1.DESCRIPTION
BD310 is a two-part methacrylate, 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 1:1, BD310 has a working time of 8 to 12 minutes
and achieves nearly 90 percent of its ultimate strength in 18 to 25 minutes at room temperature
curing. BD310 provides high strength bonds to the above reference surfaces with generally
no preparation effort. BD310 bonds very strongly to steel, stainless steel, and aluminum
metals. BD310 adhesives areNOT UV STABLE, AND WILLYELLOW OVER TIMEand must not
be used to create imperceptible seams in countertops or for seaming countertops. This
yellowingwill notaffect bond performance, but willaffect bond appearance.

6.HANDLING AND APPLICATION:
BD310resin (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 BD310 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 BD310 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. BD310 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 BD310 adhesives are affected by temperature.
NOTE:Because of the curing features of BD310 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 BD310 is twelve (12) months from the date of manufacture based upon continuous
storage at room temperature (77 F or 25 C). Storage of BD310 adhesives in refrigerated
compartments will extend the shelf life even more. Do not store BD310 adhesive or any other
adhesives in a refrigerator which has food or lunch products in them. Be sure to bring BD310
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
BD310 adhesives considerably. Storage at temperatures above 100 F or 38 C could shorten the
shelf life to less than one month. BD310 adhesives contain no water, so freezing of the adhesive for
short periods is permissible, but is not encouraged.
