EAS-15 EPOXY LAMINATING/ ADHESIVE SYSTEM
EAS-15 is an extra heavy duty epoxy laminating/ adhesive system for use with glass cloth, aramid or carbon fibers and wood laminating and coatings.
The system utilizes one main hardener ECA-032 mixed at a 1:4 by weight ratio with one of two resins, ELV-0020 resin or EMV-0043 resin:
ECA-032 Epoxy Curing Agent, is a room temperature curing agent for liquid epoxy resins. It is designed to minimize skin irritation potential. Used for: In-plant, wet lay-up laminating and tooling. Also used for water-ski, wakeboard and snowboard manufacture, wooden boat and auto-body patch kits. ECA-032 can be used as to make an aggregate bonding mortar.
An elevated temperature cure is recommended for high flexural and tensile strength bonding and laminating.

LAMINATING RESIN: 1
ELV-0020 is a very strong epoxy for laminating and bonding of wooden or composite boat manufacture
ELV-0020 is a low viscosity epoxy resin, characterized by higher performance properties and chemical resistance. When used with amine hardeners, such as ECA-032 or ECA-408, compositions based on ELV-0020 demonstrate excellent physical properties, adhesion, appearance and surface properties.
APPLICATIONS: * Casting
* Electrical
* Laminating
* Tooling
* Flooring
* Coating
* Impregnation
ADVANTAGES:
ELV-0020 is especially good for applications where low viscosity is necessary for good impregnation or maximum filler loading and yet good physical properties are still required.
TYPICAL PROPERTIES:
Epoxy Value, Eq/100g 0.52-0.54
Weight per epoxide (WPE) 185-193
Viscosity, 25 C (77 F) 500-700cps
Color, Gardner 7 max
Density, Lb/Gal. 25 C (77 F) 9.5
Flash Point (Closed cup) 275 F
FORMULATING/MIXING:
Formulations based on ELV-0020 can be easily mixed at room temperature. The low viscosity of the resin permits easy incorporation of hardener, modifiers and fillers.
ELV-0020 can be easily blended with EMV-0043 at different ratios to achieve a higher viscosity.

LAMINATING RESIN: 2
EMV-0043 is a very strong epoxy for laminating and bonding of wooden or composite boat manufacture. This epoxy resin was designed for the wet lay-up laminating of epoxy composites and wood. It has excellent adhesion to many plastics, including P-tex, pbt (and many other substrates). Use at a 4:1 ratio by weight with ECA-032 hardener.
It has been also been used in the manufacture of water-skis and snowboards and snow skis.
