Primer for Silicone Roof Coating System Offers Improved Adhesion, Blocks Asphalt Bleed-Through

Mule-Hide Products Co. Multibase SBMule-Hide Products Co. has expanded its Silicone Roof Coating System with Multibase SB, a new primer that delivers stronger adhesion and prevents asphalt bleed-through in non-ponding water conditions. Multibase SB is a one-part, 100 percent acrylic-based resin intended for use as a primer prior to the application of Mule-Hide 100% Silicone Roof Coating. It can be used on modified bitumen, asphaltic built-up roofing (BUR) and PVC roof surfaces.

According to the manufacturer, the primer contains minimal pigment and no mineral fillers, enhancing its adhesion to the roof surface. In addition, its relatively thin viscosity and low surface tension allows the primer to completely saturate the roof surface, further helping form a strong bond.

Multibase SB blocks asphalt bleed-through, helping ensure that white finish coats are clean and bright and deliver optimal reflectivity. The primer can be applied using airless spray equipment, a roller or a brush. Its light yellow color cures to a darker amber hue as the coating dries, providing visual confirmation that the coating has cured and the finish coating can be applied.

It is not intended for use on coal-tar-pitch roofs, on TPO membranes or in areas that experience ponding water. Multibase SB is available in 5-gallon pails and 55-gallon drums.

Low-VOC Aerosol Contact Adhesive/Primer Applies and Flashes Off Quickly

AeroWeb Low-VOC Aerosol Contact Adhesive/Primer The new AeroWeb Low-VOC Aerosol Contact Adhesive/Primer from Mule-Hide Products Co. was designed to boost productivity. According to the manufacturer, the product delivers aggressive adhesion and a quick drying time while going on as much as 60 percent faster than traditional roller-applied adhesives.

The new adhesive can be used in a wide variety of applications, including adhering standard TPO and standard EPDM membranes to horizontal and vertical surfaces; adhering fleece back membranes to vertical surfaces; enhancing the bond between Mule-Hide F5 Air & Vapor Barrier and various substrates; and priming unexposed asphalt prior to applying Mule-Hide HeliX Low-Rise Adhesive for insulation attachment.

AeroWeb’s low-VOC (volatile organic compound), methylene chloride-free formula provides powerful adhesion and a quick drying time in a wide range of temperatures, helping contractors avoid weather-related delays. It can be applied as an adhesive or primer in ambient temperatures as low as 25 degrees Fahrenheit.

Fast, even aerosol application saves crews time while also increasing the coverage rate. Applied using a self-contained spray system, AeroWeb goes on up to 60 percent faster than traditional roller-applied adhesives. The web-like spray pattern also means that the adhesive must be applied to just 75 percent of the surface, versus 100 percent coverage with roller-applied adhesives.

A short tack time and long application window further boost crew productivity. AeroWeb flashes off in less than five minutes, so crews aren’t kept waiting. AeroWeb then remains sticky longer, enabling crews to work with larger sections of membrane.

According to the company, setup is minimal. Clean-up of tools and surfaces is fast and easy using UN-TACK safe solvent or mineral spirits. AeroWeb complies with VOC-related regulations in all 50 states. It is sold in #40 cylinders filled with 30 pounds of adhesive. One cylinder typically covers 1,000 square feet when used as a contact adhesive.

Conductive Primer Designed for Electronic Testing of Conventional Roof Assemblies

Detec Systems has developed TruGround, a conductive primer which enables accurate electronic leak detection (ELD) testing on conventional roof membranes including black EPDM, TPO, PVC, modified bitumen, hot and cold fluid applied. According to the manufacturer, TruGround must be installed directly below the membrane per ASTM D7877. TruGround can be used for quality assurance testing on newly installed membranes and is chemically compatible with fully adhered, mechanically attached and torch-down membranes. Once applied, ELD testing can be performed for the life of the roof. Future breaches or seam voids can be quickly pinpointed, allowing repairs to be done immediately, preventing costly moisture damage from occurring.
