Introduction to Spabond™ 400

Spabond™ 400 is a new generation, toughened, structural epoxy adhesive for high dynamic load applications, comprising of 4 systems:
  • Spabond™ 435: Ideal for thin bondlines such as core bonding, large surface areas and detailed work.
  • Spabond™ 440: Optimised for rapid dispense from cartridges or automated mixing machines.
  • Spabond™ 445: For large gap filling & filleting applications as well as high performance projects, with a black resin option available.
  • Spabond™ 400FR: structural fire retardant epoxy adhesive

Why is Spabond™ 335, 340LV and 345 being replaced?

Kleben mit Spabond 400

Spabond remains a key adhesive brand for Marine and industrial applications The Spabond™ 300 series is being replaced because:

  • Opportunity to Improve handling and processing properties, dispensing & carbamation resistance
  • Simplify the portfolio, moving from 13 to 5 components
  • Improved Health & Safety


Spabond™ 400 offers customers the same benefits as the Spabond™ 300 series, with improved Health & Safety, application and performance advantages

What is changing?

Spabond™ 400 is a new product range that covers the full functionality of Spabond™ 335, 340 and 345. The simplified portfolio has 3 resins with increasing sag resistance.

  • 10mm: SP335 = now SP435
  • 20mm: SP340 = now SP440
  • 30mm: SP345 = now SP445


All resins use the same 2 hardeners:

  • Spabond™ 400 Fast: ½ hour working time
  • Spabond™ 400 Slow: 3 ½ hour working time
    • 6 hour thin film working time
    • 15 hour clamp time

Benefits of Spabond™ 400

Spabond™ 400 Improved Handling & Application

Spabond™ 400 has been formulated to improve handling & application performance:

  • Improved dispense and sag resistance recovery
  • Improved manipulation & filleting performance
  • Robust to high humidity application

Enhanced Curing Profile

Spabond™ 400 Series only has 2 hardener speeds: Fast and Slow

Spabond™ 400 Slow hardener combines the key characteristics of the Spabond™ 300 series Slow and Extra-Slow hardeners:

  • Longest hardener thin film working time (SP345 Extra-Slow) of 6hrs
  • Fastest overnight clamp time (SP340 Slow) of 15 hours
  • This allows enough time to bond large structures whilst maintaining an overnight initial cure

Improved Health & Safety

The current 300 series hardeners contain substances of very high concern (SVHCs).  Gurit Internal policy and external legislation mean these need to be removed or improved. Spabond™ 400 hardeners are low toxicity formulations:

  • Improved Hazard Labelling
  • Free of Carcinogens, Mutagens & Reprotoxins (CMR’s)
  • Free from Substances of Very High Concern (SVHC’s)
  • Reduced Environmental Hazards

  • Self-extinguishes following UL-94 type test (represents V0 classification)
  • Low toxicity & halogen free
  • Simple 3:1 mix ratio by volume
  • Available with fast hardener
  • Excellent gap filling properties
  • Good thermal, mechanical & adhesive performance
  • RINA Certified:
    • Surface materials and floor coverings with low flame-spread characteristics
    • Adhesives used in the construction of ‘A’, ‘B’ & ‘C’ class divisions

Mix Ratio – why has it changed?

The viscosity of the hardener component has a large impact on the sag resistance of the mixed system. Moving to a 3 : 1 mix ratio, reduces the amount of hardener and change in consistency of the mixed system. Allows us to have 2 hardeners for use with 3 resins with a sag resistance of 5 to 30mm.

Improved packaging concept

Correct Size Cartridge Boxes

Reduced waste & empty volume & more stable to prevent collapse in transit.
