PRODUCT DESCRIPTION
Assembly 161 is specifically designed for use with automatic doweling equipment. Its low viscosity (150 cps.) allows the appropriate flow through the narrow feed lines and injectors of European-made doweling machinery. Assembly 161 sets fast to reduce assembly time, offers excellent strength and provides a translucent glue line. It is formulated for use on solid woods, particleboard, MDF, plywood and other porous materials.
PHYSICAL PROPERTIES
APPLICATION GUIDELINES
Moisture Content: Proper stock moisture content is important to successful dowel gluing. Adhesives generally set more slowly as moisture content of the wood increases. Dowel holes can also become out of round as the moisture content decreases. Recommended moisture content ranges are 6-8%.
Machining: Dowel holes should be cut accurately with sharp tools. Dull tools cause burnishing of the dowel hole and prevent glue penetration. The dowel hole should also be free of torn grain which will produce a high percent of surface wood failure but relatively little strength.
Part Fit: To obtain maximum strength, the dowel should fit snugly into the dowel hole. Too tight of fit will push the glue into the bottom of the hole. Conversely, too loose of fit will produce a heavy glue line, and ultimately, tweak the joint. A small space between the bottom of the dowel and the bottom of the hole (1/16”) will allow room for expansion of the dowel without producing stress cracks.
Minimum Temperature: Curing temperatures should be higher than the minimum use temperature of the adhesive. This includes the temperature of the stock to be glued as well as the air and adhesive temperatures. Machine settings: consult with machine manufacturer's recommendation for details.
OTHER ADHESIVES
Assembly 161 is designed for use in automatic dowel insertion equipment. Most of our customers find that the viscosity is too low for hand doweling. Franklin Adhesives & Polymers has a complete line of assembly glues to help you complete the dowel joint. Recommended adhesives in order of increasing viscosity are: Assembly 8-5% (950 cps), Assembly 8 (1,500 cps), Assembly 65 (3,500 cps), Assembly 70A (8,000 cps), Assembly T-2A (16,000 cps) and Assembly TX-Brown (40,000 cps). For additional information, contact Franklin Adhesives & Polymers.
PERFORMANCE PROPERTIES
HANDLING AND STORAGE
Store in tightly closed original container. Protect from freezing. Storing at temperatures above 25ºC will reduce the maximum storage time. If thickening, separation or settling occurs, the adhesive should be thoroughly mixed and will then be ready to use again.
