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

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.
