Devcon	Tru Bond 18401 Pressure Sensitive Light Cure Adhesive

PRODUCT DESCRIPTION

DEVCON UV-PSA series of one-part, solventless adhesives offer a patent pending technology with two distinct curing advantages. First, this material can be cured through previously assembled clear or translucent substrates to form an immediate adhesive bond of high optical clarity. The second benefit is that this material can also be dispensed onto any substrate, clear or opaque, and then exposed to UV light to form a tacky, fully cured, PSA surface. This allows for the immediate assembly of mated parts or for assembly at some future point. Included in the unique physical features of this product is the ability to bond a wide range of substrates including PE, PP, Delrin, and most plastics, metals, glass, or ceramics. The adhesive can be used to form clear bondlines made as a film surface, coating, or bead. Typical Physical Properies. Uncured Material.

Applications. • Sign making and other graphic assembly. • Touch pad, membrane pad and other keypads. • Automotive interiors - trim, graphics, light panels. • Lamination of foam, foils, any plastic film, felt, mesh, etc. • Form-in-place gaskets and O-rings - replace die cut forms. Peel Test. These products are relatively low tack materials after UV. The immediate peel strengths are 1-4 pounds per linear inch (pli), rising to 8-12 pli after 12 hours. Final peel values are the same regardless of dwell after UV exposure. Peel adhesion is evaluated according to the Pressure Sensitive Tape Council Method Number 1 (PSTM 1). Adhesive is applied to Mylar film and cured for 1 J/cm² of UV light. These strips are then placed on top of 1-inch wide steel laps and rolled with a 4.5 pound weighting. Peel strength is tested 30 seconds and >12 hours after lamination and is reported as the continuous value in pounds to maintain a 90° peel.
