- Zero volatile/solvent content
- Improved health and safety: Diuron-Free
- Available with a range of reinforcements
- Suitable for a range of pressures
- Controllable in thick sections
- Low exothermic properties
- Recommended cure between 85ºC and 120ºC

WT93 is part of the WE and WT range of prepreg, SPRINT®, and AIRSTREAM™ products. This unique product range provides technically and commercially competitive engineering materials, ideal for use either solely, or in conjunction with other products from within the product range along with other Gurit products.
WT93 is a hot melt, Diuron free epoxy SPRINT® ideally suited to the manufacture of thick sections. It can be cured at temperatures as low as 85°C, but can also be used for the rapid manufacture of components through its 45-minute cure at 120°C. All of this can be achieved together with an out-life of 75 days at 21°C.
WT93 is designed for vacuum bag processing and offers excellent mechanical performance on glass fibre reinforcements. Currently WT93 is manufactured into a SPRINT® structure with E-glass fibres, which are manufactured into biax or triax materials, these are produced in large volumes in order to make it a cost-effective composite building block for a range of applications.

PHG840(M850-37) - Prepreg materials for railway parts
Components for rail interiors include items like ceilings, floorings, bulkheads, vestibules, fire barriers, interior wall panels, window surrounds, doors, staircases, and luggage bins or racks.
Phenolics are progressively finding their way into railway interior applications to meet increasing and ever more stringent fire, smoke, and toxic fume requirements that most nations apply to passenger railway vehicles operating within their borders.
For further weight reduction, traditional monolithic laminates are replaced more and more with lightweight sandwich constructions with prepreg and honeycomb or foam core.
-Gurit PHG840 rail interior prepregs are a perfect choice to meet today’s railway cost and performance targets:
- Fulfilment of Italian, Spanish, British, French and German rail fire regulation.
- Flexible, autoclave-free processing.
- Fast curing-cycle.
- Very good surface finish.
- White colour after cure for superior cosmetics.

PB1000 - Modified Benzoxazine Resin
-Next Generation Prepreg for Aircraft Interiors
- Fibre reinforced thermosetting preimpregnated material for aircraft interior parts
- No free phenol and formaldehyde, fulfils AP2091
- Non-volatile curing, 140°C / 45min, 160°C / 15min
- Outstanding surface quality
- Excellent FST and Heat Release behaviour, fulfils ABD0031
- Improved mechanical properties
- Long shelf and shop life
Gurit is proud to present its next generation of aircraft interior prepregs based on PB1000. PB1000 is a modified benzoxazine resin that is without free formaldehyde and phenol and satisfies the most recent environmental standards like AIRBUS AP2091. It features a non-volatile, rapid cure, generating a perfect void and porous free surface, through which time and cost consuming rework, is eliminated.
Gurit’s novel PB1000 fully complies with demanding international JAR/FAR fire protection regulations regarding flammability, smoke, toxicity (FST) and heat release. Due to its excellent mechanical performance, PB1000 is perfectly suited to fulfil present and forthcoming stress criteria for interior design.
Meeting increasing demands on cost efficiency in aircraft interior manufacturing, PB1000 is also designed for commonly used fast hot-in / hot-out curing processes. This unique material performance combined with a competitive cost price level makes PB1000 an advantageous choice for aircraft interior applications and is clearly capable to replace phenolic systems.

ST70FR is part of the range of SPRINT® products. This unique product range provides technically and commercially competitive engineering materials, ideal for use either solely, or in conjunction with other products from within the product range along with other SP products from Gurit.
ST70FR is a fire retardant hot melt, Diuron free epoxy SPRINT®. This is ideally suited to the manufacture of thick sections requiring fire protection. It can be cured at temperatures as low as 70°C, but can also be used for the rapid manufacture of components through its 25-minute cure at 120°C. All of this can be achieved together with an outlife of 28 days at 21°C.
ST70FR is designed for vacuum bag processing and offers excellent mechanical performance on glass fibre reinforcements. Currently ST70FR is manufactured into a Single Sided SPRINT® structure primarily with fibreglass reinforcements such as woven WRE581T, WRE850T fabrics and multiaxial XE905 and QE1174 stitched fabrics. Other styles will be available to order.

EP137
- Fiber reinforced thermosetting preimpregnated materials for aircraft parts(e.g.passenger floor).
- Woven fabric of E-glass filament yarn Style 0180, 48 g/m2, plain weave, preimpregnated with 40% epoxy resin EP137 (125°).
- Low-smoke, highly toughened and self-extinguishing epoxy resin system
- Very good FST behaviour
- Excellent adhesion to core materials
- Improved storage conditions at -5°C
EP137-03-40 consists of a E-glass fabric Style 0180, impregnated with the epoxy resin EP137. The highly-toughened resin matrix is a 125°C curing system with a high flameretardancy and low smoke behaviour at fire and provides excellent properties such as high interlaminar shear strength, adjustable tackiness and retarded flow during processing.
The prepreg is perfectly suitable to complement high performance light-weight composite structures meeting the highest requirements of structural interior applications as such as the passenger floor where it is used as a top layer to avoid electro-galvanic corrosion of carbon structure with aluminium and improve overall impact behaviour of the panels.
Both monolithic and sandwich structures can be easily manufactured with this prepreg. The curing can be performed by press, vacuum and autoclave moulding at a temperature range between 120°C and 155°C and a pressure of at least 0.07 MPa.
Such composite structures can be exposed easily to temperatures in the range of -55°C up to +90°C.
