EAS–19 EPOXY ADHESIVE

EAS-19 is a two-part epoxy compound, specially formulated for use in wooden boat manufacture and as general purpose wood glue. Its low viscosity and a special propriety additive enhance good wet-out and penetration. Also, built-in flexibilizing additives provide tough, shock and vibration resistant bonds.

EAS-19 has been used on many different types of woods and wooden structures, as a good general purpose adhesive. A typical hull construction for a multihull would be using unidirectional E-glass cloth laid over a klegecell foam core.

EAS-19 is designed for use in a five (5) to one (1) mix ratio in accordance with the commonly used metering pumps. Bonding can be carried out successfully down to 40 deg. F but for optimum bond strength and other physicals, cure at 70 - 75 F is recommended.

Because of its low mixed viscosity this adhesive can be readily mixed with fillers. When used as a coating, thinners can be added if desired. QCM is also a manufacturer of epoxy pigment dispersions that can be used to create colored epoxy coatings and adhesives.

This product has been used extensively in the manufacture of multihulls and hydroplanes.

Many older boats and interior structures have also been repaired using EAS-19 to strengthen and reinforce the rotten or rotting wood. Repair is done by diluting

EAS-19 with small amounts of MEK (Methyl Ethyl Ketone) for a first penetrating coat and then overcoating with uncut epoxy/hardener.

(1) Final physical properties for epoxies cured at lower temperatures are not as good as those cured at higher temperatures and should be tested for adequacy.

(2) All epoxies (and most other materials) noticeably harden when cold and soften when hot. End use application should take this into consideration.

DIRECTIONS FOR USE: For best results, surfaces should be sound, clean, dry and free of alkalinity or acidity. Adequate bonds may be obtained with less than ideal surface preparation, but user must determine suitability. Temperatures above 50 degrees F have typically produced superior results.

PRECAUTIONS: Mix only an amount of material that can be used within the pot life.

Epoxy material may be skin irritating. Avoid contact with skin and eyes. For skin contact, wash thoroughly with soap and water. For eye contact flush immediately with water and consult a physician. EAS-19 contains epoxy resins, polyamides and modified phenols. For further information see MSDS.

CLEAN-UP: Uncured epoxy may be cleaned off tools and most surfaces with methyl ethyl ketone (MEK), toluene or blends of the two. (CAREFUL! THESE SOLVENTS DISSOLVE MANY PLASTICS.)

SHELF LIFE: Guaranteed six (6) months when stored in sealed containers at temperatures between 50 - 90 F. Part A subject to crystallization when stored in intermittent cool temperatures for prolonged periods.
