TECHNICAL DATA SHEET

Description
Metyfix 3, Multi-Purpose Spray Adhesive is designed for the infusion mould market. This produ ct is a high
performan ce, solvent-based polymer adhesive in a pressured aerosol. Metyfix 3, Multi-Purpose Spray Adhesive is
specially designed to hold reinforcing fibres in place during the infusion process of resin without affecting the surface
finish or structural integrity. It is compatible with
polyester, styrene, and vinyl ester resins. This adhesive has also been
successfully tested with epoxy resins using less than 9 grams of adhesive per sqm.

Suitable for use on a variety of substrates including.
Fiberglass
Foam
Balsa
Cork
Fabric
Cardboard
Paper
Other lightweight mate rials

Advantages
Used for Infusion/Vacuum Forming composites.
Safely fuses laminating materials to structural core surfaces.
Provides superior holding during forming process.
Allows resin to
obtain maximu m tensile shear streng th.
Repositionable, if used as a one-sided application.

Directions for use
SHAK E CAN WELL BEFORE USE Make sure that surfaces are clean, dry, and free from dirt, dust, oil, loose paint, wax, or
grease. Temperature of the adhesive and the surfaces being bonded should be between 60F – 80F. Use with
adequate ventilatio n. Spray approximate ly 8 12 away at a 90-degree angle lo the surface. If using a two-way
stick, spray both surfaces to be bonded, Allow the adhesive to tack off. Adhere surfaces and press together with
adequate pressure. After use, turn the can upside down press nozzle until spray is clear of adhesive this will prevent
the nozzle from blocking. If the nozzle has blocked the adhesive can be removed with a solvent such as lacquer
thinner o r acetone.

TECHNICAL DATA SHEET

1. DESCRIPTION

BD420FX is a two-part methacrylate, flexibilized, structural bonding adhesive designed for the
structural bonding of various substrates, including fiberglass, steel, aluminum, and various
plastics (not low energy surfaces). Combined at a ratio of 10:1, BD420FX has a working time
of 3 to 7 minutes and achieves nearly 90 percent of its ultimate strength in 10 to 15 minutes at
room temperature curing. BD420FX provides high strength and very flexible bonds to the
above reference surfaces with generally no preparation effort. BD420FX bonds very strongly
to steel, stainless steel, and aluminum metals and will allow a great deal of movement of the
substrates due to CTE (Coefficient of Thermal Expansion) differences. BD420FX adhesives
are NOT UV STABLE, AND WILL YELLOW OVER TIME and must not be used to create
imperceptible seams in countertops or for seaming countertops. This yellowing will not affect
bond performance, but will affect bond appearance.

6. HANDLING AND APPLICATION:

BD420FX resin (Part A) and activator (Part B) are flammable. Contents include Methacrylate ester
and acids. Keep containers closed after use. Wear gloves and safety glasses to avoid skin and eye
contact. Wash with soap and water after skin contact. In case of eye contact, flush with water for 15
minutes and get medical attention. Harmful if swallowed. Keep out of the reach of children. Keep
away from heat, sparks, and open flames. Do not smoke cigarettes or anything else while handling or
near the product. Refer to the BD420FX Safety Data Sheet for more complete safety instruction. To
assure maximum bond strength, surfaces must be mated together within the specified working time,
and all clamps affixed within that time. Use sufficient material to ensure that the joint is completely
filled when parts are mated and clamped. Avoid over clamping parts, which may cause a dry joint or
a joint starved of adhesive. All adhesive application, part positioning, fixturing, and clamping should
occur before the working time of the adhesive has expired. After the indicated working time, parts
must remain undisturbed until the fixture time is completed. Components bonded, adhesive, and
shop temperature can have a significant effect on the work and fixture time of the adhesive.
Application of BD420FX adhesive at temperatures between 65 F and 85 F (18 C and 30 C) will
ensure proper cure. Temperatures below 65 F (18 C) will slow cure and fixture speed. BD420FX
adhesives will still react, but will take longer. Temperatures above 85 F (18 C and 30 C) will increase
cure and fixture speeds, and there s a risk that the adhesive will be hardened or too thick to bond
materials. The viscosities of BD420FX adhesives are affected by temperature.

NOTE: Because of the curing features of BD420FX adhesives, large amounts of heat are generated
when large masses of material are mixed at one time. The heat generated by the exotherm resulting
from mixing large amounts of adhesive can result in a boiling of the monomer in the adhesive (methyl
methacrylate), resulting in the release of trapped air, steam and volatile gasses. To prevent this, use
only enough material as needed for use within the working time for the product, and confine the gap
or spread out the material to no more than .50 inches.

7. HANDLING AND STORAGE

The shelf life of BD420FX is twelve (12) months from the date of manufacture based upon continuous
storage at room temperature (77 F or 25 C). Storage of BD420FX adhesives in refrigerated
compartments will extend the shelf life even more. Do not store BD420FX adhesive or any other
adhesives in a refrigerator which has food or lunch products in them. Be sure to bring BD420FX
adhesives to room temperature for 24 hours before use, otherwise longer cure and fixture times may
be expected. Long-term storage at temperatures above room temperature will shorten the shelf life of
BD420FX adhesives considerably. Storage at temperatures above 100 F or 38 C could shorten the
shelf life to less than one month. BD420FX adhesives contain no water, so freezing of the adhesive
for short periods is permissible, but is not encouraged.

PACKAGING:
The MP 55420 Series is conveniently packaged in 490 ml, 380 ml, and 50 ml cartridges, pail, and
drum kits. Special packaging is available upon request.

EFFECTS OF TEMPERATURE:
The product is best used at temperatures between 65
0
F and 80
0
F. Temperatures below 65
0
F
will slow the cure speed of the material and viscosities will be higher. Temperatures above 80
0
F
will cause the material to cure faster and viscosities will be lower. For consistent dispensing
maintain temperature in the above mentioned range.

STORAGE AND SHELF LIFE:
The shelf life of the MP55400 Series for most products is one year from date of shipment
(check with ASI). Shelf life is based on the products being stored properly at temperatures
between 55
0
F and 75
0
F. Exposure to temperatures above 75
0
F will reduce the shelf life of
these materials. These products should NEVER BE FROZEN.

PRECAUTIONS:
ASI s MP55400 Series products are flammable. Keep away from heat, spark, and open
flames.

KEEP OUT OF REACH OF CHILDREN. THE PRODUCT IS FOR INDUSTRIAL USE ONLY.
Keep containers closed when not in use. Avoid contact with skin and eyes. Harmful if
swallowed. Refer to Material Safety Data Sheet for complete safety information.

HANDLING AND CLEAN-UP:
For optimum bond strength and to insure maximum performance in the finished assembly
mate parts together within the specified work time of the adhesive. Make sure the bond
joint has uniform coverage and that a sufficient amount of adhesive is in the bond area. It
is important to have the adhesive applied, parts aligned and positioned, within the
established work times for the product. To ensure maximum performance in the finished
assembly parts should remain undisturbed until the fixture time is reached.

Clean up is best before the adhesive has cured. Cleaners containing NMP (N-methyl
pyrolidone) or Citrus terpene provide the best results. On cured adhesive repeat use may
be required.
