Hot Melt Adhesive

Hot melt adhesive is available as tape and is designed to be used primarily in conjunction with heatshrinkable tubing and moulded shapes in order to provide sealant / adhesive action at the interface between the encapsulant and the substrate. The adhesive is a specially compounded blend of resins which melts below the shrinkage temperature of heat shrinkable polyolefin products (+135°C) and also bonds to the polyolefin surface and the wide variety of substrate surfaces to which it is applied, eg cable jackets, metal sheaths and connector back shells.

Product #: HMT200A

Specifications

Method of Application
  1. Substrate surfaces should be clean and free from grease and dirt. If necessary, wipe with a suitable solvent.
  2. The substrate should be pre-warmed to reduce its effect as a heat sink.
  3. The HMT200A tape should be wrapped once, under slight tension, around the warm substrate with a minimum overlap. When soft it can be pressed into position.
  4. Heatshrink is then placed over the assembly and recovered by heating.
  5. After the component has been recovered, heating must be continued to ensure that the tape has completely melted, thus ensuring correct bonding.
  6. Any rearrangement of the assembly after the heat-shrinkable component has been positioned must be done whilst the sealant is still molten and the encapsulation is above 120°C. Once set, no stresses should be applied to the assembly until it has completely cooled.
Note Substrates with considerable heat sink characteristics should be pre-warmed. This type of assembly may require even longer post-shrinkage heating to ensure that the HMT200A tape has melted.
