XTEND 19RSS improves
> Booth P52
release and reduces build-up

multi-sector

AXEL’s new solvent-based semi-permanent release, XTEND
19RSS, resolves two of the biggest problems encountered in
closed moulding applications, including LFI and light RTM:
inadequate release and build-up on mould surfaces. Faced with
poor or difficult release, manufacturers resort to more frequent application of release coatings, often compounding the problem, with
more build-up. XTEND 19RSS employs new chemistry to address
these issues, delivering a highly cross-linked coating that is more
resistant to abrasion and impervious to the embedment of residue
that is so common in closed moulding. Customer moulding
tractor and transportation parts in LFI and light RTM operations
have demonstrated that the new release provided twice as many
de-mouldings before requiring re-application. In addition, moulds
ran cleaner for far longer, significantly increasing production. The
product is suitable for a broad range of mould types and resins and
is especially recommended for polyurethane, DCPD and other
chemically-aggressive resin systems. It can be used at both ambient
and elevated temperature, and applied by hand wiping or HVLP
spray.

JEC Europe 2013
Cure with the power of light

> Booth E3

Since the mid-1970s, ultraviolet (UV) energy has successfully cured
inks and coatings. The general benefits of UV technology include:
Almost instantaneous curing; Low to no volatile organic compound
(VOC) or hazardous air pollutant (HAP) emissions; 1K formulations
with a long pot life. UV cure technology is emerging in composite manufacturing, particularly in cured-in-place pipes, pultrusion and filament
winding. Increased productivity and regulatory compliance are two major
reasons why composite manufacturers are adopting UV technology. In
filament winding, the high reactivity of UV systems enables process speed
gains and quicker mandrel re-use. In pultrusion, it results in higher line
speeds and parts with excellent dimensional tolerance, while the longer
pot life reduces waste. Cytec Coating Resins’ line of UV-curable specialty
epoxy acrylates is well suited to the composites industry. EBECRYL® 3720
delivers high Tg, high modulus, fast reactivity and excellent chemical
resistance. For ease of handling, the products can be supplied as dilutions
in various monomers, e.g. HDDA. To improve toughness, modified epoxy
acrylates such as EBECRYL® 3708 can be blended in. Reactive diluting
acrylates are also available to adjust the viscosity of the resin system and influence the physical properties of the cured resin. Cytec’s IBOA is an excellent choice where flexibility, toughness and high Tg are required. HDDA
enables good properties with low volatility.

ArmaFORM PET – a full lightweight product range

> Booth V12

Meeting the growing demand for weight-sensitive, fire-retardant and sustainable products for the composite industry, Armacell extends
its structural core foams with a new low-density range (60 kg/m³). The new lightweight range combines low density with the outstanding properties of the ArmaFORM PET AC, PET FR and PET GR product families. ArmaFORM PET AC60 is the standard for the
requirements of modern composite materials: low weight and high mechanical strength in conjunction with residual flexibility and maximum service life. ArmaFORM PET FR60 offers best-in-class fire properties (NF F16-101; DIN 5510) for weight-sensitive applications
with stringent flame, smoke and toxicity requirements. ArmaFORM PET GR60 is lightweight and made 100% of recycled PET packaging
waste – the ideal combination for highly sustainable requirements. Like all ArmaFORM PET foams, the new 60 kg/m³ density range shows
excellent damage tolerance; outstanding fatigue resistance; very long-term thermal stability; limited density variation (<5%); superior processing temperature of 150°C (short-term up to 180°C); very good thermal insulation properties; fine and closed cell structure for limited
water and resin absorption, excellent mechanical properties; thermoformability; high chemical resistance, no corrosion or degradation;
superior fire resistance; enhanced ecological footprint.
