|ER Conventional Epoxy Resins
ER-2: A low viscosity resin for general
purpose applications such as coating, gluing, filling and fairing.
ER-3: A cost effective low viscosity
laminating resin offering high stiffness and compressive strength. It is suitable for use
with glass Kevlar and Carbon fiber reinforcements for many structural applications such as
hulls, decks and support structure.
ER-4: A very low viscosity, high
performance and higher cost laminating resin for high end applications to maximize the
laminates properties and reduce weight.
Toughened Epoxy Resins
DR-5: A low viscosity laminating resin
producing higher fracture toughness and peel strength compared with conventional laminating
epoxy resins. If also offers a superior bonding strength to core materials and is a good
choice for repeatedly stressed structures such as high speed power boats.
DR-7: a higher viscosity version of DR-5
intended as a replacement when roller impregnation equipment is used.
DR-ADTX: A thick fibrous paste adhesive for
applications when low sag and good gap filling qualities are required. Works well in
bonding pre-made skins to honeycomb core.
Hardeners (For use with both ER and DR epoxy resins)
EH-101: A fast curing hardener for use on
small hand laminated parts, gluing and fairing and repair applications.
EH-102: A slower curing hardener providing
a 2-3 hour lay up time. A very good working cure is reached at room temperature (70F)
overnight. A post cure of 3 hours at 160F is recommended to achieve full laminate
properties, but not required for gluing filling and fairing applications.
EH-103: A long 8 hour open time hardener
for laminating large parts. A working cure is achieved after 4 hours at 120F, with a
further post cure of 4 hours at 170F to produce full properties.
provides over 12 hours of working time and is especially suitable for the on going production of large components. This system
requires a minimum of 2 hours at 140F to produce a working cure with a further 6 hours at
160F or 2 hours at 180F required for a full cure.
DH-AD: is a hardener especially for
bonding applications and is typically used with DR-7 resin and DR-ADTX adhesive paste.
This product also maximizes bond strengths to substraights made with polyester and
