SP-205 A/B
80 SHORE D SPRAY APPLIED POLYURETHANE
SP-205 A/B is a two component rigid polyurethane material designed to provide high strength, high impact, and good heat resistance
for the fabrication of structural parts, composite type structures, and for coatings that serve many purposes.
SP-205 A/B can be sprayed with conventional plural component high pressure spray equipment or with BJB s CPE-25 and CPE-40
pneumatic hand held spray guns.
Used for rapid production of parts, composite structures, and molds
Provides excellent surface finishes built on polyurethane rigid foam and styrofoam
Superior adhesion to a wide variety of substrates, most notably rigid foams and wood
Excellent impact resistance coupled with high flexural strength
Provides very fine detail reproduction
Convenient 1:1 by volume mix ratio

NON-WARRANTY “Except for a warranty that materials substantially comply with the data presented in Manufacturer’s latest bulletin describing the product (the basis for this substantial
compliance is to be determined by the standard quality control tests generally performed by Manufacturer), all materials are sold “AS IS” and without any warranty express or implied as
to merchantability, fitness for a particular purpose, patent, trademark or copyright infringement, or as to any other matter. In no event shall Manufacturer’s liability for damages exceed
Manufacturer’s sale price of the particular quantity with respect to which damages are claimed.”
Most of the physical properties can be achieved in 5-7 days at 77 F (25 C). You may use your own post-cure schedule but the
physical properties may vary from BJB s cure schedule of 1-3 hours at 77 F (25 C) followed by 16 hours at 180 F (82 C). Do not
exceed curing temperatures of 200 F (93 C). Support of the part may be required to prevent part deformation during the heat curing
process.
STORAGE:
Store at ambient temperatures, 65-80 F (18-27 C). Unopened containers will have a shelf life of 6 months from date of shipment when
properly stored at recommended temperatures. Purge opened containers with dry nitrogen before re-sealing.

SAFETY PRECAUTIONS:
Avoid contact with skin using protective gloves and protective clothing. Repeated or prolonged contact on the skin may cause an
allergic reaction. Eye protection is extremely important. Always use approved safety glasses or goggles when handling this
product. Use in well-ventilated areas. Avoid breathing vapors. If exposures cannot be kept at a minimum, a respirator may be
necessary in addition to ventilation. The use of a positive pressure air supplied respirator is mandatory when airborne isocyanate
concentrations are not known or exceeds OSHA S TWA of 0.005 ppm. Air purifying, organic cartridge type respirators are not
generally recommended to use when handling this material without implementation of an end of life service program. Observe
OSHA regulations for respirator use (29 CFR 1910.134). Employers are responsible for selecting the correct respirator for each
situation.
IF CONTACT OCCURS:
Skin: Immediately wash with soap and water. Remove contaminated clothing and launder before reuse. It is not recommended to
remove resin from skin with solvents. Solvents only increase contact and dry skin. Seek qualified medical attention if
allergic reactions occur.
Eyes: Immediately flush with water for at least 15 minutes. Call a physician.
Ingestion: If swallowed, call a physician immediately. Remove stomach contents by gastric suction or induce vomiting only as
directed by emergency personnel. Never give anything by mouth to an unconscious person.
Refer to the Material Safety Data Sheet before using this product.
WARNING: This product can expose you to chemicals including 1,2-Benzenedicarboxylic acid, di-C9-11-branched alkyl
esters, C10-rich and Titanium Dioxide (TiO2) which are known to the State of California to cause cancer and birth defects or other
reproductive harm. For more information, go to www.P65Warnings.ca.gov.
