The Latest in Adhesives and Sealants

Is your company looking for a new flashing method, sealant or spacer system? If so, you’ve come to the right place. In the following pages you’ll find the latest products on the market in the sealants and adhesives arena. 

Instant Results with InstantGlaze

Dow Corning®’s InstantGlaze and InstantGlaze II assembly sealants are patented, neutral-cure, reactive hot-melt silicones designed for automated backbedding applications. InstantGlaze sealant is a 100-percent silicone hot-melt sealant that can be applied robotically using standard dispensing equipment and automated X-Y glazing tables.

According to the company, the sealants prevent “bottlenecking” on the production line because it provides immediate strength upon application, so windows can move on to the next processing step immediately. Likewise, the fast-glazing sealants allow the windows to be shipped immediately once complete and have a lengthy open time, for flexible manufacturing options, according to the company. Finally, the formula is non-hazardous, has a low odor and is worker-friendly.

Window manufacturer Peerless Products in Fort Scott, Kan., is already using InstantGlaze. The company made the switch from traditional glazing tapes in 2005.

“We wanted a new solution that didn’t require hand application and offered customers a higher level of quality, reliability and longevity,” says chief engineer Coby Jones.

So far, company officials have been glad they switched.

“After a year and a half in operation, we have yet to replace a single Peerless window because of performance issues related to the InstantGlaze sealant,” Jones says. “We’ve also seen benefits we didn’t expect, such as better wind resistance due to the flexibility of the Dow Corning® InstantGlaze Assembly Sealant.” www.dowcorning.com

Thiover® is Specially Formulated for IG Units
Fenzi North America’s two-part polysulphide sealant was designed especially for sealing insulating glass (IG) units. The Thiover sealant is produced in different viscosities in order to suit individual customers’ needs and equipment, and is solvent-free. The sealant can be used for either single- or double-seal IG units and can work with any metal profile, according to the company, and can be applied by any type of extruder available in the market, including air, hydraulic, semiautomatic and automatic. www.fenzi-na.com

Venture Tape Introduces Alternative to Rubber Flashing

Venture Tape Corp.’s new VentureFlash 800 is a three-ply, zero-perm laminate (al.foil/PET/al.foil) coated with a special cold-weather (CW) acrylic pressure-sensitive adhesive system. The latest from the Rockland, Mass.-based company combines quick stick at normal temperatures with low temperature performance below freezing, according to information from the company. It can be used with all door and window products, including vinyl, aluminum, wood or fiberglass and can be used in metal building construction.

VentureFlash 800 is self-adhering and has a moisture and vapor barrier to fight mold, mildew and decay. It adheres to a number of different substrates (underlayment and house wraps), including plywood, MDF, Tyvek®, oriented strand board, DensGlass, concrete block, brick, Typar® and buffalo board. www.venturetape.com

Get Precision with VersaPail™

The new line of VersaPail bulk melters from Nordson Corp. is designed to provide precision in the application of hot-melt adhesive from 20-liter or 5-gallon pails. Officials from the Duluth, Ga.-based company say the melters are well-suited for reactive adhesives, such as moisture-cure polyurethanes, and that they only melt the top surface of adhesive allowing the remaining material in the pail to stay solid. This reduces thermal stress and protects bonding characteristics. The system’s hydraulic passages also are designed to eliminate dead spaces where undesired curing could result, according to the company.

Available with a variety of pump types and sizes, VersaPail melters can be customized to accommodate a wide variety of adhesives and meet manufacturers’ specific requirements. An industrial PC provides operators with full control of the adhesive system via an easy-to-use graphical touch-screen interface, with messages and indicators for each activity and machine status condition. www.nordson.com

Servo-Flo® 401 Series Designed for Low Volume
Sealant Equipment & Engineering, Inc.’s new Servo-Flo® 401 Series servo-motor drive meter system is designed to apply small precision beads and small precise shots of adhesives, sealants or lubricant materials from 1 to 8.5 cc in both robotic and manual dispensing applications. Representatives from the Plymouth, Mass.-based company say this new electric meter was engineered to dispense thixotropic and cohesive materials, such as one-part silicones, epoxies, urethanes and heat or ambient cure materials. 

According to the company, the Servo-Flo 401 motor design provides precise and repeatable precision bead profiles and variable-flow-rate metered shot volumes. Likewise, the system provides a variety of preset material-dispensing profiles and will dispense different precise material volumes for various part configurations. The meter accepts flow-rate commands from automation controls or can be preset to vary the flow rate during dispensing. This feature varies the bead volume in gasketing, filling or potting applications in manual, automated and robotic dispensing manufacturing processes. www.SealantEquipment.com/mm1
