ChemSet VST 3050 High Bond, 20mil, Clear High Bond Tape


ChemSet VST 3050 is a double sided high performance acrylic based adhesive tape, which is especially designed for the bonding of high and medium energy surfaces as well as glass and various transparent plastics where a highly transparent bond is required and no stress corrosion may occur. These tapes conform to various substrate surfaces and absorb the differing thermal expansions of the two different materials. These tapes maintain high impact resistance even at temperatures below 32 F˚ (0 ˚C). Additional advantages of the VST 3050 series include vibration dampening, very good sealing properties, very good resistance to weathering, aging, yellowing (UV influence), chemicals, plasticizers, and excellent long term stability. Some examples of applications are attaching light box / neon advertisements and signs, strip lighting assemblies etc.

General Information:

VST 3050 clear series tape has a closed cell structure which is wind and water resistant. Because they are 100% acrylic based, they will form an almost indestructible bond between the materials. This family is resistant to UV, aging, softening agents and solvents (good plasticizer resistance). These tapes bond immediately and offer extreme resistance to the peel and shear loads that can affect a bond. These tapes are very well suited to absorb dynamic loads as they are viscoelastic, they can act as a sealant, form a permanent tension free bond, and are suitable to bond many different types of synthetic materials.
