TYPES OF GLUE
There are many kind
of glues in the world for many materials and handmade workings.But we are using
epoxy glue for construction wooden boats like all the other boat builders
because of better potential with woods and plywoods. There are 2 different kind
of epoxy. POXY-SHIELD and POXY-GRIP products are both excellent 2 part epoxy
adhesives, yet each has markedly different qualities.
Primarily,
POXY-SHIELD is a low-viscosity (very fluid) product ideal for coating,
laminating, gluing, and encapsulating wood, but whose applications can be
extended with the addition of our various fillers. POXY-GRIP, on the other
hand, is a high-viscosity ready-to-use (after mixing) structural adhesive not
intended for coating or encapsulating, but not requiring any additives or
modifications either.
First, we realized
that not all builders of all sizes and types of boats would choose or need the
benefits of the total GLEN-L Epoxy Encapsulation System. For example, smaller
dinghies, rowboats, and similar craft built at a low cost, or craft not intended
for ultimate longevity, can still have the high-strength gap-filling bonds
provided by our POXY-GRIP epoxy structural adhesive.
As a glue, POXY-GRIP is
superior to all other types of boat building glues, including plastic resin and
resorcinol types.
In general, the
same recommendations that apply to the building of any craft using other
materials or processes applies to building your boat with the GLEN-L Epoxy
System.
While often seen, do not build your boat in an open area exposed to
direct sunlight. Build indoors or under cover whenever possible, protected from
the direct sun as well as direct exposure to other elements.
Ideal working temperatures range between 70oF and
85oF, although plus-or-minus about 5oF still allows good
conditions for most aspects of the work.
