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.

Create a Weathertight Seal with a Closure that Contours to a Metal Panel Profile

The newly patented design of LCF Universal Closure by Lakeside Construction Fasteners, Paragould, Ark., creates a weathertight seal by contouring to the metal panel profile without the need for carrying die-cut closures in stock.

“LCF developed this product to be a solution outside of die-cut closures for metal building rollformers and contractors,” explains Eric J. Velliquette, vice president of Sales and Marketing for Lakeside Construction Fasteners. “With the Universal Closure, only one product is needed to conform around various minor/major panel profiles of 1 1/2 inches or less.”

The new close-cell closure can be used as an inner/outer with adhesive applied the full length and width of the LCF Universal Closure. The patented adhesive bonding agent helps prevent water, dirt, snow and insects from penetrating the building structure after installation.

“With our patented UV Inhibitor and Anti-Microbial Coating System, this product can be exposed to direct sunlight or weather without fail,” Velliquette adds. “The aggressive adhesive on the Universal Closure is used the full length and width of the product, so, once attached to the metal panel, it will not fall out of the building structure.”

The LCF Universal Closure System can be used in multiple applications throughout the ridge cap, eave, hip or valley to provided an alternative in-place low-cost solution.

The LCF Universal Closure is Dade County approved to 110 mph, as well as contractor tested and approved.

“A key takeaway is the unique design of the Universal Closure allows for fast contractor installation while conforming to various metal-panel profiles to create a weatherized barrier, keeping the natural outside elements from penetrating the building structure,” Velliquette concludes.
