Power Adhesives Tecbond 420 General-Purpose Spray Hot Melt Glue Slugs

Designed for spray-based assembly processes, Tecbond 420 is a polyolefin hot melt adhesive commonly used in applications where controlled working time and material protection are critical. Supplied in 1 3/4" (43 mm) glue slug form, it is frequently selected for mattress production and HVAC assembly due to its ability to bond plastics (excluding PE), foam, fabric, and bubble film. The formulation provides an open time of approximately three minutes, allowing components to be positioned accurately before final compression.

Rapid cooling helps minimize heat transfer to sensitive substrates when Tecbond 420 is applied, supporting consistent results in foam- and film-based assemblies. Spray application delivers broader adhesive coverage than traditional bead patterns, while the material can still be extruded as a controlled bead when precision placement is required. Designed for efficient production workflows, Tecbond 420 carries UL 2395 approval for securing thermal insulation and can replace mechanical fasteners such as nails and tacks in carpet and skirting board installation.

Tecbond 420 Glue Slug Features and Benefits

  • Spray or Bead Capability: Designed for spray use with the flexibility to be extruded as a bead for targeted bonding when needed.
  • Extended Open Time: The three-minute open time supports precise positioning of substrates without loss of tack during assembly.
  • Substrate Protection: Rapid cooling helps prevent melting or burning of sensitive materials during application.
  • Enhanced Coverage: Spray application delivers a stronger bond across wider surface areas compared to bead guns.
  • Industry Certification: Tested and approved to UL 2395 for securing thermal insulation in HVAC appliances.
  • FDA Compliance: Meets FDA 175.105 requirements for indirect food contact applications.

Excellent adhesion on foam and wood

This is a great product and I highly recommend it. I mainly use it to glue polyethylene foam into wood shipping crates. Also works great for bonding foam to foam.
