Sealer Designed for Metal Roof Applications

Drop-Stop sealer was specifically designed for application to metal roofs and problem areas such as gutters, expansion joints, etc. Drop-Stop can easily be applied over sloped, contoured surfaces and will give long lasting, colorful protection, according to the company. Made from select synthetic rubbers, Drop-Stop is applied effortlessly as heavy bodied paints. This unique material actually stretches and recovers to bridge roof joints in which thermal movement can be expected. With 1500 PSI tensile strength and 600 percent elongation capabilities, Drop-Stop can single handedly tackle most metal repairs. White Drop-Stop is stocked in: 20 oz. sausage packs, 1 gallon pails, 5-gallon buckets and 55-gallon drums.

High-Performance Adhesive/Sealant Introduced for Rooftop Support System

Green Link Adhesive/Sealant

Green Link offers a new adhesive/sealant designed for use with the company’s KnuckleHead Rooftop Support System. Green Link Adhesive/Sealant bonds and seals the KnuckleHead Universal Base and is effective on a wide range of roof surfaces. The new adhesive/sealant has been specially formulated to adhere to PVC, EPDM, TPO, and mod bitumen, as well as the KnuckleHead base itself, which is composed of glass-reinforced nylon.

According to the company, Green Link Adhesive/Sealant is based on polyether chemistry. It cures by exposure to moisture, so it can be applied to damp surfaces and will not shrink upon curing. It will not discolor from UV exposure, can be applied at temperatures as low as 32°F, and is capable of joint movement in excess of 35 percent, states the company. It is available in standard 10.1-ounce cartridges.

“The KnuckleHead base is unique in that it can be adhered directly to the roof membrane,” said Ondrej Pekarovic, Green Link design engineer. “While there are some products on the market that effectively bond and seal the KnuckleHead base, Green Link adhesive/Sealant is the only product that effectively adheres to even the most challenging types of PVC membranes.”

Mule-Hide Products Co. has added 100 percent Silicone Sealant choices to its Silicone Roof Coating System, expanding the color offering to include clear and the packaging options to include 10-ounce tubes.
 
100 percent Silicone Sealant is a mastic version of the Mule-Hide 100 percent Silicone Roof Coating. It is a moisture-cure silicone sealant designed for use in sealing and repairing roofs, masonry, architectural sheet metal, and metal roof seams and fasteners. 
 
The addition of clear sealant allows contractors to complete projects that would otherwise require color-matching. It is available packaged in tubes only.

In addition to clear, the tubes are available filled with white sealant. The plastic cartridges are an option for use in smaller applications or when precision is required. They also can be submerged under water to repair roof leaks, gutters and downspouts.
 
100 percent Silicone Sealant provides adhesion to concrete, masonry, polyurethane foam, EPDM membranes, TPO membranes, aged PVC membranes, aged acrylic coatings, granular cap sheets, wood, metals, Kynar finishes and most other building materials. When using 100 percent Silicone Sealant with a TPO roof membrane, Mule-Hide Si TPO Primer must be applied first. 
 
The sealant has minimal odor, making it contractor- and building-occupant-friendly. Its volatile organic compound (VOC) content of less than 10 grams per liter makes it acceptable for use in areas with VOC restrictions. It does not corrode metals.
 

Single-Component Butyl Provides a Permanent Seal Without Hardening

The butyl sealant can be used in a variety of metal roof applications where a low modulus sealant is desired.

R.M. Lucas Co. has added a single-component, non-skinning butyl rubber sealant to its product line. Lucas #8660 provides adhesion and a permanent seal between concealed end laps, metal roof panels, standing-seam roof panels, ridge caps, wall panels and other applications where a non-hardening weather seal is desired. This product is also ideal for use with OEM and shop-assembled metal details.

According to the manufacturer, Lucas #8660 creates a non-hardening, weathertight seal. Designed as a non-skinning, non-sag sealant, the product exhibits high moisture resistance, with an exceptional ability to absorb sound and movement. Lucas #8660 comes in a neutral color, guns easily in cold or hot weather, and is packaged in 10-ounce fiber cartridges, 12 per case.

“Lucas #8660 won’t stain substrates and exhibits primerless adhesion to most roofing and building materials, including Kynar,” says Jason Morris, technical sales representative for Lucas. “The product is easy to gun and tool, even in cold weather, and is also self-healing.”

The butyl sealant can be used in a variety of metal roof applications where a low modulus sealant is desired, including metal roof panels, ribs, standing seams, and ridge cap flashing, as well as metal wall panels. Lucas #8660 is also recommended for OEM trailer and RV application, installation of walk-in coolers and freezers, and as a vapor barrier sealant. In addition, Lucas #8660 can be used as a sound-deadening sealant in installation of acoustical ceilings as well as both gypsum and metal wall panels. It is not designed for use as a single-ply roofing adhesive or lap adhesive.

When applying the sealant, the surface to be sealed must be dry and free of dirt or loose corrosion particles. A primer is not needed. Simply apply the sealant to the area as desired. Tooling is not normally necessary. The product can be cleaned with Lucas #125 Safe Solve. It also has a long shelf life, remaining active two years from the date of manufacture.

“We feel that this will be an excellent addition to our product line whether you are restoring, renovating or maintaining building structures,” states Morris.

Joint and Termination Sealant Designed for Large Joints, Roof Termination Bars

JTS 1 joint and termination sealant from Mule-Hide Products Co. The new JTS 1 joint and termination sealant from Mule-Hide Products Co.allows contractors to quickly and easily seal large joints and roof termination bars – including those submerged under water – with no sagging or shrinking and minimal odor. According to the manufacturer, the 100-percent solids, moisture-cure urethane sealant delivers excellent adhesion to EPDM and PVC membranes, concrete, masonry, wood, vinyl and other common building materials. Primer is required when using it on TPO membranes.
 
The joint and termination sealant is designed to offer exceptional workability for quick, easy application in both dry and wet surface applications. It has a tack-free time of just 30 minutes. The solids content of JTS 1 eliminates shrinking and sagging. The sealant can, therefore, be used to provide watertight closure of joints up to 2 inches wide and 1 inch deep.
 
JTS 1 is isocyanate-free, enabling it to be packaged in durable plastic cartridges without losing workability. Unlike cardboard tubes, the cartridges can be submerged under water to repair roof leaks, gutters and downspouts. They also better withstand the rigors of transportation, storage and jobsite conditions without becoming damaged.
 
Solvent-free JTS 1 has minimal odor. Its volatile organic compound (VOC) content of less than 10 grams per liter makes its use allowable in areas with VOC restrictions. It is available in eight colors – white, black, bronze, gray, limestone, wicker/tan and terra cotta.
