We use a high quality, exterior grade, two-part catalyst glue for use in a radio frequency press.

Advantage® 405 is a highly water-resistant, 2-part crosslinking polyvinyl acetate emulsion adhesive with a low minimum use temperature. This very high performing adhesive conforms to section 6.2.1 of the North American Fenestration Standard 101/I.S. 2 NAFS-02. It has surpassed both the ASTM D-5572 wet use finger joint and ASTMD-5751 wet use edge glue standard. This versatile adhesive can be used for finger jointing, edge gluing, hot pressing,and radio frequency gluing.
Chemical Family Description: Crosslinking polyvinyl Typical Viscosity (cps):
acetate emulsion adhesive Uncatalyzed: 1,800-3,800 4/60/83°F
Appearance: Beige colored liquid Suggested Minimum Use Temperature:
Freeze/Thaw Stable: Yes Per Gallon (Weight lbs.): 9.25
pH: 6.5-7.6 Weight Solids (%): 50-54%
The normal recommended portion of catalyst to resin is 5% by volume (one quart to five gallons). A reduced proportion can be used under certain conditions such as burning in a radio frequency press. Mixes containing less than 2½% by volume should be avoided.
Place the resin in mixer and slowly add catalyst while stirring. Continue mixing for five minutes after all the catalyst has been added to ensure a uniform mixture.
Moisture Content: Six to eight percent is the recommended moisture content of the gluing stock. High moisture content will slow down glue line cure and cause weaker than normal adhesive bonds. Additionally, panel shrinkage may occur resulting in stress cracks or end delamination.
Stock Preparation: The preparation of the stock to be glued is extremely important. Joints cut from rip saws should be free of saw marks. They should also be straight and square. Moulded or jointed stock should be free of knife marks. Glazed or burnished joints will prevent glue penetration and should be guarded against. When possible, glue joints should be prepared and glued the same day. The stock should be machined on both top
and bottom surfaces to allow even contact with radio frequency platens.
Spread: Generally, 35-50 pounds per 1,000 square feet of glue line (6-9 wet mils or 180-260 ft²/gal) is adequate. Conveyorized spreaders are commonly used in this application. The use of a wool felt sleeve on the spreader roll can aid in obtaining a desirable spread and reducing excess glue usage.
Pressure: Pressure is dependent upon the species or material to be glued. Direct contact of the gluing surfaces must be achieved to obtain maximum strength. Suggested pressures for various substrates are; high pressure laminates 30-80 psi; solid core stock 100-150 psi; all veneer constructions 100-250 psi.
