the cap is placed over an exposed fastener head so that the tacky bottom surface of the flange surrounding the fastener head adheres the cap to a surrounding surface and the tacky interior surface of the dome-shaped central portion adheres to the bolt head with the central portion being moldable about and encasing the fastener head.
