Master Bond UV10SP-2A is a one component, flexible, UV curable polymer system for bonding, sealing and coating with an attractive balance of pertinent physical, electrical and chemical properties. It is a 100% reactive, moderate viscosity liquid at ambient temperatures which does not contain any solvents or other volatiles. When exposed to a UV light source, Master Bond Polymer System UV10SP-2A cures as a durable, tough, non-yellowing system which can be used as an adhesive, sealant and coating. UV10SP-2A also possesses excellent electrical insulation properties. Maximum absorption of UV energy takes place in the 250-365 nanometer range. The cured coatings, adhesives and sealants can be used over the exceptionally wide temperature range of -60°F to +250F.
Unlike many other commercially available UV curing products, the Master Bond Polymer System UV10SP-2A is not oxygen inhibited and exhibits a desirably fast curing rate at ambient temperatures even in the presence of air. The Master Bond Polymer System UV10SP-2A can be cured in much greater section thickness (up to 1/8 inch deep) compared to most conventional UV type systems, making it of value for various electronic and opto-electronic potting and encapsulation applications. This performance characteristic is due to its uniquely effective catalyst system. Another noteworthy property of the UV10SP-2A is its high flexibility which imparts excellent vibration and shock resistance as well as superior ability to withstand thermal cycling and thermal shock. Most importantly, UV10SP-2A is readily attacked by most solvents making it the ideal selection when the UV system must be easily removed. The viscosity of this product is adjustable to best meet specific applications.
Master Bond Polymer System UV10SP-2A can be cured in very short time periods depending upon type of UV lamp, distance of the lamp from the surface of the UV10SP-2A, thickness of the section of the UV10SP-2A to be used, etc. Typical cure 200 watt/inch medium pressure mercury vapor lamps are recommended. Curing line speeds as high as 500ft./minute and more have been obtained for thin films of the UV10SP-2A polymer system. No solvents or other volatiles are released during the curing process. UV10SP-2A offers the desirable combination of outstanding durability, toughness and thermal shock resistance as well as excellent adhesion to a variety of many similar and dissimilar substrates. The storage stability of the Master Bond Polymer System is 6 months at room temperature in the original, unopened containers.
